voltage reducer. Use equipment with DC output.
14. Wear a safety harness to prevent falling if working
above floor level.
15. Keep all panels and covers securely in place.
Manual 0-5143 1-1 GENERAL INFORMATION
TRANSMIG 175i
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.

GENERAL INFORMATION 1-2 Manual 0-5143
WARNING
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.
1. Keep your head out of the fumes. Do not breath
the fumes.
2. If inside, ventilate the area and/or use exhaust at
the arc to remove welding fumes and gases.
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.
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.
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.
TRANSMIG 175i
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.
4. Be alert that welding sparks and hot materials from
welding can easily go through small cracks and
openings to adjacent areas.
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.
7. Do not weld on closed containers such as tanks
or drums.
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.
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.
WARNING
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal.
As welds cool, they can throw off slag.
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.
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 yourself and others from flying sparks and
hot metal.
1. Wear approved face shield or safety goggles. Side
shields recommended.
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.
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.
3. Keep cylinders away from any welding or other
electrical circuits.
2. Do not weld where flying sparks can strike flammable material.
Manual 0-5143 1-3 GENERAL INFORMATION
4. Never allow a welding electrode to touch any
cylinder.
TRANSMIG 175i
!
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.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards closed
and securely in place.
2. Stop engine before installing or connecting unit.
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.
2. Arrange cables to one side and away from the
operator.
3. Do not coil or drape cable around the body.
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.
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.
WARNING
This product, when used for welding or
cutting, produces fumes or gases which
contain chemicals know to the State of
California to cause birth defects and, in
some cases, cancer. (California Health &
Safety code Sec. 25249.5 et seq.)

2.09 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 15% duty cycle, 90 amperes at 23.6 volts. This means that it has been designed and
built to provide the rated amperage (90A) for 1.5 minutes, i.e. arc welding time, out of every 10 minute period
(15% of 10 minutes is 1.5 minutes). During the other 8.5 minutes of the 10 minute period the Welding Power
Source must idle and be allowed to cool.

NOTE
Note 1: The Effective Input Current should be used for the determination of cable size & supply
requirements.
Note 2: Motor start fuses or thermal circuit breakers are recommended for this application.
Check local requirements for your situation in this regard.
Note 3: Minimum Generator Recommendation at the Maximum Output Duty Cycle.
Due to large variations in performance and specifications of different brands and types of genera
tors, 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 break
ers 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.
In some circumstances, long welds at high welding current may trip the circuit breaker on the
generator.
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.

SECTION 3:
INSTALLATION, OPERATION AND SETUP
3.01 Environment
These units are designed for use in environments
with increased hazard of electric shock as outlined in
AS 60974.1 and AS 1674.2. Note the Transmig 175i
Plant Part No. W1005175M (Asia Version) is not
fitted with VRD. 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. Examples of environments with increased hazard
of electric shock are:
1. 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.
2. 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.
3. In wet or damp hot locations where humidity
or perspiration considerable reduces the
skin resistance of the human body and the
insulation properties of accessories.
B. 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.
G. 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.
H. Precautions must be taken against the power
source toppling over. The power source must
be located on a suitable horizontal surface in the
upright position when in use.
3.03 Ventilation
Since the inhalation of welding fumes can be harmful,
ensure that the welding area is effectively ventilated.
3.04 Mains Supply Voltage Requirements
The Mains supply voltage should be within ± 15%
of the rated mains supply voltage. Too low a voltage
may cause poor welding performance. Too high a
supply voltage will cause components to overheat
and possibly fail.
The Welding Power Source must be:
• Correctlyinstalled,ifnecessary,byaqualied
electrician.
• Correctlyearthed (electrically)in accordance
with local regulations.
3.02 Location
Be sure to locate the welder according to the following
guidelines:
A. In areas, free from moisture and dust.
B. Ambient temperature between 0° C to 40° C.
C. In areas, free from oil, steam and corrosive
gases.
D. In areas, not subjected to abnormal vibration or
shock.
E. In areas, not exposed to direct sunlight or rain.
F. Place at a distance of 300mm or more from walls
or similar that could restrict natural air flow for
cooling.

a qualified Electrical Tradesperson.
3.05 Electromagnetic Compatibility
WARNING
Extra precautions for Electromagnetic
Compatibility may be required when
this Welding Power Source is used in a
domestic situation.
TRANSMIG 175i
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 troublesome.
NOTE
The welding circuit may or may nor 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 60974-13 Arc Welding Equipment Installation and use (under preparation).
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, signalling
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
pacemakers and hearing aids.
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 it’s 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
stabilising devices should be adjusted and
maintained according to the manufacturer’s
recommendations.
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.
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
INSTALLATION, OPERATION AND SETUP 3-2 Manual 0-5143
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
TRANSMIG 175i
the electrode at the same time. The operator should be insulated from all such bonded metallic
components.
5. Earthing of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of it’s
size and position, e.g. ship’s hull or building steelwork, a connection bonding the workpiece to earth
may reduce emissions in some, but not all instances. Care should be taken to prevent the earthing of
the workpiece increasing the risk of injury to users, or damage to other electrical equipment. Where
necessary, the connection of the workpiece to earth should be made by direct connection to the
workpiece, 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. Power Indicator
The power indicator is illuminated when the correct mains power is applied to the power source and when
the ON/OFF switch located on the rear panel is in the ON position.
2. VRD ON/OFF Indicator Lights (South Pacific Version Only)
WARNING
VRD is NOT fitted to Transmig 175i (Asia Version) Plant Part No W1005175M.
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 35V 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 35V DC.
3. Digital Amps Meter
The digital amperage meter is used to display both the pre-set current (Stick and TIG modes only) and
actual output current (all modes) of the power source.
At times of non-welding, the amperage meter will display a pre-set (preview) value in both MMAW (Stick)
and GTAW (TIG) modes. This value can be adjusted by varying the amperage potentiometer (item 4). Note
that in GMAW/FCAW (MIG) mode, the amperage meter will not preview welding current and will display
zero.
When welding, the amperage meter will display actual welding current in all modes.
At the completion of welding, the amperage meter will hold the last recorded amperage value for a period
of approximately 10 seconds in all modes. The amperage meter will hold the value until; (1) any of the front
panel controls are adjusted in which case the unit will revert to preview mode, (2) welding is recommenced,
in which case actual welding amperage 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.
4. Amperage Control (Wirespeed)
The amperage control knob adjusts the amount of welding current delivered by the power source. In
MMAW (stick) and GTAW (TIG) modes, the amperage control knob directly adjusts the power inverter to
deliver the desired level of output current. In GMAW/FCAW modes (MIG), the amperage knob adjusts the
speed of the wire feed motor (which in turn adjusts the output current by varying the amount of MIG wire
delivered to the welding arc). The optimum wire speed required will dependent on the type of welding
application. The setup chart on the inside of the wire feed compartment door provides a brief summary
of the required output settings for a basic range of MIG welding applications.
5. MIG Torch Adaptor (Euro Style)
The MIG torch adaptor is the connection point for the MIG welding torch. Connect the torch by pushing
the torch connector into the brass torch adaptor firmly and screwing the plastic torch nut clockwise to
secure in position. To remove the MIG Torch simply reverse these directions.
INSTALLATION, OPERATION AND SETUP 3-4 Manual 0-5143
TRANSMIG 175i
6. Positive Welding Output Terminal
The positive welding terminal is used to connect the welding output of the power source to the appropriate
welding accessory such as the MIG torch (via the MIG torch polarity lead), 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.
7. MIG Torch Polarity Lead
The polarity lead is used to connect the MIG torch to the appropriate positive or negative output terminal
(allowing polarity reversal for different welding applications). In general, the polarity lead should be
connected in to the positive welding terminal (+) when using steel, stainless steel or aluminium electrode
wire. When using gasless wire, the polarity lead is generally connected to the negative welding terminal (-).
If in doubt, consult the manufacturer of the electrode wire for the correct polarity. 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.
8. Negative Welding Output Terminal
The negative welding terminal is used to connect the welding output of the power source to the appropriate
welding accessory such as the MIG torch (via the MIG torch polarity lead), 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 electrical connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused
in the bayonet terminal.

10. Multifunction Control - Voltage, Down Slope & Arc Force
The multifunction control knob is used to adjust three main parameters depending on the welding mode
selected.
When GMAW/FCAW (MIG) Mode is Selected
In this mode the control knob is used to adjust the output voltage of the unit. The welding voltage is
increased by turning the knob clockwise or decreased by turning the knob anti-clockwise. The optimum
voltage level required will dependent on the type of welding application. The setup chart on the inside
of the wire feed compartment door provides a brief summary of the required output settings for a basic
range of MIG welding applications.
When MMAW (Stick) Mode is Selected
In this mode the multifunction control knob is used to adjust arc force. Arc force control provides an
adjustable amount of welding force (or “dig”) control. This feature can be particularly beneficial in
providing the operator the ability to compensate for variability in joint fit-up in certain situations with
particular electrodes. In general increasing the arc force control toward ‘10’ (maximum arc force) allows
greater penetration control to be achieved. Arc force is increased by turning the control knob clockwise
or decreased by turning the knob anti-clockwise
