4. Be alert that welding sparks and hot materials from welding can easily go through small cracks and open­ings to adjacent areas.
WARNING
FUMES AND GASES can be hazardous to your health.
Welding produces fumes and gases. Breath
­ing these fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breathe 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.
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.
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.
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 air-supplied 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. 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.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 10M of the welding arc. If this is not possible, tightly cover them with approved covers.
Manual 0-5231 1-3 GENERAL INFORMATION
4. Never allow a welding electrode to touch any cylinder.
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.
TRANSMIG VAF4
!
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.
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.
NOTE
Considerations About Welding And The Effects of Low Frequency Electric and Mag
-
netic Fields
The following is a quotation from the General Con­clusions Section of the U.S. Congress, Office of Technology Assessment, Biological Effects of Power Frequency Electric & Magnetic Fields - Background Pa­per, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Office, May 1989): “...there is now 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.
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. 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.
ABOUT PACEMAKERS:
The above procedures are among those also normally recommended for pacemaker wearers. Consult your doctor for complete information.

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 IEC
60974.5.
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 considerably 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.

3.02 Location

Be sure to locate the wirefeeder 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. The enclosure design of this Wire Feeder meets the
requirements of IP23S as outlined in AS 60529. 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.
G. Precautions must be taken against the Wire Feeder
toppling over. The Wire Feeder must be located on a suitable horizontal surface in the upright position when in use.

3.03 Ventilation

WARNING
Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively ventilated.

3.04 Mains Supply Voltage Requirements

CAUTION
This wirefeeder cannot be connected directly to the mains supply. It must be connected to a suitable wirefeeder control socket on a power source.

3.05 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.
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 60974-13 Arc Weld­ing Equipment - Installation and use (under preparation).
Manual 0-5231 3-1 INSTALLATION, OPERATION AND SETUP
TRANSMIG VAF4
B. Assessment of Area
3. Welding Cables
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.
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
The welding cables should be kept as short as
possible and should be positioned close together but never coiled and 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/grounding 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.
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.
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.

The wire reel hub incorporates a 3-lobe screw which is adjusted during manufacture for optimum braking.
If it is considered necessary, adjustment can be made by turning the 3-lobe Screw inside the open end of the hub clockwise to tighten the brake. Correct adjustment will result in the wire reel circumference continuing no further than 10-20mm after release of the trigger. The electrode wire should be slack without becoming dislodged from wire spool. Please refer to Figure 3-31.

3.17 Inserting Wire into Feed Mechanism

WARNING
ELECTRIC SHOCK CAN KILL! Make certain the input power is disconnected from the power source before proceeding. Do not reattach the input power until told to do so in these instructions.
WARNING
MOVING PARTS can cause injury.
1. Swing the Pressure Adjusting Knobs down and the two Pressure Roll Arms automatically spring up.
2. Make sure the end of the wire is free of any burrs and is straight. Pass the end of wire through the Input Wire Guide and over the Feed Rolls. Make certain the proper groove is being used.
3. Pass the MIG wire over the feed roll groove and out past the MIG Torch Adaptor. Then fit the welding torch as per Subsection 3.10 ensuring the MIG wire passes into the MIG Torch liner of the MIG Torch.
4. Lower the Pressure Roll Arms.
5. Swing the Pressure Adjusting Knobs back into place.
6. Use the Pressure Adjusting Knobs to create a “snug” condition. (Clockwise to tighten and Counter Clockwise to loosen).
7. Turn ON the power supply. Set proper WFS and remove the tip from the welding torch. Depress INCH button until the wire reaches the top of welding torch. Tighten the tip again and finish inserting wire.

3.18 Feed Roll Pressure Adjustment

The roll on the swing arm applies pressure to the grooved roll via an adjustable tension device. The pressure adjusting knobs should be set to a minimum pressure that will provide satisfactory wire feed without slippage. If slipping occurs, and inspection of the wire out of the MIG Gun reveals no deformation or wear, the conduit liner should be checked for kinks or clogging from metal flakes. If this is not the cause of slipping, the Feed Roll pres­sure can be increased by rotating the pressure adjusting knobs clockwise. The use of excessive pressure may cause rapid wear of the Feed Roll, motor shaft and motor bearings.

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

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 igni-
tion. 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 3-35 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.
Shutdown
Close cylinder valve whenever the regulator is not in use. To shut down for extended periods (more than 30 minutes).
1. Close cylinder or upstream valve tightly.

1. Make sure all necessary connections have been made (Refer to Subsection 3.01 of this manual).
2. Turn ON the power source and the wire feeder.
3. All the displays and discrete LED's start self-examination and all the lights on the panel are on for 1 sec­ond. Left display shows firmware information of display PCB "DF X.X" and right display shows hardware information of display PCB "DH X.X". 1.5 seconds later left display shows firmware information of motor control PCB "PF X.X" and hardware information of motor control PCB "PH X.X".
4. Push the PURGE switch of the feeder and adjust the flow of shield gas.
5. Push the INCH switch of the feeder and adjust the WFS to the desired value by means of WFS control.
WARNING
If the gun switch is depressed, the electrode (welding wire) is electrically “hot”. Do not permit it to touch any metal or a welding arc may be established which may be injurious to someone’s eyes (flash) or skin (burn).
6. Adjust the voltage of the power source to the desired value. The gun switch must be triggered to close power source contactor.
WARNING
In wire welding, the welding wire, wire reel (if used), input guide, feed rolls, output guide, feedhead, and welding gun metal parts are all ELECTRICALLY “HOT”.

3.24 Arc Signal Override (SIL_1 #2)

WARNING
There are dangerous voltage and power levels inside this product. Turn OFF wirefeeder and disconnect from the power source before removing cover from wirefeeder.
This switch on the motor control PCB configures the wire feeder for the presence of Arc Established signals from a power source. If the power source has an Arc Established, then this switch should be OFF. If the power source does not have these ‘Arc Signals’, then this switch should be ON. This switch allows the 2T / 4T and timer features to work, although they will not be timed from the true start of the arc, but instead from when the gun trigger is pulled.
TRANSMIG 350i, 450i, 500i and 550i have the arc established signal and current feedback signal and SIL_1#2 should be set to OFF. Note that the DIP switch SIL1-#2 is factory default set to OFF.
TRANSMIG 400i, MPM20/500, MPM12/400, MPM8/270 and MPM8/255 do not have these signals, and SIL-1 #2 will need to be set to ON.

3.29 PTC Protection of Power Source Contactor Control Output

The Power Source Contactor control circuit on the TRANSMIG VAF4 provides a relay closure to the power source through pins A and B of the 19 pin control cable. This allows the welding wire to become electrically ‘HOT’ when the gun switch trigger on the welding gun is pulled. If this relay closure is NOT provided for any reason, the welding wire WILL NOT be electrically ‘HOT’. The wire will feed, but there will be NO arc when the wire touches the work.
The Transmig VAF4 has a thermal, self reset protection device in the A-B contactor circuit to protect the circuitry against a fault or overload condition. This protection device will only allow a maximum steady state current in the range of 180 to 450 milliamps (dependent on ambient temperature) to flow through pins A and B of the 19 pin control cable to the A-B contactor circuit on the Transmig VAF4.
If this acceptable current range is exceeded for any reason, the self-reset protection circuit located on the motor control PCB will be activated effectively disabling the A-B contactor circuit. Once the fault or overload condition has been corrected and the current has returned to an acceptable level, the protection device will automatically reset and normal operation can resume.
NOTE
The protection circuit will remain activated (there will be NO arc when the wire touches the work) as long as the acceptable current range is exceeded.

3.30 Ground Fault Operation

The Transmig VAF4 has been equipped with a ground fault protection circuit. This protection circuit is activated whenever excessive current flow in the protective earth ground is detected. If the ground fault protection circuit is activated, the yellow FAULT indicator on the front of the feeder will flash at a rate of approximately 0.5 second on, 0.5 second off. When a ground fault occurs, the feeder will immediately shut down the feeder, gas valve, and power source contactor. Once the ground fault protection circuit has been set, the wire feeder will not respond to a gun switch closure until the power is reset by turning the feeder off and back on.
NOTE
Before resetting power to the wire feeder after a ground fault occurrence, determine what caused the ground fault and correct the problem before attempting to weld again.

3.31 Electronic Motor Protection

The Transmig VAF4 utilizes an electronic protection circuit to protect the motor against overcurrent caused by ex­cessive load on the motor. This protection will normally trip if the motor stays in current limit for about 10 seconds and during this 10 second period the fault light will flash at a rate of approximately 0.3 second on, 0.3 second off. Once this 10 second timing period completes, the protection circuit will trip which will cause the FAULT indicator LED to light continuously, error code ERR 03 or ERR 04 (refer to Subsection 4.05 Error Code and Remedies) will be displayed and the wirefeeder will shutdown. In order to reset this condition, the power to the wirefeeder must be turned OFF then ON to reset and clear Error Code from display.
NOTE
Should this condition occur, check the wire feeding path, and make sure that there is not any restric­tions or binding on the wire, and that the feedrolls aren’t locked by some obstruction.

4.06 MIG (GMAW/FCAW) Basic Welding Technique

Two different welding processes are covered in this section (GMAW and FCAW), with the intention of pro­viding the very basic concepts in using the Mig mode of welding, where a MIG Torch is hand held, and the electrode (welding wire) is fed into a weld puddle, and the arc is shielded by an inert welding grade shielding gas or inert welding grade shielding gas mixture.
GAS METAL ARC WELDING (GMAW): This process, also known as MIG welding, CO2 welding, Micro Wire Welding, short arc welding, dip transfer welding, wire welding etc., is an electric arc welding process which fuses together the parts to be welded by heating them with an arc between a solid continuous, consumable electrode and the work. Shielding is obtained from an externally supplied welding grade shielding gas or weld­ing grade shielding gas mixture. The process is normally applied semi automatically; however the process may be operated automatically and can be machine operated. The process can be used to weld thin and fairly thick steels, and some non-ferrous metals in all positions.

The MIG Torch should be held at an angle to the weld joint. (See Secondary Adjustment Variables below)
Hold the MIG Torch so that the welding seam is viewed at all times. Always wear the welding helmet with proper filter lenses and use the proper safety equipment.
FLUX CORED ARC WELDING (FCAW): This is an electric arc welding process which fuses together the parts to be welded by heating them with an arc between a continu­ous flux filled electrode wire and the work. Shielding is obtained through decomposition of the flux within the tubular wire. Additional shielding may or may not be obtained from an externally supplied gas or gas mixture. The process is normally applied semi automatically; however the process may be applied automatically or
Do NOT pull the MIG Torch back when the arc is established. This will create excessive wire extension (stick-out) and make a very poor weld.
The electrode wire is not energized until the MIG Torch trigger switch is depressed. The wire may therefore be placed on the seam or joint prior to lowering the helmet.
CAUTION
by machine. It is commonly used to weld large diameter electrodes in the flat and horizontal position and small electrode diameters in all positions. The process is used to a lesser degree for welding stainless steel and for overlay work.

Distance from the MIG Torch Nozzle to the Work
Piece
The electrode wire stick out from the MIG Torch nozzle should be between 10mm to 20mm. This distance may vary depending on the type of joint that is being welded.
Travel Speed
The speed at which the molten pool travels influences the width of the weld and penetration of the welding run.
MIG Welding (GMAW) Variables
Most of the welding done by all processes is on carbon steel. The items below describe the welding variables in short-arc welding of 0.6mm to 6.4mm) mild sheet or plate. The applied techniques and end results in the GMAW process are controlled by these variables.
Preselected Variables

Establishing the Arc and Making Weld Beads
Before attempting to weld on a finished piece of work, it is recommended that practice welds be made on a sample metal of the same material as that of the fin­ished piece.
The easiest welding procedure for the beginner to experiment with MIG welding is the flat position. The equipment is capable of flat, vertical and overhead positions.
3. Nozzle Angle. This refers to the position of the MIG Torch in relation to the joint. The transverse angle is usually one half the included angle be­tween plates forming the joint. The longitudinal angle is the angle between the centre line of the MIG Torch and a line perpendicular to the axis of the weld. The longitudinal angle is generally called the Nozzle Angle and can be either trail­ing (pulling) or leading (pushing). Whether the operator is left handed or right handed has to be considered to realize the effects of each angle in relation to the direction of travel.

For practicing MIG welding, secure some pieces of
1.5mm or 2.0mm mild steel plate 150 x 150mm. Use
0.8mm flux cored gasless wire or a solid wire with shielding gas.
Setting of the Power Source
Power source and Wirefeeder setting requires some practice by the operator, as the welding plant has two control settings that have to balance. These are the Wirespeed control and the welding Voltage Control. The welding current is determined by the Wirespeed control, the current will increase with increased Wirespeed, resulting in a shorter arc. Less wire speed will reduce the current and lengthen the arc. Increasing the welding voltage hardly alters the current level, but lengthens the arc. By decreasing the voltage, a shorter arc is obtained with a little change in current level.
When changing to a different electrode wire diameter, different control settings are required. A thinner elec­trode wire needs more Wirespeed to achieve the same current level.
A satisfactory weld cannot be obtained if the Wirespeed and Voltage settings are not adjusted to suit the elec­trode wire diameter and the dimensions of the work piece.
Figure 4-9 Transverse and Longitudinal Nozzle Axes
If the Wirespeed is too high for the welding voltage, “stubbing” will occur as the wire dips into the molten pool and does not melt. Welding in these conditions

normally produces a poor weld due to lack of fusion. If, however, the welding voltage is too high, large drops will form on the end of the wire, causing spatter. The correct setting of voltage and Wirespeed can be seen in the shape of the weld deposit and heard by a smooth regular arc sound. Refer to the Weld Guide located on

4.07 MIG (GMAW/FCAW) Welding Troubleshooting

Solving Problems Beyond the Welding Terminals
The general approach to fix Gas Metal Arc Welding (GMAW) problems is to start at the wire spool then work through to the MIG Torch. There are two main areas where problems occur with GMAW; Porosity and Inconsistent wire feed.
Problem 1 - Porosity
When there is a gas problem the result is usually porosity within the weld metal. Porosity always stems from some contaminant within the molten weld pool which is in the process of escaping during solidification of the molten metal. Contaminants range from no gas around the welding arc to dirt on the work piece surface. Porosity can be reduced by checking the following points.
