Ultra 15 kHz Assembly System User’s Manual
System Overview
Ultra Series components are among Dukane Corporation's most
technologically advanced. These components can be manufactured for a variety of applications. Each thruster or press can
function independently, or a system can also be integrated with
a customer’s automated machinery.
The 15 kHz assembly system excels in providing superior weld
consistency and extensive control when joining larger parts.
A typical system includes a thruster, a 4,000 watt generator to
supply power, a press, and a Ultra-Com High Power Process
Controller. The Ultra-Com is a process controller providing
essential control and monitoring features for ultrasonic welding
operations. An accessory, the Advanced Programmer, can be
added to allow the operator a more efficient method of programming and monitoring the welding process.
Making the System Operational
To operate the system an acoustic stack (or simply, “stack”)
consisting of transducer, booster, and horn must be added. In
addition, a fixture into which the assembly parts are placed and
welded is required.
Press/Thruster Similarities and Differences
Both presses and thrusters include the following:
• a housing for the stack assembly,
• a pneumatic system for raising and lowering the stack and for
applying pressure to the part,
• gauges, switches, and controls to regulate stack movement, to
control the stack clamping pressure on the part, and to start
and stop the ultrasound signal.
A press support package is included with a press making it selfsupporting by providing a rigid support frame, and machine base.
In its standard configuration, a thruster does not include a support package, and must be mounted to a rigid support of some
kind. (The support package is available as a thruster option.)
Usually a thruster is used as a part of an automated system
where it is mounted within a special configuration.

Section 1 Introduction and Safety
Key Features of the Press/Thruster
• Ultra-rigid Square Support Column with rack and
pinion height adjustment and up to 10° of radial alignment capability.
• Heavy Duty Precision Slide assembly with 1" (25.4
mm) diameter steel rods and sealed Thomson ball bushings preloaded for reliable, frictionless operation.
• Height Adjustment Handwheel is supplied, and it can
be specified for mounting on either side of the press.
• Gas Strut counterbalence for easy height adjustment.
• Stroke of 6.75" (171 mm) with mechanical bottom stop
adjustable in .001" (.025 mm) increments.
• Dual Pressure allows for an increased clamp force improving melt during the weld cycle, or greater pressure in
the Hold portion of the cycle to strengthen the weld.
• Calibrated Dynamic Trigger system with LED indicator
starts the ultrasonic signal at a precise, user-selectable force.
• Pre-trigger and End-of-Weld (lower) limit switches are
standard and adjustable in .001" (.025 mm) increments.
• Top-of-Stroke limit switch for automated applications.
• Ergonomic Base and cycle activation switches reduce
operator fatigue; optional opti-touch cycle activation
switches are available.
• Status Indicators in base for POWER, IN CYCLE, and
ABORT clearly communicate system operating status.
• Twist Release EMERGENCY OFF switch on the press base
meets international safety standards.
• Advanced Programmer keyboard and monitor provide an option for more efficient programming.

Ultra 15 kHz Assembly System User’s Manual
Health and Safety Recommendations
Please observe these health and safety recommendations for safe,
efficient, and injury-free operation of your equipment.
NOTE
These recommendations apply to the welding system. “System” in
this manual refers to a complete group of components associated
with the welding of parts, also known as an ultrasonic assembly
system. A typical Ultra System consists of the Ultra-Com ultrasonic process controller, a generator, a press with thruster,
switches, controls, cables, transducer, booster, horn, and fixture.
Proper Installation - Operate system components only after
they are properly installed.
No Unauthorized Modifications - Do not modify your system
in any way unless authorized to do so by Dukane Corporation.
Unauthorized modifications could cause equipment damage and/
or injury to the operator. In addition, unauthorized modifications
will void equipment warranty.
Keep the Cover On - Do not remove any equipment cover
unless directed to do so by Dukane Corporation.
CAUTION
At some time you may be asked to remove equipment covers by the Dukane Service Dept. personnel. Before doing so, disconnect the unit electrically from the incoming line AC power. If the unit is a press/
thruster, lock the Air Lockout Valve, located on the rear
panel, in its closed position. See Figure 3-5 on Page 36.
Grounded Electrical Power - Operate this equipment only with
a grounded electrical connection. (See Electrical Safety Grounding Instructions on Page 8.)
Comply with Regulations - You may be required to add accessories to bring the system into compliance with applicable regulations
(OSHA in the USA) for machine guarding and noise exposure.
6
Section 1 Introduction and Safety
CAUTION
Parts being joined ultrasonically with the Ultra 15
kHz press will vibrate at audible frequencies.
Wear ear protectors to reduce annoying or uncomfortable sounds. In addition, ultrasound
baffles, sound enclosures, or materials that absorb sound
may be located to surround the system.
Acoustic Stack Hazard - When an acoustic stack (transducer,
booster, horn and tip) is energized by the ultrasound signal, it
presents a potential hazard. Stay clear of an energized stack.
WARNING
Keep head, hands, limbs and body at least
six inches (152 mm) away from an operating
press/thruster. A vibrating, descending horn
can cause burns and/or crushing injuries.
System Abort Switch - Install a system abort switch at each
operator station when ultrasonic plastic assembly equipment
is used with automatic material handling equipment in an
automated system.
Foot Switch - Using a foot switch in place of dual palm
buttons (activation switches) violates OSHA regulations.
Pre-trigger Switch Adjustment - The pre-trigger switch
option starts the horn vibrating before contacting the part to
be welded. The pre-trigger must be adjusted so that the
ultrasound signal will not start if the horn is more than 1/4
inch (7 mm) from the part. This ensures safe operation.
System Electrical Cabling - Electrical power must be off
when connecting or disconnecting electrical cables.
CAUTION
When making cable connections to system
equipment or disconnecting cables from system
equipment, make sure electrical power to the
system is turned off, and AC power cords are removed from
their receptacles. After the cables have been securely connected and the connections and cable routing checked a
final time, the power may be restored.
7
Ultra 15 kHz Assembly System User’s Manual
Special Health Notice – Plastics
Before using any Dukane ultrasonic system, become familiar
with applicable regulations about the particular type of
plastic(s) you are using. (In the USA check with the U.S.
Department of Labor.)
When plastic materials are being processed, they may emit
fumes and/or gases that could be hazardous.
Make sure there is proper ventilation whenever these plastics
are processed.
Electrical Safety Grounding Instructions
For safety, the power cords used on all Dukane products have a
three-prong, grounding-type plug. The type typically used with
the Ultra-Com is shown in Figure 1-1. The plug typically used
with the 4000 watt generator is shown in Figure 1-3.
CAUTION
If you must use a two-prong electrical receptacle,
we strongly recommend that you replace it with
a properly grounded three-prong type. Have a
qualified electrician replace it following the
National Electric Code and any local codes and
ordinances that apply. See Figures 1-1 and 1-2.
CAUTION
If there is any question about the grounding of
your receptacle, have it checked by a qualified
electrician.
Do not cut off the power cord grounding prong
or alter the plug in any way.
Extension Cord: If an extension cord is needed, use a threewire cord that’s in good condition. The cord should be large
enough to do the job safely. It, too, must be plugged into a
grounded receptacle. Do not use a two-wire extension cord
with this product.

Ultra 15 kHz Assembly System User’s Manual
Additional Grounding
Grounding lugs have been provided on the Ultra-Com, generator, press base, and thruster (See Figure 1-4.) to meet any
additional grounding requirements that may arise.
Use 18 AWG ground wire for the ground connection between
the press/thruster, the Ultra-Com and the generator.
RFI Filter Considerations
In addition to the safety considerations above, proper grounding at the generator power cord is essential for the effective
operation of the RFI (Radio Frequency Interference) filter in
every Dukane generator. The filter prevents line
noise from entering the control circuitry of the
ultrasonic equipment, as well as blocking
ultrasonic RFI from the power
line.

Before unpacking your equipment:
WARNING
Cartons and their contents are heavy. Use
mechanical means to move the cartons. Lifting
or carrying them manually could result in
personal injury.
1. Move Shipping Cartons: Carefully move the shipping
carton(s) as close to the final installation site as practical.
2. Utilities: Make provision for a stable compressed air supply,
that is clean and dry between 80 and 100 psi. Also provide
for electricity to meet your equipment specifications.
NOTE
Compressed air must be
delivered at a higher
pressure than the expected output pressure,
and in a range of 80 100 psi.
3. Space Requirement: Check that enough space has been set
aside for your installation.

Unpacking
WARNING
DO NOT LIFT your press
system manually. Lifting
and/or carrying a press
manually could result in
personal injury.
Use mechanical means to
move and place your press.
System components are packed in a variety of ways depending
on what has been ordered. For instance, a typical press system
(thruster, column, and ergonomic base with integrated palm
switches) comes in a carton resting on a plywood shipping
base and the carton bottom. Other system components like the
Ultra-Com and generator are packed separately.
To unpack a typical press:
1. Remove the straps from the carton.
2. Open the top of the carton. Carefully remove the packing
material and any accessories, cables and documentation.
3. Cut the tape at the bottom corners and unfold the flaps.
4. Carefully remove the carton, as shown in Figure 2-1, leaving
the press on the shipping base. Inspect the system components before placing them in position. Immediately report
any damage found. See the NOTE below.
See Section 12 – Specifications. Table 12-1 lists the standard
components for both press and thruster systems.
Carefully
Remove Cart
on
NOTE
Questions or problems? Call your sales representative or the
Sales Department at Dukane Corporation Headquarters for
most concerns. If reporting damage, contact the carrier first.
Save all shipping containers and packing materials so they
can be inspected in processing any claims that may arise. For
additional help contact Dukane Support/Service. See Section
11 for contact information.

Placement
Press with Base
Use a pallet lift platform or its equivalent to raise the
assembly until the bottom edge of the base is even with
the top of the benchtop, as shown in Figure 2-2. Then,
carefully slide the press system onto the benchtop.
Alternatively, hook the
press support on the lifting
eye-bolt, and use a meLifting Eye-Bolt
chanical hoist to lift the
unit into place.

Figure 2-2 Press Placement
Press without Base
When the press and thruster have been configured without a
base, secure the base flange to a stationary, rigid and level
supporting structure. To fasten the flange to the structure,
Dukane Corporation recommends using socket-head cap
screws: M12-1.75 with a minimum length of 40 mm. Engage
the cap screws a minimum of 1 inch (25.4 mm) full thread
into the supporting structure. Depending upon the structure’s
thickness and material, longer screws and/or additional
hardware may be required.
Flange Template Provided
A full-scale template of the base flange is provided as Page 25
of this section. Use it to position (and drill) holes in the
supporting structure.

Ultra 15 kHz Assembly System User’s Manual
Press System Thruster Height Adjustment
Loosen
Thruster height on the column is adjustable by using the two
column clamps together with the height adjustment wheel
and the six Allen (locking) screws shown in Figure 2-4.
WARNING
Keep hands away from the horn and
fixture when loosening the column clamps.
When the clamps are loosened, the
thruster and acoustic stack could drop toward the
fixture and injure the equipment operator. This could
happen if the combined weight of the thruster plus
the acoustic stack is greater than the air cylinder
counterbalance’s ability to counteract that weight.
Figure 2-3a Loosening
the Column Clamps
Tighten
To make adjustments:
1. Carefully loosen the two clamps on the column by turning
the handles counterclockwise, as shown in Figure 2-3a. When
the clamps are loosened, the air cylinder counterbalance on
the column helps to support the weight of the
thruster.
2. Grasp the handle on the height adjustment
wheel as shown in Figure 2-4. Turn the wheel
clockwise to raise the thruster. Turn it counterclockwise to lower the thruster.
3. When the thruster is at the desired height,
tighten the clamps by turning their handles
clockwise, as shown in Figure 2-3b.
NOTE
Height of the entire press/thruster
can be adjusted with the adjustment
wheel as much as 17.5 in (440 mm).
The thruster slide assembly stroke is
a maximum 6.75 in (170 mm).

Optional Connections
Complete cable connections for any optional features.
Linear Encoder
If your unit has the linear (distance) encoder, connect the
encoder’s free end to connector J12, THRUSTER STROKE ENCODER
on the back of the Ultra-Com. (See Pages 39-42 for more information about the encoder.)
Top-of-Stroke Cable
This optional cable connects the thruster’s J40, TOP-OF-STROKE
SWITCH connector to the customer’s automation system. The
switch in the thruster opens when the press/thruster slide assembly returns to the fully retracted, or top-of-stroke position. This
contact closure is typically used with automated systems to indicate to the controlling mechanism that the slide assembly is fully
retracted.
NOTE
Under normal use, we recommend that the maximum voltage and
current applied to the contacts do not exceed 24 VDC @ 2 amps.
Recheck Connections
Recheck all connections, and when they are all secure, you are
ready to connect electrical power.
Connect Electrical Power
As a final step in the cabling of your system, connect electrical
power to the Ultra-Com and to the generator. See Section 12,
Specifications, for input power requirements.

Ultra 15 kHz Assembly System User’s Manual
Installing the Thruster
NOTE
Each installation presents its own set of conditions for the installer. The information offered here is a general guide to
thruster installation.
If installing the thruster by itself, make some decisions about
your own setup factors. Then, use the steps outlined below as a
guide in mounting the thruster.
Setup Factors
Height Adjustment
Mounting a thruster on a rigid, stationary support structure
means the thruster itself cannot move. Therefore, after the
thruster is installed its height cannot be adjusted.
NOTE
In its fully extended position, the thruster slide assembly will have
moved approximiately 6.75 inches (about 170 mm) from its
retracted position.
Space Considerations
If the thruster height cannot be adjusted, position the thruster so
that the distance from the tip of the retracted horn to the top of
the assembly part in the fixture is less than 6.75 inches. (Extension of the thruster slide is a maximum of about 6.75 inches or
about 170 mm.) If the distance is greater, the horn will be unable
to reach the part to be welded.
In addition, be certain there is enough space for placing and
removing parts.
20
TIP
A shorter distance to
travel (stroke)
between the retracted
horn tip and the parts
in the fixture during
operation gives two
advantages:
• A thruster that is
more stable (than
one fully
extended) when
applying pressure
to the parts, and
• A shorter duty
cycle for a greater
production rate.
Section 2 Installation
Mounting the Thruster
1. Place the back of the thruster onto the
support structure.
Examples of this structure: a weldment, a
frame, or a baseplate.
Dowel Pin Hole (2)
2. Align the thruster with the
support structure. This can be done by
using the thruster bolt holes and/or
dowel pin holes to align with bolt
holes and dowel pins of the support
structure. See Figure 2-7.
The thruster has three threaded
mounting holes.
3. Insert three mounting bolts (3/8-16
x 1-1/4" hexhead or equivalent)
with flat washers, as shown in Figure
2-7.
Washer
Bolt
Support Structure
Horn
Fixture
Figure 2-7 Mounting the Thruster
4. Adjust the thruster so the horn meets
the fixture at the proper angle for your applcation.
5. Tighten the bolts.
Connections for Thruster Only
1. Make the basic cable connections 1 through 7
as shown in Figure 2-8 and as detailed on the next
page. When connections are complete, the thruster, the
Ultra-Com, and the generator will be interconnected.
2. Make any optional
connections.
3. Connect any customer supplied equipment such as
automation, chart recorder or printer.
4. Complete basic connections with customer-supplied
air and electricity.
Connect the power cords last, but do not turn on
the power yet.
CAUTION
Before connecting
or disconnecting
cables for any system component:
Turn off electrical power.
Remove power cords from
receptacles.
Put the front panel power
switches for both the UltraCom and the generator in
the OFF position.

Air Gauge (PRESSURE)
The gauge displays the amount of pressure being
applied during the Weld and Hold portions of the
cycle. The gauge registers pressure from both Pressure
1 and Pressure 2 regulators respectively.

Pressure 1 Adjustment Knob
Pressure 1 is the pressure inside the air cylinder used: as the
slide assembly descends; during the Weld portion of the
cycle; and, as the slide assembly retracts. The adjustment
knob connects to an air regulator.
To set Pressure 1:
1. The Pressure Select Switch button is normally in the
WELD PRESSURE position.
2. Watch the PRESSURE gauge needle, and turn the adjustment knob — clockwise to increase air pressure, and
counterclockwise to decrease air pressure.
3. When the air gauge displays the desired welding pressure, Pressure 1 is set.
4
Pressure Select Switch (WELD PRESSURE/HOLD PRESSURE)
This switch is used to select either the Weld Pressure (Pressure 1) regulator or the Hold Pressure (Pressure 2) regulator.
This can be done to set the pressures and to montior them.
5
Mechanical Stop Adjustment Knob
To move the stop (and also the indicator flag), turn the
Mechanical Stop Adjust knob: counterclockwise to lower it,
and clockwise to raise it.
This provides a way to stop the slide:
• at a particular depth of travel relative to the fixture, or
• to prevent the horn from contacting the fixture when
there is no part present.
6
Pressure 2 Adjustment Knob
Pressure 2 is the pressure inside the air cylinder used during
the Hold portion of the weld cycle. The adjustment knob
connects to a second air pressure regulator.
To set Pressure 2:
1. Press and hold the Pressure Select Switch button to HOLD
PRESSURE.
2. Watch the PRESSURE gauge, and turn the knob clockwise
to increase pressure; turn it counterclockwise to decrease
pressure.
3. When the air gauge shows the desired Hold pressure,
Pressure 2 is set. Release the Pressure Select Switch.
30
Section 3 Controls and Indicators
When welding with dual pressure, both regulators are
active though at different times in the weld cycle. Pressure 1 regulator is active as the slide assembly descends
and during the Weld portion of the cycle. Pressure 2
regulator is active as the Hold portion of the weld cycle
takes place.
7
Ultrasound Active Status Light (WELDER ON)
This light glows green whenever the ultrasound signal
is applied to the stack.
8
Indicator Flags
The flags can provide visual feedback for three aspects of
the weld process: END WELD, PRE-TRIGGER, and STROKE
POSITION. Only the STROKE POSITION flag moves with the
slide assembly itself.
To find out how far this slide assembly moves:
When the slide is in its “up” or retracted position, note
the top edge of the middle flag is aligned with the “00”
on the stroke position scale.
Then, when the slide assembly is fully extended, note
where the top of the flag is. That is the stroke distance.
See the EXAMPLE below.
EXAMPLE
The STROKE POSITION flag starts at the 0 mark on the
scale. At the extension of the slide assembly, the position of the flag is at the 10 mark.
Subtract 0 from 10, and the result is 10 centimeters. This
means that the slide assembly has moved 10 centimeters.
END WELD
and PRE TRIGGER flags move when their corresponding adjustment knob is turned. Readings are
taken from the top edge of these flags.
See 9 and 10 on the next pages for more information.

Pre-trigger Adjustment Knob
NOTE
Turning the knob clockwise lowers the PRE TRIGGER flag
increasing the distance traveled before the ultrasound
signal is turned on. The flag shows where the ultrasound
signal will be turned on. The signal can start either before
the horn contacts the assembly part or after contact is
made. As the horn descends, the ultrasound signal stays
on until the weld controlling parameter (time, distance, or
energy) has been met or until the tops of the STROKE
POSITION and END WELD indicator flags are even.
NOTE
Refer to the Ultra-Com User’s Manual as you decide on the
trigger settings. Make sure your Ultra-Com setup corresponds to
the mechanical adjustments you have made to the press itself.
When pre-trigger is not needed for an application, turn the
knob so the indicator is at the bottom of its slot.
CAUTION
Adjust the pre-trigger flag so the ultrasound
signal will not start until the horn is 1/4 inch
(7 mm) (or less) from the part to be welded.

End Weld Adjustment Knob
Turning the knob moves the END WELD indicator flag.
The top edge of the flag shows where the ultrasound
signal will be turned off.
When the pre-trigger control is used to start the ultrasound signal (as the horn descends), the end weld feature can be used to shut off the ultrasound signal. As the
horn descends, it will reach the point where the STROKE
POS indicator flag is even with the END WELD indicator
flag. The ultrasound signal will shut off at that point.
When an application does not require the end weld feature, position the END WELD flag at the bottom of its slot.
NOTE
The End of Weld input for the Ultra-Com comes from the End of
Weld press indicator flag, and it is used to end the weld portion of
the cycle based on the press head position. The flag can be manually raised or lowered to end the weld at an absolute distance. The
End of Weld feature is generally not used with a press or thruster
equipped with a distance encoder.

Trigger Control Knob
This control allows the operator to select what “preload”
or amount of force will be applied to a part before the
ultrasound signal is turned on.
A pressure switch in the slide assembly closes when a
specific amount of force applied to the horn is reached.
The trigger control adjusts the amount of force needed to
close that pressure switch. When the switch closes, the ultrasound signal starts, and the horn begins to vibrate.

TIP
The mechanical stop is
used in two ways. On
swage and insertion
applications it is used to
stop the weld at a particular depth.
On all other applications, it is used to prevent the horn from

Section 4 Press Options
Overview
This section provides information for several common
options:
• Linear Encoder,
• Electronic Pressure Regulator,
• Pressure Transducer, and
• Force Transducer.
Linear Encoder
An optional device for your Ultra 15 kHz Assembly System is
the linear encoder, also known as the distance encoder. It
may have come with the original system purchase, or it may
have been purchased as an “add-on” after the initial system
installation had been made.
Purpose
The linear encoder accurately measures the distance travelled by the
slide assembly and ensures that slide
assembly movement can be precisely controlled and monitored.
To Ultra-Com J12
Components
The linear encoder kit, P/N 438-846.
consists of:
• encoder scale,
• encoder head and mounting plate
• modified right side press panel, and
• mounting hardware.

Installing the Linear Encoder Kit
Remove Standard Right Side Panel
1. Close and lock the air lockout valve. (See Page 36.)
2. Turn off the Ultra-Com and the generator. That leaves the
press without power.
3. Remove the right side panel (with the DUKANE Ultra logo
on it) from the press.
4. Remove the side cover held by 2 flat-head screws. Save the
screws.
5. If a top-of-stroke switch is supplied, remove it from its switch
bracket. Then remove the switch bracket from the casting.
NOTE
The encoder scale and head are joined, so please, do not
attempt to separate them unless directed to do so.

Testing
1. Unlock the padlock used on the air lockout valve.
2. Connect the encoder cable to connection J12 at the rear of
the Ultra-Com (THRUSTER STROKE ENCODER).
3. Turn on the Ultra-Com. This restores power to the press as
well. Set the Ultra-Com to measure distance.
4. Set the air pressure to the desired level.
5. Perform the following procedure to test the encoder for the
proper setting:
a. Run one weld cycle. If the encoder position reads negative (-.xxx) then the encoder is above the “0” reference
point used to measure distance by the Ultra-Com. This is
the correct setting. Secure the two screws on the encoder
head, and proceed to Step 6.
xxx = approximately -.125 to -.250
b. If, after running one cycle, the encoder position reads
positive (+.xxx), loosen the two encoder head screws, and
slide the head down until the reading goes negative
(-.xxx). Secure the two screws. Proceed to Step 6.
6. Set the gap between the encoder scale and head, using a
.039 inch (1 mm) feeler gauge blade.
7. Measure the gap at the top and bottom of the stroke. Allowable tolerance, as specified by the encoder manufacturer, is
±.005 (range from .034 to .044 inches or .864 to 1.12 mm).
8. Loosen and tighten all the screws as necessary, and check the
measurements again after tightening them.
Attach Side Panel
Install the modified right side panel with its five (5) 1/4 turn
retaining pins. Route the encoder cable through the notch in the
thruster’s aluminum casting.
Connect the cable to the J12 connector on the Ultra-Com.

Section 4 Press Options
Electronic Pressure Regulator
The electronic pressure regulator, (I/P transducer) is an
electro-pneumatic replacement for the manually adjusted air
regulator on the press. The I/P transducer converts electrical
signal current (I) into air pressure (P). The Electronic Regulator takes an electrical signal sent by the Ultra-Com, and
converts it to the programmed air pressure.
The pressure value settings, “Pressure 1” (P1) and “Pressure 2”
(P2), are stored in the Process Setup under Pressure in the UltraCom. P1 and P2 are set in pounds per square inch (PSI), or
BARS.
To monitor Pressure 1 and Pressure 2 values, use the CHECK
PRESSURE parameter, contained in the Utilities menu under
User Parameters (on the Ultra-Com).
The Ultra-Com uses a pressure transducer to measure the I/P
output pressures.
Calibration
The I/P transducer installed in this thruster/press does not
require on-site calibration. The unit is equipped with selfcorrecting, closed-loop circuitry.
Pressure Transducer
The pressure transducer (P/I transducer) performs the same
function as the air gauge on the press. The P/I transducer
converts the air pressure (P) to an electrical signal current (I).
It then sends the signal to the Ultra-Com. The Ultra-Com
displays this signal as pressure.
Two sets of upper and lower limits can be monitored with
the pressure transducer:
• One set of limits is used to monitor the air pressure before
a cycle starts. Using the bad parts limits, the unit will not
begin a cycle if the air pressure is outside the pressure
window that has been set.This set of limits is used to
ensure that air pressure from the input line has not
dropped below the pressure required for an acceptable
weld force.
Continued
43
Ultra 15 kHz Assembly System User’s Manual
Pressure Transducer, continued
• The other set of limits is used to monitor the air pressure
when the ultrasound is turned on.
This feature can be used as an indicator when checking for a
trigger or load cell malfunction.
A more precise method to monitor trigger force is to use a load cell.
Calibration
The pressure transducer does not require any on-site calibration.
Load Cell
A load cell (force transducer) is a device that measures force.
The load cell converts mechanical force into an electrical signal.
The load cell monitors the force applied to the part. It sends a
signal to the Ultra-Com to indicate when the mechanical pressure is equal to the programmed “Trigger Force”. The trigger is
the point at which the ultrasound is turned on.
The Trigger Force parameter can be viewed from the Utilities
menu with the Ultra-Com. Choose USER PARAMETERS, then choose
TRIGGER FORCE. The values for this parameter are in pounds or
Newtons.
A force versus time graph can be generated if a printer is connected to the Ultra-Com.
Load Cell Calibration
The load cell is calibrated at the factory. It does not require any
on-site calibration.

Stack/Fixture Setup
• This section outlines steps needed to
remove and assemble an acoustic stack.
It also discusses fixture installation.
Dukane Corporation

Dukane Corporation
Section 5 Stack/Fixture Setup
Overview
The Dukane Ultra 15 kHz Assembly System is used to assemble
parts in a wide variety of applications. The ease with which
acoustic stack components can be installed and exchanged helps
make this possible. In addition, this flexibiltity makes regular
inspections and maintenance of the stack easier to perform.
This section tells how to change stack components. Removing
the stack, disassembly, assembly and installing the stack are
covered. The information applies to a first-time installation as
well as when a change to an existing setup is called for.
Stack Description
The stack consists of three primary components (see Figure 5-1):
• Transducer,
• Booster, and
• Horn.
For an original equipment system, the transducer and booster
are usually shipped assembled and installed in the thruster.
The horn, horn tips, and fixture are shipped separately.

NOTE
When changing or inspecting any of the stack components,
ALWAYS remove the stack from the thruster.
Continued
47
Ultra 15 kHz Assembly System User’s Manual
Stack Removal, continued
Electric Shock Potential Explanation
Transducer performance depends on the nature of its piezoelectric
makeup. Electrical energy is converted to mechanical energy when
the stack is in use inside a press/thruster. After the press has been
turned off, and handling the stack becomes necessary, keep in
mind that any electrical charge that has built up inside the transducer will discharge from the contact button. So, when removing a
stack from the press/thruster, do not touch the transducer’s contact
button. Set the transducer aside. Wait a few minutes, and usually
the charge will dissipate completely.
Once removed from the press/thruster, the transducer is capable of
converting mechanical energy to an electrical charge.
For instance, electrical energy might be produced if the transducer
experiences a change in temperature or if the transducer receives a
physical blow of some kind. Again, any electrical charge that
results from these kinds of mechanical forces would be focused at
the contact button.
Receiving a transducer shock would be similar to a shock you may
experience when touching a household light switch after crossing a
carpeted floor.

Section 5 Stack/Fixture Setup
Stack Disassembly
Use the two spanner wrenches (wrenches A and B) provided
with the press. To separate the stack components, read and
carefully follow the instructions below:
1. Place wrench A on the component to be removed, and
place wrench B on the component next to it. Refer to
Figure 5-4.
2. Turn wrench A in the direction indicated.
CAUTION
Avoid injury when using the spanner
wrench(es). Press down with the palm of
the hand on the wrench handle.
A
3. When the component is loose, it can be removed by hand.
NOTE
To maintain structural integrity, when separating components
NEVER hold a transducer by the housing or the booster by its
mounting rings. Doing so will damage the holding pins in
both the transducer and the booster.
B
Figure 5-4 Stack Disassembly
NOTE
Use only the tools recommended by Dukane. NEVER clamp a
horn, booster, or transducer in a vise or use tools such as
pliers, visegrips, etc. Doing so will scratch and/or gouge the
surfaces and introduce stress risers in the stack. The irregular
surfaces would affect the stack operation, and that could lead
to failure of each stack component. The stress risers could develop into cracks causing the stack components to fail.
49
Ultra 15 kHz Assembly System User’s Manual
Stack Assembly
Preassembly Check
Before assembling a stack, inspect all of the components for
possible damage. Take a few moments to inspect the surfaces
to be joined. They should be smooth and clean.
Look for surfaces that are uneven (concave, convex), have
stress cracks, chips, or gouges. Any of these irregularities will
affect the operation of the stack, and could cause further
damage. Refer to Section 9 – Maintenance, for steps to take in
cleaning or smoothing the mating surfaces.
If the components have no damage, continue with the following steps:
NOTE
A pitted surface or one that has a buildup of old grease and
dirt, will interfere with the transfer of energy from one component to another.
1. Remove any foreign matter from the threaded stud and
the mating hole.
2. Put a thin coat of high-pressure grease (A small packet is
supplied with the system.) on one of the mating surfaces.
If high-pressure grease is not available, then use a thin
coat of petroleum jelly.
NOTE
Do not apply grease or lubricant to the stud or to its corresponding mating hole.
3. Thread the components together, and tighten them
(Figure 5-6) by applying torque as follows:
250 inch-pounds = 20.8 foot-pounds, or
28.2 Newton-meters.
CAUTION
Do not overtighten. Overtightening components can cause stress cracks, stud loosening,
or unexplained power supply overloading.

thruster just before stack installation.
2. Place the stack inside the thruster with the transducer
and booster resting on grooves designed to match with
their mounting rings. Make sure the contact button on
the top of the transducer meets the electrical contact
leaf of the thruster.
3. Support the stack in this position with one hand on the

6. Place a part in the fixture.
7. Grasp the horn firmly, and pull the acoustic stack assembly
down until the horn is as close to the part as necessary to
align the fixture.
8. Tighten the fixture hold down bolts to secure the fixture.
9. Adjust the mechanical stop (See Section 3, Controls and
Indicators.) so the horn will stop above the fixture. This will
prevent horn damage if the acoustic stack assembly descends
when a part is not in the fixture.
NOTE
Some applications may require the horn to be a few thousandths
of an inch from contact with the fixture.
Special applications may require the mechanical stop to be
lowered so the horn makes contact with the fixture or anvil.
When this is required, then a ground detect circuit is needed to
terminate the weld cycle. Refer to the Ultra-Com User’s Manual
for more information about providing a ground detect circuit.
54
Section 5 Stack/Fixture Setup
Leveling the Fixture
The following procedure may be helpful, in some applications, in leveling the fixture. To perform this procedure, you’ll
need a piece of carbon paper and a piece of white paper.
1. Put a sample part in the fixture.
2. Place a piece of white paper on top of the sample part.
3. Place a piece of carbon paper, carbon side down, on top
of the white paper.
4. Enter the following into the Ultra-Com:
Weld time = 0.05
Hold Time = 0.00
Pressure = 20-40 psi
System parameters = Use default settings.
5. Set the trigger control, on the thruster, so the pressure
switch closes after some pressure is applied.
6. Turn on the power to the generator and to the Ultra-Com.
7. Make sure the Mode Selection Keyswitch on the Ultra-Com
Front Panel is in the OPERATE position.
8. Cycle the equipment, normally, by depressing the left and
right base activation switches or by triggering the automation switch.
When one cycle is complete, the pressure developed between
the horn and the sample part will have left marks from the
carbon paper on the white paper. If the fixture is not level,
the carbon markings will be darker in some areas than in
others. All carbon markings will be uniform when all the
proper adjustments have been made.
Make adjustments, and repeat this procedure as necessary
until you are confident that the fixture is level.

4000 Watt Generator
Overview
The 4000 Watt generator converts 60 Hz/240 Volts AC power
into a 15,000 Hz signal with an amplitude exceeding 1,000 volts.
This signal is fed through the Ultra–Com unit which controls it,
to the horn assembly in the thruster/press.
Safety Consideration
To avoid possible injury and to operate the equipment in a safe
and efficient manner, please observe the following safety measures. Note that some of the items are also applicable to system
components other than the generator, such as the acoustic stack
assembly or ultrasonic press.
• Do not operate any system components before they
are properly installed.
• Do not make any unauthorized modifications to the
control circuitry or other parts of the system. This
could cause damage to the equipment and/or injury
to the operator. Unauthorized modifications may also
void the equipment’s warranty.
• Do not operate this equipment without a properly
grounded connection.
• Accessories may be required for compliance with applicable OSHA regulations for machine guarding and
noise exposure.
• When ultrasonic plastic welding equipment is used
with automatic material handling equipment such as
an automated system, a SYSTEM ABORT SWITCH
should be used and located at each operator station.
• Do not use of a foot switch in place of dual push
button switches. This violates OSHA regulations.
• The Ultra 15 kHz Assembly System will produce audible frequencies. Ear protectors may be worn to reduce annoyance or discomfort from the resulting
sound. In addition, sound baffles, sound enclosures,
or acoustical absorbing material may also be needed.

AC Power ON/OFF Switch — This rocker switch under the AC
POWER light controls electrical power to the generator. When the
power is on, the indicator light, AC POWER is illuminated. This
switch is also a circuit breaker for overload protection. When
the circuit breaker opens, the switch rocks back to the off
position. When the circuit breaker rocks the switch to the off
position, the equipment requires servicing.
OPERATE/STOP/TEST Switch — This switch provides a means of
turning on and off the generator’s ability to produce ultrasound.
The three switch positions are explained below.
OPERATE Position — This is a ready position. With the switch
in this position, the generator will start the ultrasound when it
receives a signal from the digital timer (timed systems) or a
switch closure (continuous firing systems).
STOP Position — This is an off position. The generator cannot
generate ultrasound when the switch is in this position.
TEST Position — Use this position only for evaluating the vibrational characteristics of the stack with the “Operational Stack
Test.” See Section 7. This position activates the generator ultrasound. DO NOT use this position unless an acoustic stack (or
probe) is connected to the generator, or damage to the genera61
Ultra 15 kHz Assembly System User’s Manual
Front Panel Controls, continued
tor may result. The O/S/T switch is spring loaded to return
from this position to the STOP position automatically when
released. Therefore, the switch must be manually held in the
TEST position.
OUTPUT POWER LEVEL — The front panel meter indicates the
percentage of power drawn from the generator when the ultrasound is on. The power drawn varies with each operation. The
meter scale, ranging from 0 to 10, represents 0% power drawn.
For instance, 2 represents 20% power drawn, and 10 represents
100% power drawn. If the meter reading is in the red portion of
the scale, beyond 100%, a power overload exists, and the red
OVERLOAD light will be lit. Turn the system off. Then, retest the
stack using the “Operational Stack Test” in Section 7.
Red OVERLOAD Light — The red OVERLOAD light is lit to indicate
a mismatch between the ultrasound signal and the vibrational
characteristics of the stack that the generator is driving. It also
lights when too much power is drawn from the generator, and
the meter reading is in the red. At either time, damage to the
generator may occur. When the OVERLOAD light glows or flickers, stop operation, and retest the stack using the “Operational
Stack Test”.
POWER Control Knob — This control provides for fine adjustment of the stack amplitude. To achieve optimum efficiency
from this generator, set this control to as high a setting as possible. Use an exchange of boosters, whenever possible, to vary
the amplitude so that this control may remain at a high setting.
Auto-Trac Range Control Potentiometer — A small plug between
the POWER knob and the O/S/T selector switch conceals the
Range Control “Pot”. Section 7 of the User’s Manual, explains
how this potentiometer may need adjustment in the process of
matching characteristics of an acoustic stack to the generator
output.

System Test
• This section explains how to test the stack
before the press is put into full production.
Dukane Corporation
This page intentionally left blank
Dukane Corporation
Section 7 System Test
Overview
To operate a Dukane ultrasonic assembly system efficiently, the
ultrasound signal from the generator must match the frequency
and phase characteristics (vibrational characteristics) of the acoustic stack it drives. Each stack has unique vibrational characteristics depending on the combination of its components. In addition, the characteristics of a particular stack may vary slightly
from cycle to cycle because of temperature and loading factors.
Auto-Trac Tuning
The generator’s Auto-Trac feature in combination with Dukane’s
patented Phase Lock Loop-Pulse Width Modulation circuitry
enables a match between the generator’s signal and the characteristics of a particular stack.
The Auto-Trac feature automatically adjusts the ultrasound signal to match the stack’s vibrational characteristics. The moment
the ultrasound turns on during each operating sequence, the
Auto-Trac monitors stack motion on a cycle by cycle basis adjusting the ultrasound signal to an optimal level.
Because the Auto-Trac continuously monitors each operating
sequence, it compensates for vibrational changes that occur
during repeated operations due to heating of the stack components. It also compensates for aging of the piezoelectric crystals
in the transducer and for horn wear.
The Auto-Trac feature excels in environments hostile to reliable
operation such as high stress, continuous duty applications, or
high duty cycles in bursts. With this ability to automatically determine the optimal setting for a stack during each operation, the
Auto-Trac feature permits the use of one generator with multiple,
sequence-fired stacks. In such a situation, the Auto-Trac compensates for the unique, vibrational characteristics of each stack due
to differences in aging, loading, temperature, and to the many
differences in horn configurations.
67
Ultra 15 kHz Assembly System User’s Manual
Operational Stack Test
Before beginning to operate the system for a “full production run”,
verify that the stack’s vibrational characteristics fall within the AutoTrac’s range. To do this, complete the Pre-test Checklist and the
Acoustic Stack Test explained below.
NOTE
All Dukane stack components are manufactured to specifications
within the generator’s Auto-Trac range. A non-Dukane horn, an
improperly assembled stack, or a stack component that is worn or
damaged can produce vibrational characteristics outside these
specifications.
Pre-test Checklist
1. Make sure that the correct booster and horn, specified for
the application, are installed in the thruster.
2. Check the press, Ultra-Com, and generator for proper grounding.
3. Check the ultrasound cable connections, on the generator,
Ultra-Com, and thruster for proper seating and security.
4. Verify that the horn is not under load (in contact with a
fixture or part).
68
Section 7 System Test
Stack Test, continued
Acoustic Stack Test
1. Turn the generator’s AC POWER switch ON.
2. Perform a test by manually holding the spring-loaded OPERATE/STOP/TEST (O/S/T) selector switch in the TEST position. Compare the generator’s indications with TABLE 7-1
below.
3. Release the selector switch, and it will go back to the STOP
position.

Table 7-1 Test Procedure Indications
If the first three steps of the test were completed successfully,
the stack is operational. Proceed to Step 4 on the next page.
If the displays show other results, there may be a problem
with the stack.
NOTE
If the ultrasound signal should stop due to an overload condition, the meter will indicate “0”, and the OVERLOAD light
will glow. The generator overload protection circuit has shut
down the ultrasound signal.
**
NOTE
The generator is operating
at the optimum setting for
this stack when the meter,
during this test, is between
5% and 15% of the full
meter scale. Horn and
booster amplitude and the
mass of the horn determine
the amount of energy
needed to vibrate the stack.
This combination of factors
for a particular stack determines whether the optimum setting is closer to 5%
or to 15%.
TIP
To monitor stack performance while in the SETUP
mode, record data from
the Ultra-Com POWER display, a menu item on the
U tilities Page, whe n
equipment is new, and
also on a regular basis
over the life of the unit.
This “history” will be valuable in tracking system
performance.

4. To see if the ultrasound signal is being transmitted to the horn:
First, fold a small scrap of paper once (ordinary 20# copy paper
will work for this purpose), and place it on the press base or
fixture about an inch from the tip of the horn.
Turn the selector switch to TEST.
The paper should “bend” slightly away from the horn as shown in
Figure 7-1. If no movement is seen, there may be a problem with
the stack. Release the selector switch so that it returns to the STOP
position.
Figure 7-1 Paper Test
NOTE
Under normal conditions, the 15 kHz ultrasound signal can be
easily heard. The paper test provides a visual confirmation of
the active ultrasound signal.
Acceptable Results
If all the indicators from Steps 1-4 are acceptable, the stack is
within the Auto-Trac range. Proceed to Running Sample Parts
and Making Adjustments.
Unacceptable Results
If one or more of the indicators are unacceptable, go to Step 5.
5. Turn the generator and Ultra-Com off. Check the stack for
correct assembly, damaged components, or dirty mating
surfaces. Make any repairs or adjustments to the stack. Recheck the ultrasound cable for proper connections. Repeat
Steps 1 through 4. If the test still fails, go to Step 6.
6. Turn the generator off. Remove the stack from the thruster,
and remove the horn from the stack. Resinstall only the transducer-booster assembly into the thruster. Repeat Steps 1-4 of
the previous page.
70
Section 7 System Test
Stack Test, continued
Good Indications with Horn Removed
If good indications are given with the horn removed, it means
that the horn is outside the specifications required to operate within the Auto Trac preset range.
Reassemble the horn to the stack, and go to the “Range
Adjustment of the Auto-Trac Feature” that follows.
Bad Indications with Horn Removed
If bad indications are present with the horn removed, check
the booster and the transducer for the following:
• any visible damage,
• loose or cracked stud, or
• pitted or dirty mating surfaces.
Make any necessary repairs or adjustments.
Go to Step 7.
7. Repeat Steps 1-6. If the bad indicators disappear, reattach the
horn to the stack, and repeat Steps 2-4.
• If any bad indications are still present, do not run this
stack. Call Dukane Service for assistance.
Range Adjustment of the Auto-Trac Feature
NOTE
Do not adjust the Auto-Trac range unless the preceding
Stack Test procedure directs you to do so. New Dukane
horns are designed to operate with “home” for the AutoTrac range control being set at the three o’clock/nine
o’clock position. If you adjust this control to operate an
older or non-Dukane horn, return it to the home position
before trying to run another horn.
The goal of this adjustment is to run the horn without any of
the bad indicators shown in Table 7-1.

Verify that the horn is not under load (in contact with a fixture
or part).
2. Remove the plug button from the front of the generator to
reveal a slot on the Auto-Trac range control potentiometer
hereafter referred to as a “pot.” If the pot has never been
adjusted, it should be in the 3 o’clock/9 o’clock position as

If the ultrasound signal remains on, go to Step 6.
If the ultrasound signal stops, the meter’s needle will drop to
zero, and the OVERLOAD light will glow. Release the switch so
that it moves to the STOP position, and go to Step 5.
5. Use a flat blade screwdriver to turn the control pot about 1/8
of a turn in either direction. Repeat Step 4.
72
Section 7 System Test
Auto-Trac Range Adjustment , continued
NOTE
Each time you return to Step 5, turn the pot another 1/8 turn
in the same direction it was turned at first. (The pot has a
mechanical stop just short of 180 degrees from the home position in both directions.) If the stop is met in one direction
and the ultrasound signal will not stay on, return the pot to the
home position. Then repeat Steps 4 and 5 turning the pot the
other way.
If the signal will not stay on after followng the above steps,
do not run the horn until it is evaluated and the situation resolved. Discuss the details with Dukane personnel.
The horn may need to be sent in for evaluation.
Move the slot on the control pot to the home position, and
replace the plug button in the generator front panel.
6. While holding the O/S/T switch in the TEST position, slowly
turn the control pot in one direction, and then the other
direction. Find a position where all of the bad indicators
disappear. If the ultrasound signal shuts off, release the O/
S/T switch. Return the pot to a position where the signal
stayed on. Repeat this step while turning the pot in the
oppostite direction. The pot has a mechanical stop just less
than 180 degrees from the home position (either direction).
If the signal will not stay on after completing the above steps,
do not run the horn until it is evaluated. Discuss the details with Dukane personnel.
Move the slot on the control pot to the home position, and
replace the plug button in the generator front panel.
If there is a position where the bad indicators disappear, try
turning the pot a bit more to find the position with the lowest
possible meter reading. Release the O/S/T switch to the STOP
position when this is done, and go to Step 7.
7. Record the position of the range control pot to operate
this particular stack with your Ultra-Com/generator. When
using this stack in the future, adjust the range control
before completing the Operational Stack Test. Put the plug
button back into the generator front panel, and remember
to leave the control pot in the 3 and 9 home position
before using another horn.
73
Ultra 15 kHz Assembly System User’s Manual
Cycling the System
1. Check that you have correctly performed the following:
a. Installed the stack in the thruster and securely closed the
stack access cover.
b. Secured the fixture in place.
c. Completed the Operational Stack Test.
2. Select the Ultra-Com OPERATE mode with the Front Panel mode
select keyswitch. Also set the OPERATE/STOP/TEST switch on
the generator to the OPERATE position.
3. Verify that all controls, on the press/thruster and the UltraCom, are set as required for this operation.
4. Place a part in the fixture.
5. Cycle the system. If using the dual push button activation
switches to start the system cycle, press them both simultaneously, and hold them until the ultrasound signal starts. Releasing the activation switches before the ultrasound starts
will abort the cycle.
74
Section 7 System Test
Running Sample Parts
When monitoring an application, two elements that should always be observed are Power Draw and Assembled Part Quality.
If sample parts are made using an acceptable power draw, and
if they meet quality standards and any other application-dependent criteria, then a full production run can be initiated.
Power Draw
Before cycling the system, get in position to watch the Ultra-Com
Front Panel display where POWER can be shown. From the UltraCom SETUP menu choose UTILITIES, then POWER UTILITIES, then POWER.
How much power is being drawn from the generator?
Discontinue operation if the meter needle moves into the red area
or if the OVERLOAD light glows at all. The generator will no longer
produce an ultrasound signal while in an overload condition.
TIP
The most important
elements to monitor
are always dependent
on the application.
For instance, Time,
Distance, and Energy can be critical
elements to watch.
For more information, refer to Table
10-1 which gives examples of weld
characteristics and
their relation to system components.
CAUTION
Repeated operations that draw too much
power from the generator can damage system
equipment.
If Overloading Occurs
If overloading occurs, discontinue the operation.
Perform the Operational Stack Test (described above)
or see Section 9, Troubleshooting for more information.
Assembled Part Quality
Check assembled part quality for the following:
a. Strength of the joint or seam, and
b. Appearance: Does the assembled part meet the quality
standards for appearance?
Making Adjustments
If the samples are not acceptable, make adjustments as necessary. If further assistance is needed, contact Dukane. Section 11
lists the Dukane contacts.

Section 8 System Operation
Overview
When system installation is complete, and sample parts have
been successfully assembled, the system is ready for an
extended run.
This section of the User’s Manual provides a checklist to use
before start-up, and it gives some basic operating instructions
on starting and stopping the system.
Daily Start-up Checklist
= YES Answer each question with a “Yes”, before starting:
1. Cables (pages 15-25)
Are all cables properly connected with retaining rings
screwed tightly in place?
2. Grounding (pages 8-10)
Is the customer-supplied “source ground” properly connected to the Ultra-Com, generator, and press/thruster?
3. Air Filter For units equipped with the press support package.
Is the air filter at the rear of the thruster clean ?
4. Air Lockout Valve (page 36)
Is the valve unlocked and in the “open” position?
5. Acoustic Stack (pages 45-53)
Is the stack properly assembled and installed in the
thruster, and is the stack access cover securely bolted?
6. Horn, Booster, Fixture
Are the horn, booster and fixture correct for the application to be performed? Check all three items for cracks,
chips and alignment.
7. Mechanical Stop (page 34)
Will the mechanical stop prevent the horn from hitting the
fixture (when a part is not in the fixture)?
8. Ultra-Com and Generator (Ultra-Com: See User’s Manual P/N 403-393C;
Generator: See Section 6 of this manual.)
When power to the Ultra-Com and generator was turned
on, did the units complete start-up sequences successfully?

Start-up
After completing the Daily Start-up Checklist, you are ready for
system start-up. See the previous page for the Checklist.
1. Turn air power on.
2. Perform the Operational Stack Test as outlined in Section 6 of
this User’s Manual.
3. Verify that all controls, on the press/thruster, on the UltraCom and on the generator are set as required for your particular application.
4. Place a part in the fixture.
5. Start the system manually or automatically.
Manual Start
If using the dual push button activation switches to start the
system cycle, press them both at the same time, and hold them
until the ultrasound signal starts.
NOTE
Releasing the buttons before the ultrasound starts causes an error
in the start-up sequence, and the cycle will stop.
Automatic Start
The system may be activated using customer-supplied controls
that are linked through the Ultra-Com to start the cycle automatically based on a predetermined sequence of events.
6. After the system has started, monitor the Ultra-Com and the
generator output for overload indications.

Section 9 Maintenance
Overview
Maintenance information is organized under these headings:
• Stack Maintenance,
• Reconditioning Stack Components,
• Torque Values, and
• Press/Thruster Maintenance.
Stack Maintenance
Overview
NOTE
See Section 6 for generator maintenance, and see
the Ultra-Com User’s
Manual for that unit’s
maintenance requirements.
It is essential that the mating surfaces of all stack components
(transducer, booster, and horn) are flat and smooth. When the
surfaces of the components are joined and tightened, there
must be no “air gap” between them.
If a gap of any
kind remains, no
matter how small,
Mating Surfaces
there will be a
Mating Surfaces
loss in power,
output, and
efficiency. In
some cases, the
union of the
mating surfaces
could be so poor
as to prevent a
stack from starting. That would Figure 9-1 Location of Stack Mating Surfaces
happen because
excessive power
draw occurred as
a result of the
bad surface
contact.
Continued
81
Ultra 15 kHz Assembly System User’s Manual
Inspecting the Stack
Look at the mating surfaces to see where the shiny, burnished
areas are. These areas show where the surfaces have been in
contact, and indicate that the surfaces themselves are either
flat or uneven.
Hole for
Mounting
Stud
}
Surfaces with Even Contact
A flat surface has made even contact, and will be uniformly
burnished across its entire contact area.
Figure 9-2 illustrates that type of contact.
Burnished
Area
Figure 9-2 Burnished Area Indicates
Flat Mating Surfaces
Surfaces with Uneven Contact
Crowning
}
A surface that is not completely flat makes uneven contact,
and will be burnished in only part of its contact area.
Figure 9-3 shows what a surface would look like if only the
inner area had been making contact, because that is where
burnishing has taken place. The outer area has no marks at
all, indicating there has been no contact there.
Burnished
Area
Figure 9-3 Burnished Area Indicates
Uneven Mating Surfaces
As shown in Figure 9-3 the burnished area appears only around
the mounting stud area, and not at the edges. This is evidence
of “crowning” illustrated in Figure 9-4.
To get some idea of the extent of the problem, put a straight
edge along the surface of the stack element being inspected.
Because the stack element as shown in Figure 9-4 is crowned at
the center, there are gaps along the outer edge of the element.
Center Depression
An element’s surface may also be depressed in the mounting
stud area. See Figure 9-5. This element would make contact
only at the outer edge.
Crown

Edge
Gap

Again, a straight edge placed along the mating surface of the

stack element gives an idea of the extent of the problem. A
gap visible beneath the straight edge near the center of the
Figure 9-5 Center Depression
element shows how deep the depression is.
82
Section 9 Maintenance
Surfaces with Uneven Contact, continued
Corrosion
Corrosion is another factor to consider in determining overall
system performance. In time, corrosion can build up on stack
mating surfaces, and contribute to a loss in performance. Evidence of corrosion includes discolored mating surfaces or surfaces that are encrusted with hard deposits.
NOTE
To extend equipment life and to keep performance levels high,
minimize the system’s exposure to any corrosive source.
83
Ultra 15 kHz Assembly System User’s Manual
Reconditioning Stack Components
Overview
Stack components need reconditioning when mating surfaces
become uneven or corroded. These conditions cause poor
contact between the mating surfaces. This wastes power,
makes tuning of the acoustic stack difficult, can cause heat
damage to the transducer, and can contribute to a higher
system noise level.
NOTE
Before deciding to recondition mating surfaces on your
own, consider calling Dukane Corporation’s Tooling
Support to discuss the situation. This is especially true if the
mating surfaces are uneven because machining of the
components may be required. Factory personnel can offer
their skills and experience for your situation.
See Section 11 for a list of Dukance contacts.
Reconditioning the Mating Surfaces
Machining
Instruction to machine the stack components is beyond the
scope of this User’s Manual. Please call Dukane’s Tooling
Support team for machining information. See Section 11 for a
list of Dukane contacts.
Manual Resurfacing
Follow the steps below to manually resurface the stack components’ mating surfaces.
1. Disassemble the acoustic stack, and wipe all the mating
surfaces with a clean cloth or paper towel.
2. Examine all of the surfaces. If any is corroded (discolored
or coated with hard deposits), it should be reconditioned.
Continued
84
Section 9 Maintenance
Resurfacing Components, continued
3. If the surfaces appear as if they are in good condition, go
to Step 11.
4. If necessary, remove the mounting studs.
5. Tape a clean sheet of #400 grit (or finer) emery cloth to a
clean, smooth, flat surface (such as a piece of plate glass)
so the grit side is up.
6. Hold the stack component with one hand as shown in
Figure 9-6. This view shows the thumb covering one of the
three spanner wrench holes.
Without applying any downward pressure, carefully stroke
the part IN ONE DIRECTION across the emery cloth. (The
component’s weight alone will be enough as the part is
moved.) Complete a second stroke across the cloth just
like the first one.
Figure 9-6 Manual Resurfacing
CAUTION
Use extreme care to keep the part level when
moving it across the emery cloth. Do not tilt it.
An uneven mating surface could leave the
welding system inoperative.
7. Keep the element’s surface flat against the emery cloth,
and turn it 120° (one-third of a complete rotation) so the
thumb covers the next spanner wrench hole. Again, move
the part twice across the emery cloth as outlined in Step 6.
8. Give the part a final one-third turn, and repeat the two
strokes described in Step 6.
CAUTION
It is important to perform only 2 strokes each
time the component is rotated 120°. Performing more or fewer strokes affects whether the
surface remains flat. If the surface loses its perpendicularity
in relationship to the component’s centering axis, the welding system may become inoperative.
85
Ultra 15 kHz Assembly System User’s Manual
Resurfacing Components, continued
9. Reexamine the mating surfaces, and repeat Steps 6 – 8 until
the corrosion has been removed. Typically this takes no more
than three complete rotations of the component.
10. Mounting studs need to be reinserted, but before that is done
get proper thread engagement by:
• inspecting and cleaning the stud,
• cleaning the threaded hole with a cloth, and
• threading the stud into the hole, and tightening it to the
torque specifications shown in Table 9-1 on the next page.
NOTE
Threads may deform if the studs are overtightened. Removing
a stud that has been overtightened could damage the threads
in the horn.
If this should happen, retap the horn threads, and replace the
stud with a new one.
11. Reassemble the stack and install it using the procedure
shown in Section 5.
12. Complete the Operational Stack Test shown in Section 7.
86
Section 9 Maintenance
Torque Values
Overview
Apply torque values from the three categories listed below
when reassembling stack components:
• Stack assembly values (below)
• Booster and horn stud values (Table 9–1)
• Tip torque values (Table 9–2)
CAUTION
Do not overtighten stack components.
Overtightening may cause studs to
loosen, causing the generator to go into
an OVERLOAD condition.
Stack Assembly Torque Value
A 15 kHz acoustic stack consists of a transducer, a booster,
and a horn. Use the following torque value when assembling
the stack.
• 250 inch-pounds
• 20.8 foot-pounds
• 28.2 Newton-meters.
Booster and Horn Stud Torque Values
Use the torque values shown in Table 9-1 when installing studs
into either a booster or horn to be used in a 15 kHz stack.

Press/Thruster Maintenance
NOTE
Several factors determine how often the equipment needs
attention. The material being welded, duty cycle and the
manufacturing environment are primary factors in deciding
how frequently inspections and maintenance should occur.
Daily Inspection
1. Check the entire unit for oil and dirt accumulation, and
wipe any away.
2. Inspect the air filter bowl and filter element on the rear of
the press. Clean the filter bowl and clean or replace the
filter element when needed.
3. Inspect wires and cables for signs of wear. Reroute them
if necessary to eliminate the problem.
Six-Month Periodic Maintenance
1. Disconnect the Ultra-Com and generator AC power cords
from the AC receptacles.
2. Remove the left and right press housing covers.
3. Make sure all socket head cap screws are tight.
4. Check the air cylinder mounting to make sure it is secure.
5. Wipe away oil and dirt accumulation from the entire unit.
6. Inspect the transducer housing and air exhaust opening for
signs of dirt or oil. Wipe away any accumulations.
NOTE
Because the pressurized air going to the press/thruster is
specified as free of moisture and oil, there should be no oil
accumulation on the transducer. If oil is present on the transducer housing, it means oil is coming through the air line.
Eliminate oil and moisture in the air line.
One suggestion: Try routing the air line for the press through
an “oil mist reclassifier”.

7. Check the thruster slide for smooth downward operation.
Wipe away any accumulated grease, but do not apply any
solvents. If movement is not smooth, apply a small amount of
30 weight oil to a rag, and wipe the two slide rails with it.
8. Ensure that all wires and cable connections for the entire
system are secure. If cables or wires show wear, reroute them
to eliminate the problem.
9. Replace the left and right press housing covers.
10. Reconnect the Ultra-Com and generator AC power cords to
their respective AC receptacles.

Dukane ISO
ISO CERTIFICATION
Dukane chose to become ISO 9001 certified in
order to demonstrate to our customers our continuing commitment to being a quality vendor.
By passing its audit, Dukane can assure you
that we have in place a well–defined and systematic approach to quality design, manufacturing, delivery and service. This certificate reinforces Dukane's status as a quality vendor of
technology and products.
To achieve ISO 9001 certification, you must
prove to one of the quality system registrar
groups that you meet three requirements:
1. Leadership
2. Involvement
3. Quality in Line Organizations and Quality
System Infrastructure.
The ISO 9001 standard establishes a minimum
requirement for these requirements and starts
transitioning the company from a traditional inspection–oriented quality system to one based
on partnership for continuous improvement. This
concept is key in that Dukane no longer focuses
on inspection, but on individual processes.
Dukane's quality management system is based
on the following three objectives:
1. Customer oriented quality. The aim is to
improve customer satisfaction.
2. Quality is determined by people. The aim
is to improve the internal organization and
cooperation between staff members.
3. Quality is a continuous improvement. The
aim is to continuously improve the internal
organization and the competitive position.
