Burn Protection
The welding arc is intense and visibly bright. Its radiation can damage eyes,
penetrate light-weight clothing, reflect from lightcoloured surfaces, and burn
the skin and eyes. Burns resulting from gas-shielded arcs resemble acute
sunburn, but can be more severe and painful.
Wear protective clothing – leather or heat resistant gloves, hat, and safety-
toe boots. Button shirt collar and pocket flaps, and wear cuff less trousers
to avoid entry of sparks and slag.
Avoid oily or greasy clothing. A spark may ignite them. Hot metal such as
electrode stubs and work pieces should never be handled without gloves.
Ear plugs should be worn when welding in overhead positions or in a confined
space. A hard hat should be worn when others are working overhead.
Flammable hair preparations should not be used by persons intending to weld or
cut.
Toxic Fumes
Adequate ventilation with air is essential. Severe discomfort, illness or
death can result from fumes, vapours, heat, or oxygen depletion that welding
or cutting may produce. NEVER ventilate with oxygen.
Lead, cadmium, zinc, mercury, and beryllium bearing and similar materials when
welded or cut may produce harmful concentrations of toxic fumes. Adequate
local exhaust ventilation must be used, or each person in the area as well as
the operator must wear an air-supplied respirator. For beryllium, both must be
used.
Metals coated with or containing materials that emit fumes should not be
heated unless coating is removed from the work surface, the area is well
ventilated, or the operator wears an air-supplied respirator.
Work in a confined space only while it is being ventilated and, if necessary,
while wearing air-supplied respirator.
Vapours from chlorinated solvents can be decomposed by the heat of the arc (or
flame) to form phosgene, a highly toxic gas, and lung and eye irritating
products. The ultra-violet (radiant) energy of the arc can also decompose
trichlorethylene and perchloroethylene vapours to form phosgene. Do not weld
or cut where solvent vapours can be drawn into the welding or cutting
atmosphere or where the radiant energy can penetrate to atmospheres containing
even minute amounts of trichlorethylene or perchloroethylene.
Fire and Explosion Prevention
Be aware that flying sparks or falling slag can pass through cracks, along
pipes, through windows or doors, and through wall or floor openings, out of
sight of the operator. Sparks and slag can travel up to 10 metres from the
arc.
Keep equipment clean and operable, free of oil, grease, and (in electrical
parts) of metallic particles that can cause short circuits.
If combustibles are present in the work area, do NOT weld or cut. Move the
work if practicable, to an area free of combustibles. Avoid paint spray rooms,
dip tanks, storage areas, ventilators. If the work can not be moved, move
combustibles at least 10 metres away out of reach of sparks and heat; or
protect against ignition with suitable and snug-fitting fire-resistant covers
or shields.
5
Weldmatic 356 & 396 | Operator Manual | Model No CP147-2, CP148-2
Walls touching combustibles on opposite sides should not be welded on or cut.
Walls, ceilings, and floor near work should be protected by heat-resistant
covers or shields.
A person acting as Fire Watcher must be standing by with suitable fire
extinguishing equipment during and for some time after welding or cutting if;
Combustibles (including building construction) are within 10 metres.
Combustibles are further than 10 metres but can be ignited by sparks.
Openings (concealed or visible) in floors or walls within 10 metres may
expose combustibles to sparks.
Combustibles adjacent to walls, ceilings, roofs, or metal partitions can be
ignited by radiant or conducted heat.
After work is done, check that area is free of sparks, glowing embers, and
flames.
A tank or drum which has contained combustibles can produce flammable vapours
when heated. Such a container must never be welded on or cut, unless it has
first been cleaned as described in AS.1674-2. This includes a thorough steam
or caustic cleaning (or a solvent or water washing, depending on the
combustible’s solubility), followed by purging and inerting with nitrogen or
carbon dioxide, and using protective equipment as recommended in AS.1674-2.
Water-filling just below working level may substitute for inerting.
Hollow castings or containers must be vented before welding or cutting. They
can explode. Never weld or cut where the air may contain flammable dust, gas,
or liquid vapours.
Shock Prevention
Exposed conductors or other bare metal in the welding circuit, or ungrounded
electrically alive equipment can fatally shock a person whose body becomes a
conductor. Ensure that the equipment is correctly connected and earthed. If
unsure have the equipment installed by a qualified electrician. On mobile or
portable equipment, regularly inspect condition of trailing power leads and
connecting plugs. Repair or replace damaged leads.
Fully insulated electrode holders should be used. Do not use holders with
protruding screws. Fully insulated lock-type connectors should be used to join
welding cable lengths.
Terminals and other exposed parts of electrical units should have insulated
knobs or covers secured before operation.
If the supply cable is damaged it must be replaced by the manufacturer, their
service agent or a similarly qualified person.

1 INTRODUCTION
Gas Metal Arc Welding (G.M.A.W.) is an arc welding process where a consumable
wire is fed by motor driven feed rolls to a welding gun, and where welding
current is supplied from the welding power source. The welding arc is struck
between the work piece and the end of the wire, which melts into the weld
pool. The arc and the weld pool are both shielded by gas flow from the gun, or
in the case of “self shielded” wires, by gases generated by the wire core.
The process is very versatile in that by selection of the correct wire
composition, diameter and shielding gas, it can be used for applications
ranging from sheet-metal to heavy plate, and metals ranging from carbon steel
to aluminium alloys.
The Weldmatic Fabricator has been designed to be used with consumable wires in
the range from 0.6mm to 1.6mm diameter. The smaller wire sizes are used when
welding at lower currents, such as sheet-metal applications. Increasing the
wire diameter permits higher welding currents to be selected.
A common application of G.M.A.W. is for welding Mild Steel. In this
application, a Mild Steel solid consumable wire such as AUSTMIG ES6 is used
with a shielding gas of Carbon Dioxide, or Argon mixed with Carbon Dioxide.
Alternatively, Flux-cored consumable wires are available in both gas shielded,
and `gasless’ self shielding types.
Stainless steel and Aluminium can be welded with G.M.A.W. using the correct
consumable wire and shielding gas.

5 INSTALLATION
Connection to Electrical Mains Power Supply
NOTE. All electrical work shall only be undertaken by a qualified electrician.
The Weldmatic 356 is supplied with a 5 metre 4 core 47/0.20 Heavy Duty PVC
mains power supply cable. The Weldmatic 396 is supplied with a 5 metre 4 core
50/0.25 Heavy Duty PVC mains power supply cable. This cable should be
correctly connected to a suitable 3 Phase plug top or fixed connection point.
The minimum capacity of the mains wiring and power outlet supplying a welder
is selected according to the effective primary current of the machine. The
effective primary current for Weldmatic 356 and Weldmatic 396 are 15 Amps.
The minimum recommended mains circuit breaker rating for a Weldmatic 356 is 20
Amps and Weldmatic 396 is 25 Amps.
Note: Due to normal variations of sensitivity, the tripping time of some
circuit breakers may limit the duty cycle available from the Weldmatic 356 &
396 machines. A higher rated circuit breaker can be selected, but the mains
wiring capacity must be increased to suit.
The current rating of the mains cable depends on cable size and method of
installation. Refer to AS/NZS 3008.1, Table 9.
If it becomes necessary to replace the mains flexible supply cable, use only
cable with correct current rating. Access to the supply terminals is gained by
removing the power source side panels. The replacement cable must be fitted
and retained in the same manner as the original.

6 NORMAL WELDING SEQUENCE
Weld Start Closing the welding gun switch initiates this sequence of events:
The gas valve is energised and gas flow
commences and continues for any pregas time set The power source contactor
function is initiated. Welding voltage is applied between the work piece and
the consumable wire The wire drive motor is energised The wire touches the
work piece, and the arc is established. Weld End Releasing the gun switch
initiates this sequence of events: The wire drive motor is de-energised, and
is dynamically braked to a stop After a short pre-set period, known as the
burn-back’ time, the Power-source contactor function is released. This period ensures that the consumable wire does notfreeze’ in the weld pool At the
completion of any post-gas time set, the gas valve is de-energised and the
flow of shielding gas ceases.
12
7 BASIC WELDING INFORMATION
Choice of Shielding Gas
The choice of shielding gas is largely determined by the consumable wire to be used. Many proprietary shielding gas mixtures are available.
The recommended shielding gases for use with the Weldmatic 356 & 396 are:
Mild Steel: Aluminium:
Argon + 5 to 25% Carbon Dioxide; 100% CO
2
Argon;
Stainless Steel: Argon + 1 to 2% Oxygen.
Consult your gas supplier if more specific information is required.
Shielding Gas Flow Rate
In G.M.A. welding, one function of the shielding gas is to protect the molten
weld pool from the effects of oxygen in the atmosphere. Without this
protection the weld deposit becomes `honeycombed’ in appearance, an effect
which is described as weld porosity.
In draft-free conditions the gas flow rate required to give adequate
protection is typically 10-12 litres/min. In situations where drafts cannot be
avoided, it may be necessary to increase this rate up to 20 litres/min, and/or
to provide screening of the work area.
Weld porosity can also be caused by air entering the gas stream through a
damaged hose, loose gas connection, or from restriction in the nozzle, such as
from excess build-up of spatter.
When welding aluminium, particular care must be taken with all aspects of
shielding gas delivery and workpiece preparation in order to avoid weld
porosity.
Establishing a Weld Setting
Once the consumable wire type, wire size and shielding gas have been chosen,
the two variables that are adjusted in order to obtain a the desired weld
setting are;
Wirefeed speed,
Welding arc voltage.
The wirefeed speed determines the welding current; increasing the speed
increases the current, and decreasing it decreases current.
The selected wirefeed speed must be matched with sufficient arc voltage; a
speed increase requires an increase of arc voltage.
If the voltage is too low the wire will stub and stutter, and there will not
be a steady arc. If the voltage is too high the arc will be long with metal
transfer occurring as a series of large droplets.
Important: Do not operate the Voltage Control switches during welding.
The weld setting should be chosen to suit the application and the thickness of
the metal to be welded. It is important to check that the deposited weld
provides sufficient strength to suit the application.
A “good” weld will have the characteristics illustrated in Figure 4. The weld
has penetrated into the parent metal, fusing the root of the joint where the
two plates meet, and the weld blends smoothly into the side walls.
A “bad” weld is shown in Figure 5. The weld has not penetrated the joint root,
and there is poor side wall fusion. This lack of fusion would normally be
corrected by increasing the arc voltage, or by increasing both wirefeed speed
and arc voltage to achieve a higher current weld setting.

Gun Position
For “down hand” fillet welding, the gun is normally positioned as shown in
Figure 6 below with the nozzle end pointing in the direction of travel.
8 GENERAL MAINTENANCE
Before removing the power source covers, ENSURE that the equipment is
disconnected from the mains power supply. When the equipment is energised
LETHAL VOLTAGES are present on the electrical components enclosed.
Fig 6 Gun Position
Dust
Care should be taken to prevent excessive build-up of dust and dirt within the
welding power source. It is recommended that at regular intervals, according
to the prevailing conditions, the equipment covers be removed and any
accumulated dust be removed by the use of a dry, low pressure compressed air,
or a vacuum cleaner. The machine should be blown out with compressed air at
least every 12 months as grinding dust can settle on PCB componentry causing
failure. Failure to maintain machines may void warranty.
Wirefeed
In order to obtain the most satisfactory welding results from the G.M.A.W.
process, the wirefeed must be smooth and constant. Most causes of erratic
wirefeed can be cured by basic maintenance. Check the General Maintenance
section of the Wirefeeder Operators Manual for more details.
