FITTING THE CONSUMABLE WIRE
The quality of the consumable wire greatly affects how reliably a
G.M.A.W.
machine will operate. Dirty, rusty or kinked wire will not feed smoothly through the gun
cable and will cause erratic welding. Deposits from the wire will clog the gun cable liner
requiring it to be replaced prematurely.
Place the spool of welding wire onto the spool holder. The location pin should mate
with a hole provided on the wire spool body. Fit the spool retaining
'R'
clip supplied.
Check the adjustment of the spool brake, which should be set to prevent over-run
of the wire spool at the end of a weld, without unduly loading the wirefeed motor. The
braking can be adjusted by the Nyloc nut using a
15/16"
AF
or 24mm socket wrench.
FEEDING THE CONSUMABLE WIRE
Open the four roll drive mechanism by pushing the knurled thumbscrews till they
disengage with the top roller carriers, allowing the upper rollers to be rotated away from
the driven rollers. The end of the welding wire can now be passed through the wire
guides, over the bottom rollers, and into the brass gun cable adaptor end.
Check that the drive roller groove is correct for the wire in use. Refer to section
7
for drive roll and wire guide part numbers.
Return the top rollers
to
their closed position and, with the machine turned on,
press
INCH
to feed wire through the gun cable. Adjust the compression screws to
provide sufficient clamping of the drive rolls drive to achieve constant wirefeed. Do not
over tighten.

NORMAL WELDING SEQUENCE
WELD START
Closing the welding gun switch initiates this sequence of events:
The gas valve is energised and gas flow commences;
The power source contactor function
is
initiated. Welding voltage is applied
The wire drive motor and the pushlpull motor are energised, wirefeed commences
between the work piece and the consumable wire.
and the arc is established.
WELD END
Releasing the gun switch initiates this sequence of events:
The wire drive motor and the push/pull motor are de-energised, and are
After a short pre-set period, known as the 'burn-back' time, the power source
dynamically braked
to
a
stop;
contactor function is released. This period ensures that the consumable wire does
not 'freeze'
in
the weld pool. To adjust the 'burn-back' time, refer to circuit board
W34-10 in Section
6
of this manual.
The gas valve is de-energised and the flow of shielding gas ceases.
5.
GENERAL MAINTENANCE
DUST
Care should be taken
to
prevent excessive build-up of dust and dirt within the
wirefeeder. It is recommended that at regular intervals, according
to
the prevailing
conditions, the machine covers be removed and any accumulated dust be removed by
the use of dry,
low
pressure compressed air, or a vacuum cleaner.
WIREFEED
In order to obtain the most satisfactory welding results from the G.M.A. welding
process, the wirefeed must be smooth and constant.
It
is therefore important
to
observe
the following points;
Keep the gun cable liner clear of dust and swarf build-up. When replacement
becomes necessary, fit only the correct liner to suit the gun cable model. The
build-up of dust
in
a cable liner can be minimised by regular purging
of
the liner
with dry compressed air. This may be conveniently done each time the wire spool
is replaced.
Replace the welding tip as it becomes worn.
Keep the wire drive mechanism clean. Periodically check the drive rollers for
Check that the consumable wire spool holder rotates smoothly and that the

braking action is not excessive. This also may be conveniently done each time the
wire is replenished.

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. WTlA Technical Note TN7-98 also 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.
Recommended

BURN PROTECTION.
The welding arc is intense and visibly bright. Its radiation can damage eyes, penetrate lightweight
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 cuffiess 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,

WIREFEEDER MANUAL
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 perchlorethylene 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
percholorethylene.
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.
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
IO
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.1674-1974, the S.A.A. Cutting and Welding Safety Code. 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.1674-1974. 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 machine is
correctly connected and earthed.
If
unsure have machine 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.
