GENERAL INFORMATION
TRANSARC 170i
2. Wear approved safety glasses. Side shields recommended.
WARNING
ARC RAYS can burn eyes and skin; NOISE
can damage hearing.
Arc rays from the welding process produce
intense heat and strong ultraviolet rays
that can burn eyes and skin. Noise from
some processes can damage hearing.
1. Use a Welding Helmet or Welding Faceshield fitted
with a proper shade of filter (see ANSI Z49.1 and
AS 1674 listed in Safety Standards) to protect your
face and eyes when welding or watching.
3. Use protective screens or barriers to protect others
from flash and glare; warn others not to watch the
arc.
4. Wear protective clothing made from durable,
flame-resistant material (wool and leather) and
foot protection.
5. Use approved ear plugs or ear muffs if noise level

3. Remove all flammables within 35 ft (10.7 m) of the
welding arc. If this is not possible, tightly cover
them with approved covers.
WARNING
4. Be alert that welding sparks and hot materials from
welding can easily go through small cracks and
openings to adjacent areas.
FUMES AND GASES can be hazardous to
your health.
Welding produces fumes and gases.
Breathing these fumes and gases can be
hazardous to your health.
5. Watch for fire, and keep a fire extinguisher
nearby.
6. Be aware that welding on a ceiling, floor, bulkhead,
or partition can cause fire on the hidden side.
1. Keep your head out of the fumes. Do not breath
the fumes.
7. Do not weld on closed containers such as tanks
or drums.
2. If inside, ventilate the area and/or use exhaust at
the arc to remove welding fumes and gases.
8. Connect work cable to the work as close to the
welding area as practical to prevent welding current from travelling long, possibly unknown paths
and causing electric shock and fire hazards.
3. If ventilation is poor, use an approved air-supplied
respirator.
4. Read the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instruction for metals,
consumables, coatings, and cleaners.
9. Do not use welder to thaw frozen pipes.
10.Remove stick electrode from holder or cut off
welding wire at contact tip when not in use.
5. Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator.
Shielding gases used for welding can displace air
causing injury or death. Be sure the breathing air
is safe.
WARNING
6. Do not weld in locations near degreasing, cleaning,
or spraying operations. The heat and rays of the
arc can react with vapours to form highly toxic
and irritating gases.
FLYING SPARKS AND HOT METAL can
cause injury.
7. Do not weld on coated metals, such as galvanized,
lead, or cadmium plated steel, unless the coating
is removed from the weld area, the area is well
ventilated, and if necessary, while wearing an airsupplied respirator. The coatings and any metals
containing these elements can give off toxic fumes
if welded.
1. Wear approved face shield or safety goggles. Side
shields recommended.
Chipping and grinding cause flying metal.
As welds cool, they can throw off slag.
2. Wear proper body protection to protect skin.
WARNING
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under
high pressure. If damaged, a cylinder can
explode. Since gas cylinders are normally
part of the welding process, be sure to
treat them carefully.
WARNING
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding
arc. The flying sparks and hot metal, weld
spatter, hot workpiece, and hot equipment
can cause fires and burns. Accidental contact of electrode or welding wire to metal
objects can cause sparks, overheating,
or fire.
1. Protect compressed gas cylinders from excessive
heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position
by chaining them to a stationary support or equipment cylinder rack to prevent falling or tipping.
1. Protect yourself and others from flying sparks and
hot metal.
3. Keep cylinders away from any welding or other
electrical circuits.
2. Do not weld where flying sparks can strike flammable material.
4. Never allow a welding electrode to touch any
cylinder.
Manual 0-5280 1-3
GENERAL INFORMATION
TRANSARC 170i
5. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the
specific application; maintain them and associated
parts in good condition.
6. Turn face away from valve outlet when opening
cylinder valve.
7. Keep protective cap in place over valve except
when cylinder is in use or connected for use.
8. Read and follow instructions on compressed
gas cylinders, associated equipment, and CGA
publication P-1 listed in Safety Standards.
WARNING
MOVING PARTS can cause injury.
a very large volume of scientific findings based on
experiments at the cellular level and from studies
with animals and people which clearly establish that
low frequency magnetic fields and interact with, and
produce changes in, biological systems. While most
of this work is of very high quality, the results are
complex. Current scientific understanding does not
yet allow us to interpret the evidence in a single coherent framework. Even more frustrating, it does not yet
allow us to draw definite conclusions about questions
of possible risk or to offer clear science-based advice
on strategies to minimize or avoid potential risks.”
To reduce magnetic fields in the workplace, use the
following procedures.
1. Keep cables close together by twisting or taping
them.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
2. Arrange cables to one side and away from the
operator.
1. Keep all doors, panels, covers, and guards closed
and securely in place.
3. Do not coil or drape cable around the body.
2. Stop engine before installing or connecting unit.
4. Keep welding power source and cables as far away
from body as practical.
3. Have only qualified people remove guards or
covers for maintenance and troubleshooting as
necessary.
ABOUT PACEMAKERS:
The above procedures are among those
also normally recommended for pacemaker wearers. Consult your doctor for
complete information.
4. To prevent accidental starting during servicing,
disconnect negative (-) battery cable from battery.
5. Keep hands, hair, loose clothing, and tools away
from moving parts.
6. Reinstall panels or guards and close doors when
servicing is finished and before starting engine.

1.06 EMF Information
Considerations About Welding And The Effects Of Low
Frequency Electric And Magnetic Fields
Welding current, as it flows through welding cables,
will cause electromagnetic fields. There has been
and still is some concern about such fields. However,
after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of
the National Research Council concluded that: “The
body of evidence, in the committee’s judgment, has
not demonstrated that exposure to power-frequency
electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence
continues to be examined. Until the final conclusions
of the research are reached, you may wish to minimize
your exposure to electromagnetic fields when welding
or cutting.
To reduce magnetic fields in the workplace, use the
following procedures:
1. Keep cables close together by twisting or taping
them, or using a cable cover.
2. Arrange cables to one side and away from the
operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away
from operator as practical.
5. Connect work clamp to workpiece as close to the
weld as possible.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult
their doctor and the device manufacturer before
performing or going near arc welding, spot welding,
gouging, plasma arc cutting, or induction heating
operations. If cleared by your doctor, then following
the above procedures is recommended.

3.01 Duty Cycle
The rated duty cycle of a Welding Power Source, is a statement of the time it may be operated at its rated welding
current output without exceeding the temperature limits of the insulation of the component parts. To explain the 10
minute duty cycle period the following example is used. Suppose a Welding Power Source is designed to operate
at a 30% duty cycle, 170 amperes at 26.8 volts. This means that it has been designed and built to provide the
rated amperage (170A) for 3.0 minutes, i.e. arc welding time, out of every 10 minute period (30% of 10 minutes
is 3.0 minutes). During the other 7.0 minutes of the 10 minute period the Welding Power Source must idle and
be allowed to cool.

NOTE 3
Motor start fuses or thermal circuit breakers are recommended for this application. Check local
requirements for your situation in this regard.
NOTE 4
Minimum Generator Recommendation at the Maximum Output Duty Cycle.
Due to large variations in performance and specifications of different brands and types of generators,
Cigweld cannot guarantee full welding output power or duty cycle on every brand or type of generator.
Some small generators incorporate low cost circuit breakers on their outputs. These circuit breakers
usually will have a small reset button, and will trip much faster than a switchboard type circuit breaker.
This may result in not being able to achieve full output or duty cycle from the power source / generator
combination. For this reason we recommend a generator that incorporates switchboard type circuit
breakers.
Cigweld recommends that when selecting a generator, that the particular power source / generator
combination be adequately trialled to ensure the combination performs to the users expectations.
NOTE 5
CIGWELD reserves the right to change product performance and specifications without notice.
3.03Environment
These units are designed for use in environments with increased hazard of electric shock as outlined in AS 60974.1
and AS 1674.2. Additional safety precautions may be required when using unit in an environment with increased
hazard of electric shock. Please refer to relevant local standards for further information prior to using in such areas.
A. In locations in which freedom of movement is restricted, so that the operator is forced to perform the work in
a cramped (kneeling, sitting or lying) position with physical contact with conductive parts.
B. In locations which are fully or partially limited by conductive elements, and in which there is a high risk of
unavoidable or accidental contact by the operator.
C. In wet or damp hot locations where humidity or perspiration considerably reduces the skin resistance of the
human body and the insulation properties of accessories.
Environments with increased hazard of electric shock do not include places where electrically conductive parts in
the near vicinity of the operator, which can cause increased hazard, have been insulated.
3.04Location
Be sure to locate the welder according to the following guidelines:
• In areas, free from moisture and dust.
• Ambient temperature between -10°C to 40° C (14°F to 104° F).
• In areas, free from oil, steam and corrosive gases.
• In areas, not subjected to abnormal vibration or shock.
• In areas, not exposed to direct sunlight or rain.
• Place at a distance of 300mm (12”) or more from walls or similar that could restrict natural air flow for
cooling
• The enclosure design of this power source meets the requirements of IP23S as outlined in AS60529. This
provides adequate protection against solid objects (greater than 12mm), and direct protection from vertical
drops. Under no circumstances should the unit be operated or connected in a micro environment that will
exceed the stated conditions. For further information please refer to AS 60529.

electrician.
3.05 High Frequency Introduction
3. Radiation from Welding Leads: Radiated interference
from welding leads, although pronounced in the vicinity
of the leads, diminishes rapidly with distance. Keeping
leads as short as possible will minimise this type of
interference. Looping and suspending of leads should
be avoided wherever possible.
4. Re-Radiation from Unearthed Metallic Objects: A
major factor contributing to interference is re-radiation
from unearthed metallic objects close to the welding
leads. Effective grounding of such objects will prevent
re-radiation in most cases.
3.07 Electromagnetic Compatibility
The importance of correct installation of high frequency
welding equipment cannot be overemphasized.
Interference due to high frequency initiated or stabilised
arc is almost invariably traced to improper installation.
The following information is intended as a guide for
personnel installing high frequency welding machines.
!
WARNING EXPLOSIVES
The high frequency section of this machine
has an output similar to a radio transmitter.
The machine should NOT be used in the
vicinity of blasting operations due to the
danger of premature firing
!
WARNING COMPUTER
It is also possible that operation close to
computer installations may cause computer
malfunction.
WARNING
Extra precautions for Electromagnetic
Compatibility may be required when this
Welding Power Source is used in a domestic
situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the
welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are
detected then it shall be the responsibility of the user
of the welding equipment to resolve the situation with
the technical assistance of the manufacturer. In some
cases this remedial action may be as simple as earthing
the welding circuit, see NOTE below. In other cases it
could involve constructing an electromagnetic screen
enclosing the Welding Power Source and the work,
complete with associated input filters. In all cases,
electromagnetic disturbances shall be reduced to the
point where they are no longer Trouble-some.
NOTE
3.06 High Frequency Interference
The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be
authorised by a person who is competent to
assess whether the changes will increase the
risk of injury, e.g. by allowing parallel welding
current return paths which may damage the
earth circuits of other equipment. Further
guidance is given in IEC 974-13 Arc Welding
Equipment - Installation and use (under
preparation).
Interference may be transmitted by a high frequency
initiated or stabilised arc welding machine in the
following ways.
1. Direct Radiation: Radiation from the machine can
occur if the case is metal and is not properly grounded.
It can occur through apertures such as open access
panels. The shielding of the high frequency unit in
the Power Source will prevent direct radiation if the
equipment is properly grounded.
2. Transmission via the Supply Lead: Without
adequate shielding and filtering, high frequency energy
may be fed to the wiring within the installation (mains)
by direct coupling. The energy is then transmitted by
both radiation and conduction. Adequate shielding and
filtering is provided in the Power Source.
Safety and Installation
3-4
Manual 0-5280
TRANSARC 170i
B. Assessment of Area
Before installing welding equipment, the user shall make an assessment of potential electromagnetic problems in
the surrounding area. The following shall be taken into account.
1. Other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the welding
equipment.
2. Radio and television transmitters and receivers.
3. Computer and other control equipment.
4. Safety critical equipment, e.g. guarding of industrial equipment.
5. The health of people around, e.g. the use of pace-makers and hearing aids.
6. Equipment used for calibration and measurement.
7. The time of day that welding or other activities are to be carried out.
8. The immunity of other equipment in the environment: the user shall ensure that other equipment being used
in the environment is compatible: this may require additional protection measures.
The size of the surrounding area to be considered will depend on the structure of the building and other activities
that are taking place. The surrounding area may extend beyond the boundaries of the premises.
C. Methods of Reducing Electromagnetic Emissions
1. Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations.
If interference occurs, it may be necessary to take additional precautions such as filtering of the mains supply.
Consideration should be given to shielding the supply cable of permanently installed welding equipment in
metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The shielding
should be connected to the Welding Power Source so that good electrical contact is maintained between the
conduit and the Welding Power Source enclosure.
2. Maintenance of Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations. All
access and service doors and covers should be closed and properly fastened when the welding equipment is in
operation. The welding equipment should not be modified in any way except for those changes and adjustments
covered in the manufacturer’s instructions. In particular, the spark gaps of arc striking and stabilizing devices
should be adjusted and maintained according to the manufacturer’s recommendation
3. Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at or
close to the floor level.
4. Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered. However,
metallic components bonded to the work piece will increase the risk that the operator could receive a shock by
touching the metallic components and the electrode at the same time. The operator should be insulated from
all such bonded metallic components.
5. Earthing of the Work Piece
Manual 0-5280
3-5
Safety and Installation
TRANSARC 170i
Where the work piece is not bonded to earth for electrical safety, nor connected to earth because of its size
and position, e.g. ship’s hull or building steelwork, a connection bonding the work piece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the work piece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection
of the work piece to earth should be made by direct connection to the work piece, but in some countries where
direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected according
to national regulations.
6. Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems
of interference. Screening the entire welding installation may be considered for special applications.

1. VRD ON/OFF Indicator Lights
A VRD (voltage reduction device) is a hazard reducing device designed to reduce electric shock hazards
present on the output of welding power source when operating in MMAW (stick) mode. Note that the
presence of VRD should not be used as a substitute for the use of appropriate safety practices as indicated
in section one of this manual.
Both the green and red indicator lights only operate in MMAW (stick) mode.
The green VRD ON light illuminates (red light is off) when the VRD is active. Under this condition the open
circuit voltage of the unit is limited to below 10V DC, thus reducing the potential of serious electric shock
(such as when changing electrodes).
The red VRD OFF light illuminates (green light is off) when the VRD is inactive. Under this condition the
output voltage of the unit will be at welding potential which in some cases may exceed 25V DC.
Fail to safe operation
This welding power source is also protected by a special protection feature called “Fail to Safe Operation”
which is available in this model. The output of the power source will be disabled and the fault indicator will
illuminate if the “Fail to Safe” protection has operated. The “Fail to Safe” protection will not automatically
reset. The mains power switch must be turned off to reset the power source.
The display will also show error code E-1 if the “Fail to Safe” protection has operated.

2. Digital Meter (Amps and Volts)
The digital meter is used to display the pre-set parameter values (when not welding) and actual output
current or voltage (when welding) of the power source. A long press (>2s) on the Multi Function Control
toggles between the display of amps and volts.
If you are in "amps display" mode, when not welding, long press of more than 2 seconds on the Multi
Function Control will set the 170i to "volts display" mode, the meter will show actual output volts for 5
seconds, then revert to"amps display" and allows adjustment of parameters. During welding, the meter
will show actual welding volts when selected.
If you are in "volts display" mode, when not welding, long press of more than 2 seconds on the Multi
Function Control will set the 170i to "amps display" and allows adjustment of parameters. During welding,
the meter will show actual welding amps when selected.
At the completion of welding, the meter will hold the last recorded value for a period of approximately 10
seconds. During the hold time the display will flash to indicate the hold function is active. The meter will
hold the value until; (1) the Multi Function Control is adjusted in which case the unit will revert to preview
mode, (2) welding is recommenced, in which case actual welding amperage or voltage will be displayed,
or (3) a period of 10 seconds elapses following the completion of welding in which case the unit will
return to preview mode. The value displayed in preview mode and welding mode is steady (not flashing).
3. Multi Function Control
When not welding, the Multi Function Control is used to adjust all welding parameters, including welding
amps. A short press on the Multi Function Control will save the parameter value, then increment to the
next available parameter. The parameter LED will illuminate and the Multi Function Control will then adjust
the parameter. The parameter value is shown on the meter (figure 3-1, Item 2) and the LED's next to the
meter indicate if the parameter is Amps, Seconds, %, or Hz. Another press on the Multi Function Control
will save the parameter value, then increment to the next available parameter. During welding, adjustment
of the Multi Function Control will adjust the actual welding amps, no other parameters are adjustable
during welding.
4. Parameter LED's (Weld Activity LED's)
When welding, the weld activity graph LED's will illuminate to indicate which weld sequence step is currently
active. When not welding, the parameter LED will illuminate to show which parameter is currently being
adjusted. In MMAW (Stick) mode, the adjustable parameters are weld current, hot start current & arc
force. In GTAW (Lift Tig) mode, the adjustable parameters are initial current, up slope time, weld current,
down slope time, crater current, post flow.

In 2T mode this is the current at
the end of the down slope current
ramp. When the welding current
reaches the Crater Current value,
the welding current will cease and
the unit will enter Post Flow mode.
In 4T mode, this is the current at
the end of the down slope current
ramp. The welding current will
remain at the Crater Current value
until the torch trigger is released, at
which time the welding current will
cease and the unit will enter Post
Flow mode.
Range is 5 to 170A. Factory default
is 30A.
Post Flow
This parameter operates in TIG
mode only and is used to adjust the
post gas flow time once the arc has
extinguished. This control is used
to dramatically reduce oxidation of
the tungsten electrode.
Range is 0.0 to 30.0 seconds.
Factory default is 5.0 seconds.
5. Positive Welding Output Terminal
The positive welding terminal is used to connect the welding output of the power source to the electrode
holder lead or work lead. Positive welding current flows from the power source via this heavy duty bayonet
type terminal. It is essential, however, that the male plug is inserted and turned securely to achieve a
sound electrical connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused
in the bayonet terminal.
6. Negative Welding Output Terminal
The negative welding terminal is used to connect the welding output of the power source to the TIG
torch or work lead. Negative welding current flows to the power source via this heavy duty bayonet type
terminal. It is essential, however, that the male plug is inserted and turned securely to achieve a sound

This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode the
operator can press and release the torch trigger and the output will remain active. To deactivate the power
source, the trigger switch must again be depressed and released, thus eliminating the need for the operator
to hold the torch trigger.
Note that when operating in GTAW (TIG mode), the power source will remain activated until the selected
downslope time has elapsed.
A-11725
STICK Dead Man Switch Mode (Transarc 170i Mines Spec Model)
A special trigger mode called “Dead Man Switch” mode is available on the 170i when welding with STICK
electrodes. In this mode, there will be no output voltage at all from the Power Source until the trigger is
pressed. This provides the greatest level of safety for the operator, and is mandatory on some work sites.
While the Dead Man Switch function greatly increases operator safety, standard welding safety procedures
should still be followed.
When the trigger is pressed, the VRD voltage is activated and the user can start welding as normal. For
extra safety, if welding has not commenced within 3 seconds after the trigger is pressed, the Power Source
will turn off the VRD, and the trigger must be released & pressed again to start welding.
If the trigger is released during welding, all welding power is shut off within the time limits of normal VRD
operation.
A special STICK electrode holder is required for use with a Power Source fitted with a Trigger Switch.
This electrode holder has a trigger switch attached to it, and a control cable that connects to the remote
control socket of the Power Source. The 170i Mine Spec plant comes standard with one of these special
electrode holders fitted with an integrated trigger switch.
The Dead Man Switch function is active in both 2T and 4T STICK mode.
Welding with the Dead Man Switch is as follows:
2T MODE
1. Press the trigger on the electrode holder.
2. The Power Source will now output the VRD volts and the VRD ON led will be lit.

!
WARNING
The Power Source must be turned off and unplugged from the mains supply before the Dead Man
Switch function is changed.
!
WARNING
If 4T operation is selected when using the Dead man Switch mode, the use of and observer is
recommended.
10.Process Selection Control
The process selection control is used to select the desired welding mode. Two modes are available, GTAW
(Lift TIG) and MMAW (Stick) modes. Refer to section 3.08 for GTAW (TIG) set-up details or section 4.04
for MMAW (stick) set-up details.
Note that when the unit is powered on the mode selection control will automatically default to LIFT TIG
mode. This is necessary so as to prevent inadvertent arcing should an electrode holder be connected to
the unit and mistakenly be in contact with the work piece during power up.
11.Thermal Overload Indicator
This welding power source is protected by a self resetting thermostat. The indicator will illuminate if the
duty cycle of the power source has been exceeded. Should the thermal overload indicator illuminate the
output of the power source will be disabled. Once the power source cools down this light will go OFF and
the over temperature condition will automatically reset. Note that the mains power switch should remain
in the on position such that the fan continues to operate thus allowing the unit to cool sufficiently. Do not
switch the unit off should a thermal overload condition be present.
The display will also show error code E-- in the event of an over current or over temperature.
A-11665
12.Shielding Gas Inlet
The Shielding Gas Inlet connection is used to supply the appropriate shiielding gas to the unit. Refer to
section 3.08 for GTAW (TIG) set up details.
!
WARNING
Only Inert Shielding Gases specifically designed for welding applications should be used.
13.On / Off Switch
This switch is used to turn the unit on/off.
14.Fan on Demand
The Transarc170i is fitted with a fan on demand feature. Fan on demand automatically switches the cooling
fan off when it is not required. This has two main advantages; (1) to minimize power consumption, and
(2) to minimize the amount of contaminants such as dust that are drawn into the power source.
Note that the fan will only operate when required for cooling purposes and will automatically switch off
when not required.

3.07 Shielding Gas Regulator Operating Instructions (where supplied)
!
WARNING
This equipment is designed for use with welding grade (Inert) shielding gases only.
Shielding Gas Regulator Safety
This regulator is designed to reduce and control high pressure gas from a cylinder or pipeline to the working
pressure required for the equipment using it.
If the equipment is improperly used, hazardous conditions are created that may cause accidents. It is the
users responsibility to prevent such conditions. Before handing or using the equipment, understand and
comply at all times with the safe practices prescribed in this instruction.
SPECIFIC PROCEDURES for the use of regulators are listed below.
1. NEVER subject the regulator to inlet pressure greater than its rated inlet pressure.
2. NEVER pressurize a regulator that has loose or damaged parts or is in a questionable condition. NEVER
loosen a connection or attempt to remove any part of a regulator until the gas pressure has been
relieved. Under pressure, gas can dangerously propel a loose part.
3. DO NOT remove the regulator from a cylinder without first closing the cylinder valve and releasing gas
in the regulator high and low pressure chambers.
4. DO NOT use the regulator as a control valve. When downstream equipment is not in use for extended
periods of time, shut off the gas at the cylinder valve and release the gas from the equipment.
5. OPEN the cylinder valve SLOWLY. Close after use.
User Responsibilities
This equipment will perform safely and reliable only when installed, operated and maintained, and repaired in
accordance with the instructions provided. Equipment must be checked periodically and repaired, replaced,
or reset as necessary for continued safe and reliable performance. Defective equipment should not be used.
Parts that are broken, missing, obviously worn, distorted, or contaminated should be replaced immediately.
The user of this equipment will generally have the sole responsibility for any malfunction, which results from
improper use, faulty maintenance, or by repair by anyone other than an accredited repairer.
CAUTION
Match regulator to cylinder. NEVER CONNECT a regulator designed for a particular gas or gases to
a cylinder containing any other gas.
Art: A-05087
Figure 4-5: Fit Regulator to Cylinder
Manual 0-5280 3-11
INSTALLATION, OPERATION AND SETUP
TRANSARC 170i
Installation
1. Remove cylinder valve plastic dust seal. Clean the cylinder valve outlet of impurities that may clog
orifices and damage seats before connecting the regulator.
Crack the valve (open then close) momentarily, pointing the outlet away from people and sources of
ignition. Wipe with a clean lint free cloth.
2. Match regulator to cylinder. Before connecting, check that the regulator label and cylinder marking
agree and that the regulator inlet and cylinder outlet match. NEVER CONNECT a regulator designed
for a particular gas or gases to a cylinder containing any other gas.
3. Connect the regulator inlet connection to cylinder or pipeline and tighten it firmly but not excessively,
with a suitable spanner.
4. Connect and tighten the outlet hose firmly and attach down-stream equipment.
5. To protect sensitive down-stream equipment a separate safety device may be necessary if the regulator
is not fitted with a pressure relief device.
Operation
With the regulator connected to cylinder or pipeline, and the adjustment screw/knob fully disengaged, pressurize
as follows:
1. Stand to one side of regulator and slowly open the cylinder valve. If opened quickly, a sudden pressure
surge may damage internal regulator parts.
2. With valves on downstream equipment closed, adjust regulator to approximate working pressure. It is
recommended that testing for leaks at the regulator connection points be carried out using a suitable
leak detection solution or soapy water.
3. Purge air or other unwanted welding grade shielding gas from equipment connected to the regulator
by individually opening then closing the equipment control valves. Complete purging may take up to
ten seconds or more, depending upon the length and size of the hose being purged.
Adjusting Flow Rate
Art: A-05088_AB
Figure 4-6: Adjust Flow Rate
With the regulator ready for operation, adjust working flow rate as follows:
1. Slowly turn adjusting screw/knob in (clockwise) direction until the outlet gauge indicates the required
flow rate.
NOTE
It may be necessary to re-check the shielding gas regulator flow rate following the first weld
sequence due to back pressure present within shielding gas hose assembly.
2. To reduce flow rate, allow the welding grade shielding gas to discharge from regulator by opening the
downstream valve. Bleed welding grade shielding gas into a well ventilated area and away from any
ignition source. Turn adjusting screw counterclockwise, until the required flow rate is indicated on the
gauge. Close downstream valve.

Description
The CIGWELD Foot Control is a foot operated switch and potentiometer which starts and stops the welding
process and controls welding current through operation of the foot pedal. Refer to list below for compatible
Cigweld power sources.
Installation
Attach the 8-pin connector on the end of the cable to the 8-pin receptacle on the front of the welding machine.
To complete the connection, align the keyway, insert the plug, and rotate the threaded collar fully clockwise.
Foot Control Operation
Press the foot pedal to start the machine output functions. The foot control potentiometer controls the welding
current up to the level set on the welding power source. Note that the maximum current must be set on the
power source by the operator prior to the foot control being connected, although this can be adjusted while
you are welding.
With the foot control connected, the power source will only display minimum preview Amps until the foot
control is depressed then it displays actual welding current when welding. Pressing the pedal to increases
the welding current; letting up on the pedal decreases the welding current. Releasing the pedal completely
extinguishes the arc and initiates the post-flow shielding gas timer (where fitted).
Note that some power sources may require the remote/local switch set to remote, the maximum setting of the
power source will be determined by the respective front panel control, irrespective of the remote control device
setting. As an example, if the output current on the power source front panel is set to 50% of the available
current and the remote control device is set to 100% output or maximum, the maximum achievable output
from the unit will be 50%. Should 100% output be required, the respective front panel control must be set
to 100% or maximum, in which case the remote device will then be able to control between 1-100% output.
Note: The foot control will only work correctly when power source trigger mode 2T (Normal) is selected.

THEORY OF OPERATION
5.01 Inverter Design
What does the word inverter mean?
The term inverter refers to the ability to change DC power into AC. Inverter power supplies immediately rectify the
incoming AC to DC, and then the transistors create a higher frequency AC. The higher frequency AC then goes on
to a much smaller main transformer than in a conventional power supply. The AC is then rectified to extremely
smooth DC. The diagram to the below shows the basic electrical wiring of a DC output inverter power supply.

6.13 Main Circuit Description
!
WARNING
Turn off power and disconnect mains supply plug from receptacle before working on the unit. Allow
two minutes for capacitors to discharge after disconnection from mains supply voltage.
A-11868
The mains supply voltage is connected via a double pole switch to the input rectifiers on the main inverter board
through an inbuilt EMC filter on the inverter power board. Overvoltage protection is provided by varistor CY1.
The rectifier output charges the main capacitor bank (C17, C19, C22, C23, C24 and C25) to high voltage through
PFC IGBT’s V8 and PFC diodes V7. Inrush current limiting is provided by an off board resistor R2 which is then
bypassed by relay J1 after a few seconds.
The primary igbt transistors (Q1, and Q2) switch the transformer primary at high frequency and varying duty cycle.
The transformer return wire is taken from the terminal centre of the main DC bus capacitor bank (the voltage at
this point is approximately half the DC bus voltage).
Secondary output voltage from the transformer is rectified by the output diodes (T14, to T18) to DC. This DC is
controlled by the PWM of the primary side igbt transistors, and is filtered by an inductor before connecting to the
welding output terminals.
A thermal overload device (thermal switch) is fixed to the rectifier heatsinks. When an over temperature occurs,
the control circuit inhibits the trigger, gas solenoid, and the welding output. The thermal overload indicator LED
on the front panel is illuminated.
The current transformer CT1 provides a signal to the control circuit to indicate both transformer primary current,
and also detect transformer saturation. The Hall effect current sensor CT2 is powered from regulated + & - 15VDC
supplies and provides a voltage signal proportional to the output welding current to allow the control circuit to
regulate welding current.
