SAFE PRACTICES WHEN USING
WELDING EQUIPMENT
These notes are provided in the interests
of improving operator safety. They should
be considered only as a basic guide to
Safe Working Habits. A full list of Standards
pertaining to industry is available from
the Standards Association of Australia,
also various State Electricity Authorities,
Departments of Labour and Industry or
Mines Department and other Local Health
or Safety Inspection Authorities may have
additional requirements. Australian Standard
AS1674.2 provides a comprehensive guide
to safe practices in welding.
Eye Protection
NEVER LOOK AT AN ARC WITHOUT
PROTECTION. Wear a helmet with safety
goggles or glasses with side shields
underneath, with appropriate filter lenses
protected by clear cover lens. This is a
MUST for welding, cutting, and chipping to
protect the eyes from radiant energy and
flying metal. Replace the cover lens when
broken, pitted, or spattered.

manual is set out to enable you
to properly maintain your new
equipment and ensure that you
obtain maximum operating efficiency.
Please ensure that this information
is kept in a safe place for ready
reference when required at any future
time.
When ordering spare parts, please
quote the model and serial number
of the power source and part
number of the item required. All
relevant numbers are shown in lists
contained in this manual. Failure to
supply this information may result in
unnecessary delays in supplying the
correct parts.
SAFETY
Before this equipment is put into
operation, please read the Safe
Practices section of this manual.
This will help to avoid possible injury
due to misuse or improper welding
applications.
PLASTIC HANDLES ON
POWER SOURCE
Please note that the handles fitted to
the Weldmatic 356 and 396 power
source are intended for carrying the
equipment by hand only.
DO NOT use these handles for
suspending or mounting the power
source in any other manner.

54
Burn Protection
The welding arc is intense and visibly bright.
Its radiation can damage eyes, penetrate
light-weight clothing, reflect from light-
coloured 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.

Weldmatic 356 & 396 | Operator Manual | Model No CP147-2, CP148-2
76
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
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. Fig 2 Positive Wire

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 pre-
gas 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 not ‘freeze’ 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.
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: Argon + 5 to 25%
Carbon Dioxide;
100% CO2
– Aluminium: 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.

1312
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.

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.
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.
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.
