INTRODUCTION
Gas Metal Arc Welding (G.M.A.W.) is basically a simple welding process, where a
consumable wire is fed by motor driven rollers
to
a welding gun and 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 shie.lded by gas flow from the gun, or in the case of ‘self shielded’ wires, by
gases generated by the wire core.
The process is quite versatile in that by selecting the correct wire composition,
diameter and shielding gas, it can be used for applications ranging from sheetmetal
to
heavy plate, and metals ranging from carbon steel
to
aluminium alloys.
The WELDMATIC W41-1 WIREFEEDER has been designed
to
feed
a
range of
hard, soft, and flux-cored wires for the Gas Metal Arc Welding process. A compact motor
with integral gear box
is
coupled
to
a four roll drive assembly forming the basic
component of the wire feeder. The motor is controlled by an electronic speed control
which ensures excellent speed regulation over the full torque range of the motor, with
inherent compensation for supply voltage variations.

GENERAL MAINTENANCE
OPERATOR
CHECKS
If the wire feeder motor will not turn when gun switch is operated and speed
control is set
to
desired speed, check the following points;
1.
Ensure that
30
Volts A.C. power
is
available at wirefeeder and Power
Indicator is
lit.
Check fuse located on power source front panel
(IO
Amp) and
check fuse located on wirefeeder printed circuit board
(5
Amp).
2.
Operate ‘INCH’ switch. If motor turns, fault may be either in gun switch or the
switch wires in the gun cable. If motor does not turn, check connections
to
motor and visually check printed circuit board ensuring that all components,
wiring and electrical connections are secure.
If wirefeeder fuses fail repeatedly while welding, check the following points;
1.
Check tension of
spool
holder or wire reel brake, Reel
or
spool should only
have sufficient pressure applied
to
prevent over run when motor
stops.
2.
Ensure feed roll pressure is only sufficient
to
push wire evenly. Excessive
pressure can deform electrode wires.
3.
Ensure wire feed liner is clean. Blow
out
or replace if necessary.
4.
Ensure tip is free of obstructions, ream out if necessary. Replace tip when
5.
Ensure wire is straight and free of buckles.
6.
Ensure wire is free of rust, replace if necessary.
7.
Ensure feed roll gear teeth are free of interfering material.

FITTING THE GUN CABLE
The BERNARD BEXT2-4E350AE gun cable is equipped with a 'Euro' wirefeeder
connector which incorporates all required connection points
to
the gun cable for welding
current, shielding gas and gun switch control.
To attach the gun cable
to
the wirefeeder mechanism, engage the mating parts of
the male and female Euro connectors, then rotate the locking ring clockwise
to
firmly
secure the connection.
FITTING THE CONSUMABLE WIRE
The quality of the consumable wire greatly affects how reliably a gas metal arc
welder will operate. For best results when welding mild steel, we recommend quality
WIA AUSTMIG ES6. 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
/
WIRE INCH
With reference to Figure 6, release the pressure screw fixing shaft
(1
g),
and rotate
the pressure arms (16)
to
the open positions. The end of the welding wire can now be
passed through the inlet guide, over the bottom driven rollers, and into the output wire
guide tube, Check that the drive roller grooves are correct for the wire in use. The
appropriate size
is
stamped on the visible side of the installed roller. Check also that the
correct size contact tip is fitted at the gun end. Drive roller and tip details are available in
Section
8
of this manual.
Return the pressure arms to the closed position and adjust the compression screw
to
provide sufficient clamping of the drive rolls
to
achieve constant wirefeed.
Do
not over
tighten.
With the machine energised, operate the INCH switch
to
feed wire through the gun
cable.

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.
WTlA
Technical Note TN7-98 also provides a comprehensive guide
to
safe
practices in welding.

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 cuffless 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 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
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.1674-1974, 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.
