5) Never remove or bypass the equip-
ment power cord ground. Verify the equipment is grounded in accor-
dance with all applicable local and national electrical safety codes. If none exist, use International Electric Code (IEC) 950.
READ INSTRUCTIONS.
Read the instruction manual before
installing and using the equipment.
2
EQUIPMENT DAMAGE
POSSIBLE.
1) Do not plug in the power cord without first verifying the equipment is OFF and the cord input voltage is the same as required by the machine or serious damage may result.
2) Always verity both the pinion and wheels are fully engaged before apply-
ing power or equipment damage may occur.
3) Do not leave the equipment
unattended.
4) Remove from the worksite and store in a safe location when not in use.
FALLING EQUIPMENT
can cause serious
personal injury and
equipment damage.
Faulty or careless user installation is possible. As a result, never stand or walk
underneath equipment.
MOVING PARTS can
cause serious injury.
1) Never try to stop the pinion from mov-
ing except by removing power or by using the STOP control.
2) Do not remove any protective panels, covers or guards and operate equip-
ment.
HIGH FREQUENCY WARNINGS
SPECIAL PRECAUTIONS ARE REQUIRED WHEN USING PLASMA,
TIG OR ANY WELDING PROCESS THAT USES HIGH FREQUENCY
TO STRIKE AN ARC.
WARNING: HIGH FREQUENCY CAN EFFECT MACHINE OPERATION AND THEREFORE, WELD QUALITY.
Read the precautions below before installing and using the equipment.
PRECAUTIONS:
1) Some plasma or welding cables are strong sources of high frequency
interference. NEVER lay a plasma or welding cable across the controls of the machine.
2)
Always physically separate the plasma or welding cable leads from the machine cables. For example, the plasma or welding cable leads should NEVER be bundled with a pendant cable or the machine power cord. Maxi-
mize the separation between any machine cables and the plasma or welding cables.
3) Strictly follow the grounding procedures specified for the plasma or welding unit. NOTE: Some plasma and welding units produce exceptionally large amounts of high frequency noise. They may require a grounding rod be driven into the earth within six feet (2 meters) of the plasma or welding unit to become compatible with an automatic cutting or welding process.
4) If the high frequency is produced using a spark gap, adjust the points so the gap is as small as possible. The larger the gap, the higher the voltage and the higher the interference.
5) Some plasma or welding units will inject high frequency interference into the AC power line. Use separate power line branches whenever possible to power the plasma or welding source and the machine. Do not plug them into the same outlet box.
6) High frequency noise may enter the machine through the plasma or welding supply remote contactor leads. Some plasma and welding sources can produce noise spikes of up to several thousand volts. These sources are not compatible with automated cutting and welding equipment. It is recom-
mended that the remote contactor leads on these plasma or welding sources not be connected to the machine. An alternate solution is to purchase a separate remote contactor isolation box.

INTRODUCTION
The Modular Drive System is the only product in the industry that allows the user to custom configure one
machine for various applications. The system consists of drives, plug-in control modules and carriages that
are easily assembled. The modular design allows the operator to quickly upgrade or reconfigure the machine
for straight line cutting and welding, stitch welding or weave welding. The system will run in any position using
Aluminum Rigid Rail, Aluminum Semi-Flex Rail [with a minimum radius of 15' (4.57 m)], Bent Rigid Rail or HiFlex Rail [with a minimum radius of 40" (1 m)].
The straight line cutting and welding configuration consists of a carriage, master drive, racking group and
control module. The optional MDS-1060-10 Remote Control Cable can be used to remote the control module.
A number of straight line control modules are available. The MDS-1002 Straight Line Module provides
simple direction and speed control for continuous cutting or welding. The MDS-1003 Stitch Module provides
a straight line and stitch welding mode with skip time, weld time and crater/puddle buildup time. The MDS1004 Programmable Stitch Module provides digital display of all stitch welding parameters. The MDS-1004
Stitch Module has closed position feedback so all distances are set in inches or mm as opposed to time and
are repeatable. The MDS-1055 Universal Limit Kit adds cycler, stop at limit and rapid return functions to the
MDS-1002 and MDS-1003 modules. The MDS-1004 Programmable Module has built in stop at limit and rapid
return modes. For more features, see the appropriate pages on each of the modules.
The Master Drive is rated at 60 lbs (27 kg) vertical load. (International Robotics Standards Rating)** The
machine is equipped with overload protection.
STANDARD FEATURES:
The Master Drive Unit incorporates the following standard internal features:
•
High torque, low inertia motor for precise stops and starts.
•
Dedicated fail-safe brake with three times the stopping and holding power of the motor.
•
Motor overload protection which turns off the motor and engages the brake when excessive load is
placed on the machine.
•
Closed loop speed control for adjustable and repeatable control of critical welding or cutting parameters.
•
Closed loop position control to prevent position creep when the machine stops to perform an operation
such as crater fill at the end of a stitch weld.
**The International Robotics Standards Rating requires a minimum of 2:1 continuous-duty safety margin on
all power train and electronics components.

SETUP
1) WHEEL ADJUSTMENT AND ALIGNMENT
Always check for proper carriage wheel adjustment before using the machine. Turn the wheel engagement knob (A) on the
side of the carriage until the wheels are fully moved towards the
center of the carriage (engaged). Then rotate the master drive
clutch knob (B) fully counter clockwise to disengage the drive
pinion. Slide the carriage onto the end of a track. The wheels
should slide into the track V-grooves and the carriage will move
smoothly along the track if the wheels are properly aligned.
The wheels along one side of the carriage have stainless steel shim washers
(C) underneath. These wheels are adjustable. Readjust these wheels (if necessary) by rotating the hex bolt (D) with a 1/2" wrench.
B
A
C
Grasp the sides of the carriage. The wheels are too loose if it is possible to move
the carriage from side to side or up and down. Use a finger to keep one of the
adjustable wheels from rotating as the carriage is manually pushed along the
track. The wheels are adjusted too tight if firm finger pressure is not enough to
prevent wheel rotation. Repeat the process for the other adjustable wheel.
2) POSITIONING THE MACHINE ON THE TRACK
D
Position the rail using magnet plates or vacuum cups. Wipe the track grooves free of weld splatter and
other debris. This will prevent binding and premature rail and wheel wear. Lubricate the rack using a dry
spray, if desired, for extended track life.
Turn the wheel engagement knob (A) on the side of the carriage fully counter clockwise to disengage the
wheels. Then rotate the Master Drive clutch knob (B) fully counter clockwise to disengage the drive pinion.
The carriage can now be placed anywhere on the track. Turn the wheel engagement knob (A) clockwise
to engage the wheels firmly in the V-grooves. Verify all four wheels are in the grooves. Manually move
the carriage along the track to verify the motion is smooth and the wheel alignment is correct. Rotate the
Master Drive clutch knob (B) fully clockwise while gently rocking the machine forward and backward to
fully engage the drive pinion. The rocking motion is necessary to help insure proper gear mesh.
3) REMOTE CONTACTOR WIRING
Connect the remote weld contactor to the welding source as shown below:
Pins A and B .................connection for Output #1
Pins C and D ................connection for Output #2
4) GUN AND TORCH SETUP
For welding, insert the welding gun into the all-position clamp on the rack. Adjust the clamp, the clamp
block and the rack to position the gun for welding. Connect the weld contactor connector to the rear of
the main drive unit. Route the welding cable and weld contactor wires through the cable anchor clamp.
For cutting, insert the cutting torch into the torchholder on the rack. Adjust the torchholder, the clamp block
and the rack to position the torch for cutting. Connect the hose assembly to the manifold and the cutting
torch. The manifold acts as a strain relief on the supply hoses as well as a quick shut-off valve for the
gases. Once the torch valves are adjusted, the manifold eliminates the need for continuous adjustments
and keeps the supply lines from dragging the torch out of position.
5) MACHINE OPERATION
Turn the main power ON at the power entry box. Set parameters on control module in use.

CARRIAGE TRAVEL SWITCH: Provides FORWARD/STOP/REVERSE direction control.
Stop at limit in direction of travel & Cycle between limits can be controlled with
the installation of the MDS-1055 Universal Limit Kit. (Ref to pg. 37)
DIGITAL READOUT: The display is dual function.
a) PRESET SPEED - Displayed when the CARRIAGE TRAVEL SWITCH is OFF or motion is halted by a motor overload condition.
b) MEASURED SPEED - Displayed when power is applied to the motor.
(This will be the same as the Preset Speed.)
Factory settings of 120 Volt machines are set to in/min, 240 and 42 Volt machines are set cm/min.
WELD CONTACT: Opens/closes a pair of independent 1 Amp contacts (pins A & B and C & D) at the weld
contactor receptacle.
NOTE: A safety interlock will automatically open the weld contacts if the motor overload protection halts machine motion. Clear the overload by turning the carriage travel switch to OFF. Resetting the overload
fault will not cause the contacts to automatically reclose. Use the weld contact switch to restart the

1) The machine stops moving for the selected time to perform Puddle Buildup. (PIERCE WHEN PLASMA CUTTING)
2) The machine welds at the selected welding speed for the time selected using the Weld Time control.
3) The machine stops moving for the selected time to perform Crater Fill.
4) The machine turns off the welder and moves at maximum speed to where the next weld needs performed. This location is determined by setting a Skip Time control.
WELD TIME: This control functions only when the mode switch is set to Stitch. Weld time sets a weld
length time from 1-50 seconds. This corresponds to a weld length of approximately 0.03-100 inches (0.82540 mm). NOTE: The operator must manually enable the weld contactor by turning on the Weld Contact
or the welder will never cycle on and off.
SKIP TIME: This control functions only when the mode switch is set to Stitch. Skip time sets how long the
machine travels between welds (0.3-15 seconds). This corresponds with a skip length of approximately 0.630 inches (15-762 mm). The machine always moves between welds at maximum speed.
PUDDLE BUILDUP / CRATER FILL TIME: This control functions only when the mode switch is set to
Stitch. Puddle Buildup/Crater Fill Time sets the time the machine is stopped at the beginning and end of
every weld (0-1.5 sec).

FEATURES
Extra Contactor Output
•
Each stitch setting is displayed while being set. This allows each setting to be exactly set each time
a job is set up.
•
Closed loop encoder feedback is employed to ensure the traveled distances match the set distances.
•
The module provides an extra contactor output. This output and the output on the Modular Drive can
be disabled or enabled independently.
•
The module will stop the machine or return it to start after a preset number of welds. This eliminates
the need for external limit switches.
•
This unit can return past the start location to allow for work piece changes. One button will start the
whole welding procedure.
•
Stitch welds stopped in mid-job can be restarted without interrupting the weld pattern.
•
Puddle-buildup and Crater-fill timers are independent.

MDS-1005-DIAL WEAVER CONTROL MODULE
The MDS-1005 Dial Weaver Control Module provides weave welding control functions with 3 turn digital dial
pots for the weave speed, weave amplitude, dwell left and right. The addition of the dial pots allows for precise and repeatable setting of all parameters. The dial pots also enable repeatable parameter settings from
machine to machine. All dials vary from 0-300 which corresponds to the setting the parameter from 0 to its
MAX value. For example, a 300 setting for weave amplitude corresponds to 2" of weave amplitude which is
its max value. The DIGITAL READOUT provided for the tractor speed displays in either inches per minute or
centimeters per minute directly.

WEAVER CONTROL MODULES (CONT’D.)
AMPLITUDE (WEAVE): Continuously adjustable up to a 2" (51 mm) maximum weaver stroke.
CARRIAGE TRAVEL SWITCH: Provides FORWARD/STOP/REVERSE direction control.
DIGITAL READOUT: Three tractor display modes exist.
a)PRESET SPEED - Displayed when the CARRIAGE TRAVEL SWITCH is OFF or motion is
halted by a motor overload condition.
b) CONTINUOUSLY MEASURED SPEED - Displayed when the MODE SELECTOR SWITCH
setting is RUN or NO WEAVE. (This will be the same as the Preset Speed.)
c) SAMPLED SPEED - The tractor motion alternates between moving at the Preset Speed and
stopping when the MODE SELECTOR SWITCH is set to STEP or STOP ON DWELL. This is
referred to as “stepping” the tractor. To avoid having the display continuously fluctuate between
the zero speed and the actual speed, the readout measures the travel speed near the end
of each tractor step. This speed is then displayed until another sample is taken at the end of
the next tractor step. This provides a stable display of the measured travel speed. (This will
be the same as the Preset Speed.)
Factory settings of 120 Volt machines are set to in/min, 240 and 42 Volt machines are set cm/min.
LEFT AND RIGHT DWELL: The left and right dwell controls have a 0-3 second adjustment range.
MODE SELECTOR SWITCH: Four welding modes are available.
1) RUN - In this mode, power to the drive unit is always on
and the machine travels continuously both during weave
and dwell. Weave speed and dwell time both affect the
weave pattern.
2) STEP - The unit travels only during dwell and stops during
the weaver cross stroke. Changing weave speed does not
effect the weld pattern-dwell time does.
3) TRACTOR STOP ON DWELL - The tractor travels during
the weave stroke; the tractor and weaver stop during dwell.
4) NO WEAVE - In this mode oscillation is stopped. Only the
tractor is powered. This mode is used for stringer passes.

4
SPEED CONTROL (TRACTOR): Sets the tractor speed from 2-120 in/min (5.1-304.8 cm/min).
START/STOP: This enables/disables all tractor and weaver motion.
STEERING: The three-turn steering knob has a +/- 2" (51 mm) range.
WEAVE SPEED CONTROL: Sets the weave speed from 0-100 in/min (0-254 cm/min).
WELD CONTACT: Opens/closes a pair of independent 1 Amp contacts (pins A & B and C & D) at the weld
contactor receptacle.
NOTE: A safety interlock will automatically open the weld contacts if the motor overload
protection halts machine motion. Clear the overload by turning the carriage travel
switch to off. Resetting the overload fault will not cause the contacts to automatically
reclose. Use the weld contact switch to restart the welder after clearing the overload.

LINEAR WEAVER SETUP
1) WEAVER CONTROL MODULE AND LINEAR WEAVER INSTALLATION
The Weaver Control Module plugs into the top of the Master Drive Unit. Use a flat head screw driver to
firmly secure the four corners of the module.
Place the Linear Weaver on a flat surface, connector side up. Remove connector cover plate from MPD-1000.
Loosen, but do not remove, the bolts that hold the Master Drive Module to the carriage. Plug the Master Drive
Module into the Linear Weaver. The connectors should fit together easily and do not need forced. Attach
the Linear Weaver to the carriage using the two weaver mounting bolts. DO NOT SUBSTITUTE LONGER
BOLTS. Retighten the bolts that hold the Master Drive Unit to the carriage.
2) CROSSARM WHEEL ADJUSTMENT AND ALIGNMENT
Always check the crossarm wheel adjustment before using the machine. The
wheels are too loose and need adjustment if the crossarm can move up and
down. Normal gear backlash will permit crossarm side to side movement of
approximately 0.02" (0.5 mm).
If the wheels need adjustment, remove the left and right weaver end covers. The
two top wheels are adjustable. Loosen the hex bolt (A) until the adjustable bushing
(B) can be rotated. Correct the wheel alignment by rotating adjustable bushing (B).
B
A
Check for proper alignment by using a finger to keep one of the wheels from
rotating while manually moving the crossarm. The wheels are adjusted too tight if
firm finger pressure is not enough to prevent wheel rotation. Once aligned, hold the
adjustment bushing (B) still while tightening the hex bolt (A). Recheck alignment.
3) REALIGNING THE CROSSARM
(includes crossarm INSTALLATION and REMOVAL)
Rotate the clutch knob (C) fully counterclockwise. This
disengages the drive pinion from the rack. Remove
the two socket head screws from the crossarm (D). The
crossarm may be removed from or installed into the
Linear Weaver at this time.
Turn on the AC power. Rotate the four-turn steering
control knob and the weave speed knob on the Weaver
Control Module fully clockwise. Turn the start/stop
switch to START. Set the mode selector switch to NO
WEAVE. Align the crossarm (D) so that 1 7/8" (48 mm)
of the crossarm protrudes from the left side of the Linear
Weaver. To insure proper gear mesh, gently rock the
crossarm back and forth about 1/16" (2 mm) while
engaging the pinion using the clutch knob (C).
D
LEFT SIDE
C
CAUTION: IMPROPER GEAR
MESH MAY CAUSE PINION, RACK,
OR LINEAR WEAVER DAMAGE.
Set the weave amplitude to maximum. Use the steering knob on the control module to move the crossarm to
both the extreme left and the extreme right. Perform measurements to determine if The crossarm is installed
too far left or too far right. Repeat the crossarm realigning procedure changing the 1 7/8" (48 mm) dimension
as required. Reinstall the two crossarm screws.

4) REMOTE CONTACTOR WIRING
Connect the remote weld contactor on the Master Drive to the welding source as shown below.
Pins A and B . ..................connection for Output #1
Pins C and D....................connection for Output #2
5) GUN AND SETUP
For welding, insert the welding gun into the all-position clamp on the rack. Adjust the clamp, the clamp
block and the rack to position the gun for welding. Connect the weld contactor connector to the rear of the
Master Drive Unit. Route the welding cable and weld contactor wires through the cable anchor clamp. Turn
on the AC power. Use the steering knob on the control module to move the crossarm to both the extreme
left and then the extreme right. Turn on the oscillator, at the same time, with the controls set to maximum
weave width. Readjust the crossarm or the gun if the racking fixture hits the case during operation.
6) MACHINE OPERATION
Turn the main power ON at the power entry box. Set the following parameters using the MDS-1005
Control Module (Ref. pg. 18 for illustration):
Weld Mode Selector Switch
Tractor Speed Control
Steering Control
Weave Amplitude
Weave Speed
Left and Right Dwells
The Start/Stop control will turn on the weaver. To start welding, push the weld contactor switch “ON” (momentarily) which will turn on the wire feeder/weld current. Use the carriage travel switch to select a forward
or reverse carriage travel direction.
CAUTION: The Speed Control Card in the Linear Weaver is NOT interchangeable with the speed card in
the Master Drive or Pendulum Weaver.

WPD-2100 PENDULUM WEAVER II
INTRODUCTION
The Pendulum Weaver and Weaver Control Module add a pendulum-type weaving motion to the
Modular Drive System. The Pendulum Weaver is particularly useful for weaving fillet welds in a corner
joint. The weaver motor box is mounted to the front of the carriage using standard racks and rackholders.
FEATURES
• High torque, low inertia motor for precise starts and stops.
• Heavy duty planetary gear box with powerful output shaft for rotating
welding gun and attachments for the gun.
• High speed pendulum motion with independent control of right and left dwell times.
• High motor gearing ratio, that prevents the welding gun from moving by backdriving the gear train when power is off.
• Closed loop speed control for adjustable and repeatable control of critical welding or cutting parameters.
• Closed loop position control to prevent drift from the center position.
• Gun mounting group with adjustable racking block for accurate positioning of the gun.
• Weld Contactor ON/OFF switch.
28
PENDULUM WEAVER II SETUP
INSTALLATION
The Weaver Control Module plugs into the Master Drive Unit. Use a flat blade screwdriver to firmly
secure the four corners of the module.
Remove connector cover plate from MPD-1000. Plug the Pendulum Weaver Electronics box into the
front end of the Master Drive Unit. Secure the box to the drive unit by using the four captive screws
on the electronics box.
Bolt the mounting plate onto the front of the carriage, below the electronics box, and bolt the rackholder onto the mounting plate. Insert the 14" (355 mm) rack through it.
Several different arrangements can be used to mount the gearbox on the rack and to position the
welding gun. One recommended assembly method is shown below: bolt the racks, gearbox, and
clamps together as shown in the diagram.
Finally connect the gearbox to the electronics box using the cable supplied, with 6-pin connectors on
each end.
29
SETUP AND ALIGNMENT
Attach the rail parallel to the weld joint, with magnet bars or vacuum cups. Position the drive carriage on the rail - see Modular Drive instructions if necessary.
Insert the welding gun into the clamp on the pendulum weaver. Adjust the racks and clamps to align
the welding gun tip with the weld joint, and tighten firmly in place.
IMPORTANT!
When the welding gun is clamped in place with the nozzle pointing into the weld groove, the centerline of the wire must pass through the axis of the gearbox output shaft, as shown in Figure A, which
is a view looking along the shaft. Figure B shows the side view of the same.
For a fillet weld, the nozzle will be at a 450 angle as shown in Figure C, and will swing equally in
both directions.

MDS-1055 UNIVERSAL LIMIT KIT
The MDS-1055 Universal Limit Kit is an accessory that installs between the Master Drive Unit and any of
the three control modules: the *MDS-1002 Straightline, the MDS-1003 Stitch and the MDS-1005 Weaver
Control Module. This limit kit adds the ability to CYCLE between limits, STOP AT LIMIT, or RAPID RETURN.
All existing functions of the control modules are maintained.
CYCLE MODES:
a) CYCLE - Cycles between two limits. Limit contact does not turn off the weld contactor.
b) STOP AT LIMIT - Limit contact in the direction of travel set by the control module Carriage Travel
Switch will stop motion and turn off the weld contactor. The Carriage Travel Switch will reverse
the travel direction and start motion away from the contacted limit. The weld contactor will not
automatically turn back on when the machine exits a limit.
c) RAPID RETURN - The machine will run at the preset welding speed in the direction set by the
Carriage Travel Switch on the control module until it hits a limit. When this limit is hit, the machine
will turn off the weld contactor, reverse direction, and travel at full speed to the opposite limit. Upon
reaching the limit, the machine stops.
*FMD-1055 For use on Hi-Flex Rail Only.

CAS-20__ AUTOMATIC HEIGHT CONTROL
CAS-2050 AUTOMATIC HEIGHT CONTROL / Linear Weaver
The CAS-2050 is an Automatic Height Control (AHC) for the Linear Weaver (WPD-1100) that controls
the welding tip to work distance and maintains a constant weld current, helping to provide uniform
weld penetration. The CAS-2050 senses the actual weld current, compares this value to the set point,
and raises or lowers the welding gun accordingly.
CAS-2060 AUTOMATIC HEIGHT CONTROL / Pendulum Weaver
The CAS-2060 is an Automatic Height Control (AHC) for the Pendulum Weaver (WPD-2100) that
controls the welding tip to work distance and maintains a constant weld current, helping to provide
uniform weld penetration. AHC senses the actual weld current, compares this value to the set point,
and raises or lowers the welding gun accordingly. It features a built-in time delay after the arc is
struck, and automatically shuts off when the current drops too low (generally below 60 amps).

ALUMINUM RIGID RAIL
ALUMINUM RIGID RAIL is a high quality alloy, rigid section made to the machine tool tolerance shown in
the sectional view below. The carriage drive pinion meshes with a machined gear rack that is mounted on
the rail. The wheels of the carriage travel in opposed grooves at either side of the rail, locking the carriage
to the rail. Heavy duty [H.D.] aluminum four-legged rigid rail is supplied in two lengths: ARR-1080 [93-1/2"
(2.37 m)] called 8' (2.37 m) rail and ARR-1085 [46-1/2" (1.18 m)] called 4' (1.18 m) rail - see insert below.
Extra heavy duty aluminum four-legged rigid rail: ARR-1250 [93-1/2' (2-37 m)] called 8' (2.37 m) rail and
ARR-1200 [46-1/2" (1.18 m)] called 4' (1.18 m) rail, is also available.
NOTE: 8' Rails accept up to 8 supports, 4' Rails accept up to 4 supports.
RAIL FOR LONGER SPANS:
When unsupported rail paths longer than 93-1/2" (2.37 m) nominal 8' (2.37 m) rail are required, multiple
sections of standard rail are mounted on plate, channel or box sections.

AFR-3000 SEMI-FLEX RAIL replaces the old AFR-1000, 1010, 1020 and the later AFR-2000 rails. All
the rack-mounting holes on the AFR-3000 Semi-Flex Rail are slotted so that the rack can slide along
the rail. The length of the slots has been increased so that the rails can now be leapfrogged around a
complete circle. The tension of the screws holding the rack on the rail is adjusted so that the rack can
be moved along the rail with the AFR-2001 Rack-Adjusting Tool.
NOTE: Use at least four attachments (magnets or vacuum cups) on each SEMI-FLEX RAIL.

STANDARD MAGNET ASSEMBLIES
MAGNET PLATE ASSEMBLIES mount ARR rail quickly and conveniently right on the work surface. Magnets
cannot exert maximum pull on dirty material. Remove excessive paint, scale and rust from the area on
which the magnets will be placed.
KEEP MAGNETS CLEAN - before positioning, wipe off magnetic particles which adhere to the poles.
For MAXIMUM HOLDING POWER on swivel magnets, press down on top of each side of magnet.... then
rotate until it holds firmly. The magnet will retain its magnetism indefinitely - to preserve the magnet casing,
keep torch 4" (101 mm) away from magnets when burning/welding. Use various thicknesses of keepers to
decrease the magnetic pull when required.
R.E. On/Off Magnets
The New, Bug-O/ Mag-switch, Switchable On/Off
Rare-Earth magnet assembly provides for quick rail
positioning without fighting the magnet. The lighter
weight, at just 1.7 lb. (.77 kg), less than all other
magnet assemblies, improves handling. 200 lb (90
kg) holding capacity.
*All XXX-2010-HH are “High Heat” models and are rated
at 180°C (356°F) for high temperature applications.
Swivel Magnets
Magnet bar, swivel with release; recommended
for all applications, combines maximum strength
and versatility. This assembly holds up to 250 lbs.
(113 kg) on a flat, clean steel surface.
Short Swivel Magnets
Magnet bar, short; compact for positioning in hardto-reach or restricted areas. This assembly holds
up to 200 lbs. (91 kg) on a flat, clean steel surface.

The Modular Drive System allows the user to mix and match components to custom build a machine for
an application. The resulting ability to replace and remove individual components while troubleshooting significantly reduces the time and effort required to troubleshoot the system. The recommended
troubleshooting procedure is as follows:
1) Verify that there are no loose electrical or mechanical connections.
2) Verify that the welding power source is properly grounded and its ground clamp is attached to
the workpiece.
3) Ensure the High Frequency Warnings in the front of this IPM are not being violated.
4) When possible, swap out each component in the system one at a time with a known good
component. For example, replace the Control Module on a defective machine with the Control
Module from a working machine. Often, this will pinpoint the defective component quickly. If the
defective component is a Weaver Drive or a Master Drive, troubleshoot the drive to a circuit
board level using step 5 and/or 6 below.
5) Remove all attached components. This includes the Remote Control Cable and Universal Limit
Kit. All attached components are removed to limit the number of components affecting the operation
and complexity of the system. Assemble a base system composed of a Control Module and
a Master Drive. Test the base system. If the base system does not work, troubleshoot the base
system to a circuit board level using the Base System Test Procedure. If possible, test the
Control Module by swapping it with a known good Module.
6) If the system had a Weaver Drive, install it and retest the system. If the system does not work,
troubleshoot the system to a circuit board level using the Base System Test Procedure. NOTE: The weaver failure can result from a faulty Control Module, Master Drive or Weaver
Drive because they all interact. Use the Base System Test Procedure to find the faulty component.
7) Some components require special attention when troubleshooting and have their own trouble
shooting section. These components are:
Universal Limit Kit (MDS-1055)
Perform any relevant troubleshooting section as required before proceeding to the base system
test procedure. The special troubleshooting sections are located after the Base System Test
Procedure.
8) Finish installing the components one at a time. Test the system after each installation in order
to identify the problem components.

Install one voltmeter lead on TP4 and the other lead on TP5. Turn
on the main power. Set the control module for continuous forward
tractor motion. If the control module has any type of motion enable
switch, turn it to enable. Rotate the tractor speed control knob while
observing the voltmeter output. It is possible to vary this voltage
between 0 and 8 Volts DC using a good
control module.
a) If the voltage does not vary, replace the control module card.
b) If the voltage does vary, turn the machine OFF and then ON
using the main power switch. Observe LED L5. L5 should light
for a moment or two during power-up while safety circuits hold
the tractor OFF until full power is reached. L5 should then turn
off indicating power has been applied to the motor and motion
should start.
1) If the L5 never lights, replace the speed card.
2) If the L5 turns on, turns off, and then turns on again, check for
shorted motor connections. If none are found, replace the speed
card.
3) If the L5 turns on and then stays on, check that the control
module is set up as defined above and retest 2F. A second failure
indicates a bad speed card.
4) If L5 turns on and then off and the motor doesn’t start turning,

UNIVERSAL LIMIT KIT TROUBLESHOOTING
This Troubleshooting section details troubleshooting the Universal Limit Kit. See the Modular Drive System
Troubleshooting Guide for troubleshooting all other components.
Recommended Troubleshooting Procedure:
1) If using the Universal Limit Kit with the MDS-1001 Straight Module, the CYCLE SELECTION switch on the Control Module must be in the BASIC FORWARD/REVERSE position for the machine to operate property.
2) Perform steps 1 through 6 in the Modular System Troubleshooting Guide, The Master Drive, Control Module and Weaver Drive must be functioning correctly before proceeding.
3) Check for loose or damaged wires both internal and external to the Universal Limit Kit.
4) If the machine does not move at all, measure the voltage across each limit switch on the PC board while cycling the switch on and off. The voltage should toggle between 0 and 12V DC. If it does not, the limit switch or limit switch wiring is damaged.
CAUTION: If using the MDS-1001 Straight Module with the Universal Limit Kit, the CYCLE SELECTION switch on the Control Module must be in the BASIC FORWARD/REVERSE position or the machine may not move.
5) If the machine turns around, stops, or starts unexpectedly, the Universal Limit Kit may be picking up RF noise from the welder. Move all of the welder cables away from the Universal Limit Kit, the limit switch wires and the Control Module.
6) If the previous steps did not fix the Universal Limit Kit, the PCB-1030 card is probably defective. Replace the card.
