1.01 Arc Welding Hazards

WARNING
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live when­ever the output is on. The input power cir­cuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats or covers.
4. Disconnect input power or stop engine before installing or servicing this equipment. Lock input power disconnect switch open, or remove line fuses so power cannot be turned on acciden­tally.
5. Properly install and ground this equipment accord­ing to its Owner’s Manual and national, state, and local codes.
6. Turn off all equipment when not in use. Disconnect power to equipment if it will be left unattended or out of service.
7. Use fully insulated electrode holders. Never dip holder in water to cool it or lay it down on the ground or the work surface. Do not touch holders connected to two welding machines at the same time or touch other people with the holder or electrode.
8. Do not use worn, damaged, undersized, or poorly spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth) ground.
11. Do not touch electrode while in contact with the work (ground) circuit.
12. Use only well-maintained equipment. Repair or replace damaged parts at once.
13. In confined spaces or damp locations, do not use a welder with AC output unless it is equipped with a 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 0-5282 1-1 GENERAL INFORMATION83
TRANSARC 130i
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.

GENERAL INFORMATION 1-2 Manual 0-5282
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.
TRANSARC 130i
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 con
­tact 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 0-5282 1-3 GENERAL INFORMATION83
4. Never allow a welding electrode to touch any cylinder.
TRANSARC 130i
!
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.)

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 25% duty cycle, 130 amperes at 25.2 volts. This means that it has been designed and built to provide the rated amperage (130A) for 2.5 minutes, i.e. arc welding time, out of every 10 minute period (25% of 10 minutes is 2.5 minutes). During the other 7.5 minutes of the 10 minute period the Welding Power Source must idle and be allowed to cool.

TRANSARC 130i
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.

3.03 Environment

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

3.05 High Frequency Introduction

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.

3.07 Electromagnetic Compatibility

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.

3.06 High Frequency Interference

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.
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.
NOTE
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).
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 pace­makers and hearing aids.
SAFETY AND INSTALLATION
3-4 Manual 0-5282
TRANSARC 130i
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
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.

Figure 4-1: Front Panel Figure 4-2: Rear Panel
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.
Manual 0-5282 4-1 INSTALLATION, OPERATION AND SETUP

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 all welding modes. 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.
A-11690
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 130i to "volts display" mode, the meter will show actual output volts for 5 seconds, then revert to display & adjustment of parameters. During welding, the meter will show actual welding volts.
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 130i to "amps display" mode, the meter will revert to display & adjustment of parameters. During welding, the meter will show actual welding amps.
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 %. 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.
