SECTION 1: GENERAL INFORMATION
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 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 conned 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.
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 o toxic fumes if welded.
WARNING
WELDING can cause re or explosion.
Sparks and spatter y o from the welding arc.
The ying sparks and hot metal, weld spatter, hot
workpiece, and hot equipment can cause res
and burns. Accidental contact of electrode or
welding wire to metal objects can cause sparks,
overheating, or re.
1. Protect yourself and others from ying sparks and hot
metal.
2. Do not weld where ying sparks can strike ammable
material.
3. Remove all ammables within 10M 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 re, and keep a re extinguisher nearby.
6. Be aware that welding on a ceiling, oor, bulkhead, or
partition can cause re 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 re hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut o welding
wire at contact tip when not in use.
WARNING
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause ying metal. As
welds cool, they can throw o slag.
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.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators,
hoses, and ttings designed for the specic
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
ngers 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 qualied 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 nished 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.)
NOTE
Considerations About Welding And The
Eects of Low Frequency Electric and Magnetic Fields
The following is a quotation from the General Con-
clusions Section of the U.S. Congress, Oce of Technology
Assessment, Biological Eects of Power
Frequency Electric & Magnetic Fields - Background Paper,
OTA-BP-E-63 (Washington, DC: U.S. Government Printing
Oce, May 1989): “...there is now a very large volume of
scientic ndings based on experiments at the cellular
level and from studies with animals and people which
clearly establish that low frequency magnetic elds and
interact with, and produce changes in, biological systems.
While most of this work is of very high quality, the results
are complex. Current scientic 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 denite conclusions about questions of possible
risk or to oer clear science-based advice on strategies to
minimize or avoid potential risks.”
To reduce magnetic elds 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.
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.
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 from water falling as spray at
an angle up to 60o from vertical. 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
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 Wire feeder 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.
Since the inhalation of welding fumes can be harmful,
ensure that the welding area is eectively ventilated.
3.04 Mains Supply Voltage Requirements
CAUTION
This Wire feeder cannot be connected directly to the mains supply.
It must be connected to a suitable
Wire feeder 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.
SECTION 3: installation, Operation and Setup
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 earthgrounding 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 lters. In all cases, electromagnetic disturbances shall be reduced to the point
where they are no longer troublesome.
NOTE
The welding circuit may or may
not be earthed for safety reasons.
Changing the earth-grounding ar-
rangements should only be authorised
by a person who is competent to as-
sess whether the changes will increase
the risk of injury, e.g. by allowing paral-
lel welding current return paths which
may damage the grounding circuits
of other equipment. Further guidance
is given in IEC 60974-13 Arc Welding
Equipment - Installation and use (un-
der 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, signal-
ling and telephone cables; above, below and
adjacent to the welding equipment.
2. Radio and television transmitters and receiv-
ers.
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 measure-
ment.
7. The time of day that welding or other activi-
ties 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.
20
SECTION 3: INSTALLATION, OpErATION AND SETUp
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 ltering 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 modied in any way except for those
changes and adjustments covered in the
manufacturer’s instructions.
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.
3. Welding Cables
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 oor level.
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.

There are 3 holes on the spool hub support. The top screw hole is for installing a coil of 400mm
(30kg) diameter. In this case a 30kg coil holder must be used. The 30kg coil holder is attached to the
spool hub in the same way as for a 300mm spool, then the coil is placed over the 30kg coil holder &
locked in place. The middle hole is for installing a spool of 300mm diameter (as shown in Figure 3-27).
The bottom hole is for installing a spool of 200mm diameter. As delivered from the factory, the unit
has the spool hub tted into the middle (300mm spool) position.
1. Remove the retaining clip from the spool hub.
2. Install the wire spool over the spool hub, locating the hole in the spool, with the alignment pin
on the spoolhub.
3. Insert the retaining clip back into the spool hub.
NOTE
Install the welding wire spool so that the wire feeds from the bottom of the spool into
the input wire guide.

The roll on the swing arm applies pressure to the grooved roll via an adjustable tension device.
The pressure adjusting knob 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 akes. 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.

4.05 MIG (GMAW/FCAW) Basic Welding Technique
Two dierent 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.

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 ux lled
electrode wire and the work. Shielding is obtained through decomposition of the ux 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 by machine. It is commonly used to weld large diameter electrodes in the
at 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 inuences 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
Preselected variables depend upon the type of material being welded, the thickness of the material, the welding position, the deposition rate and the mechanical properties. These variables are:
5° to 15°
Longitudinal
Angle
Art # A-08996
• Typeofelectrodewire
• Sizeofelectrodewire
• Typeofgas((notapplicableforFCAWselfshieldingwires)
• Gasowrate(notapplicableforFCAWselfshieldingwires)
Primary Adjustable Variables
These control the process after preselected variables have been found. They control the penetration, bead width, bead height, arc stability, deposition rate and weld soundness. They are:
• ArcVoltage
• Weldingcurrent(wirefeedspeed)
• Travelspeed

SECTION 4: SErvICE
Electrode Stick-Out

Secondary Adjustable Variables
These variables cause changes in primary adjustable variables which in turn cause the desired
change in the bead formation. They are:
1. Stick-out (distance between the end of the contact tube (tip) and the end of the electrode
wire). Maintain at about 10mm stick-out
2. Wire Feed Speed. Increase in wire feed speed increases weld current, Decrease in wire feed
speed decreases weld current.

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 eects of each angle in relation to the direction of travel.

Establishing the Arc and Making Weld Beads
Before attempting to weld on a nished piece of work, it is recommended that practice welds be
made on a sample metal of the same material as that of the nished piece.
The easiest welding procedure for the beginner to experiment with MIG welding is the at posi-
tion. The equipment is capable of at, vertical and overhead positions.
For practicing MIG welding, secure some pieces of 1.5mm or 2.0mm mild steel plate 150 x
150mm. Use 0.8mm ux cored gasless wire or a solid wire with shielding gas.
Setting of the Power Source
Power source and Wire feeder 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 dierent electrode wire diameter, dierent 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.
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 the inside
of the wirefeed compartment door for setup information.
Electrode Wire Size Selection
The choice of Electrode wire size and shielding gas used depends on the following
• Thickness of the metal to be welded
• Typeofjoint
• CapacityofthewirefeedunitandPowerSource
• Theamountofpenetrationrequired
• Thedepositionraterequired
• Thebeadproledesired
• Thepositionofwelding
• Costofthewire

4.06 MIG (GMAW/FCAW) Welding Troubleshooting
Solving Problems Beyond the Welding Terminals
The general approach to x 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 solidication 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.
FAU LT CAUSE
1 Shielding gas cylinder contents and
ow meter.
2 Gas leaks. Check for gas leaks between the regulator/cylinder connection and in
3 Internal gas hose in the Power Source. Ensure the hose from the solenoid valve to the MIG Torch adaptor has
4 Welding in a windy environment. Shield the weld area from the wind or increase the gas ow.
5 Welding dirty, oily, painted, oxidized
or greasy plate.

nozzle and the work piece.

working order.
Ensure that the shielding gas cylinder is not empty and the ow meter
is correctly adjusted to 15 litres per minute.

not fractured and that it is connected to the MIG Torch adaptor.
Clean contaminates o the work piece.
Keep the distance between the MIG Torch nozzle and the work piece to
a minimum.
A Ensure that the gas holes are not blocked and gas is exiting out of the
torch nozzle.
B Do NOT restrict gas ow by allowing spatter to build up inside the MIG
Torch nozzle.
C Check that the MIG Torch O-rings are not damaged.

Problem 2 - Inconsistent Wire Feed
WARNING
Disengage the feed roll when testing for gas ow by ear.
Wire feeding problems can be reduced by checking the following points.
FAU LT CAUSE
1 Feed roller driven by motor in the cabinet
slipped.
2 Wire spool unwound and tangled. Wire spool brake is too loose.
3 Worn or incorrect feed roller size A Use a feed roller matched to the size you are welding.
4 Wire rubbed against the misaligned guides
and reduced wire feed ability.
5 Liner blocked with swarf A Increased amounts of swarf are produced by the wire passing through
6 Incorrect or worn contact tip A The contact tip transfers the weld current to the electrode wire. If the
Wire spool brake is too tight.
B Replace feed roller if worn.
Misalignment of inlet/outlet guides
the feed roller when excessive pressure is applied to the pressure roller
adjuster.
B Swarf can also be produced by the wire passing through an incorrect
feed roller groove shape or size.
C Swarf is fed into the conduit liner where it accumulates thus reducing
wire feed ability.
hole in the contact tip is too large then arcing may occur inside the
contact tip resulting in the wire jamming in the contact tip
B When using soft wire such as aluminium it may become jammed in the
contact tip due to expansion of the wire when heated. A contact tip
designed for soft wires should be used.
7 Poor work lead contact to work piece If the work lead has a poor electrical contact to the work piece then the
connection point will heat up and result in a reduction of power at the
arc.
8 Bent liner This will cause friction between the wire and the liner thus reducing wire
feed ability
