ING OPERATIONS.
1SSAFETY PPRECAUTIONS
WELDING AND ARC CUTTING CAN BE HARMFUL TO
YOURSELF AND OTHERS. The user must therefore be
educated against the hazards, summarized below, deriv-
ing from welding operations. For more detailed informa-
tion, order the manual code 3.300.758
ELECTRIC SHOCK - May be fatal.
•Install and earth the welding machine according
to the applicable regulations.
•Do not touch live electrical parts or electrodes
with bare skin, gloves or wet clothing.
•Isolate yourselves from both the earth and the work-
piece.
•Make sure your working position is safe.
FUMES AND GASES - May be hazardous to your health.
•Keep your head away from fumes.
•Work in the presence of adequate ventilation,
and use ventilators around the arc to prevent
gases from forming in the work area.
ARC RAYS - May injure the eyes and burn the skin.
•Protect your eyes with welding masks fitted with
filtered lenses, and protect your body with appro-
priate safety garments.
•Protect others by installing adequate shields or cur-
tains.
RISK OF FIRE AND BURNS
•Sparks (sprays) may cause fires and burn the
skin; you should therefore make sure there are no
flammable materials in the area, and wear appro-
priate protective garments.
NOISE This machine does not directly produce noise
exceeding 80dB. The plasma cutting/welding pro-
cedure may produce noise levels beyond said
limit; users must therefore implement all precautions
required by law.
PACEMAKERS
•The magnetic fields created by high currents may affect
the operation of pacemakers. Wearers of vital electronic
equipment (pacemakers) should consult their physician
before beginning any arc welding, cutting, gouging or
spot welding operations.

Make sure that the wire diameter corresponds to the
diameter indicated on the wire feeder roller, and that the
selected program is compatible with the material and
type of gas. Use wire feeder rollers with a "U"-shaped
groove for aluminum wires, and with a "V"-shaped groove
for other wires.
4.1.1 CConnecting tthe ggas hhose
The gas cylinder must be equipped with a pressure regu-
lator and flow gauge.
If the cylinder is placed on the cylinder shelf of the wire
feeder, it must be fastened using the chain provided.
Connect the gas hose leaving the rear of the machine to
the pressure regulator, only after positioning the cylinder.
The gas flow must be adjusted to approximately 8-10

• Press the torch trigger to move the wire forward until it
comes out of the torch.
Caution: keep your face away from the gun tube assem-
bly while the wire is coming out.
• Screw the contact tip back on, making sure that the
hole diameter is the same as that of the wire used.
• Assemble the gas nozzle.
• Open the cylinder
4.3 WWELDING CCARBON SSTEEL
In order to weld these materials you must:
• Use a welding gas with a binary composition, usually
ARGON + CO2 with percentages of Argon ranging from
75% upward. With this blend, the welding bead will be
well jointed and attractive.
Using pure CO2 as a protection gas will produce narrow
beads, with greater penetration but a considerably
increase in splatters.
• Use a welding wire of the same quality as the steel to
be welded. It is best to always use good quality wires,
avoiding welding with rusted wires that could cause
welding defects.
• Avoid welding rusted parts, or those with oil or grease
stains.
4.4 WWELDING SSTAINLESS SSTEEL
Series 300 stainless steels must be welded using a pro-
tection gas with a high Argon content, containing a small
percentage of O2 or carbon dioxide CO2 (approximately
2%) to stabilize the arc.
Do not touch the wire with your hands. It is important to
keep the welding area clean at all times, to avoid conta-
minating the joint to be welded.
4.5 WWELDING AALUMINUM
In order to weld aluminum you must use:
• Pure Argon as the protection gas.
• A welding wire with a composition suitable for the base
material to be welded.
• Use mills and brushing machines specifically designed
for aluminum, and never use them for other materials.
• For welding aluminum you must use the torch: PULL

Three currents are available, which may be called up
during welding using the torch start button.
Welding begins when the torch button is pressed. The
welding current used will be the one set using the SC
function (in this specific instance 13 =130%). This
current will be kept for as long as the torch trigger is
held down; when released, the first current changes
to the welding current, set with the knob B, within the
time established by the Slo function (in this specific
instance, 0.5 sec.), and will be kept until the torch
trigger is pressed again. The next time the torch trig-
ger is pressed, the welding current will switch to the
third or "crater-filler" current, set with the function
CrC (in this specific instance, 6 = 60%), in the time
established by the function Slo (in this specific
instance, 0.5 sec), and will be maintained as long as
the torch trigger is held down. Welding stops when
the trigger is released.
If this function is not activated, pressing the torch trigger
activates the next function.

7MMAINTENANCE
• Safety ggas nnozzle
This nozzle must be periodically cleaned to remove splat-
tered metal. Replace if distorted or squashed.
• Contact ttip.
Only a good contact between this contact tip and the wire
can ensure a stable arc and optimum current output; you
must therefore observe the following precautions:
A) The contact tip hole must be kept free of grime and
oxidation.
B) Splattered metal sticks more easily after long welding
sessions, blocking the wire flow.
The tip must therefore be cleaned more often, and
replaced if necessary.
C) The contact tip must always be firmly screwed onto
the torch body. The thermal cycles to which the torch is
subjected can cause it to loosen, thus heating the torch
body and tip and causing the wire to advance unevenly.
• Wire lliner.
This is an important part that must be checked often,
because the wire may deposit copper dust or tiny shav-
ings. Clean it periodically along with the gas lines, using
dry compressed air.
The liners are subjected to constant wear and tear, and
therefore must be replaced after a certain amount of time.
• Gearmotor ggroup.
Periodically clean the set of feeder rollers, to remove any
rust or metal residue left by the coils. You must periodi-
cally check the entire wire feeder group: hasp, wire
guide rollers, liner and contact tip.
