Welding

IMPORTANT: Before welding, check that the data on the
power source plate correspond to the supply voltage and fre-
quency.
• Start the welder by pressing the luminous switch (pos. 1, fig.
C).
• The green LED (pos. 2, fig. C) lights up to show that the wel-
der is working and ready to use.
• Turn the welding voltage switch (pos. 9, fig. C) to the most
suitable position for the work to perform.
• Remove the gas-guide and wire-guide nozzles, allowing the
wire to flow freely during loading. Remember that the con-
tact tip must correspond to the wire diameter.
• Set the wire speed potentiometer on position 3 (pos. 3, fig.
C).

• Push the torch push button or the motor check push button
until the wire end comes out from the torch.
• Tighten the contact tip on the torch.
• Attach the correct gas-guide nozzle.
• Protect the gas-guide nozzle and the wire-guide nozzle of
the torch from sprays of solder.
• Connect the clamp of the ground lead to the piece to be wel-
ded (see fig. F).
• The welding machine is ready for welding.
• To begin welding, approach the point to be welded and
press the button on the torch.
• When you have finished welding, remove the waste, turn off
the machine and close the gas cylinder.
CONTINUOUS WELDING
Select the most suitable wire tension adjustment and speed,
using the respective controls, in function of the type of work to
be carried out. Press the torch button to start the welding cur-
rent and advancement of the wire and perform welding. After
completely the weld, release the torch button to stop the wire
advancement motor immediately. The generator is powered for
a few seconds, long enough to burn the excess wire emerging
from the torch. The gas solenoid remains open to provide for
maintaining an inert atmosphere around the welding zone. This
function is called "burn-back" and is adjustable. The control
circuit is powered, ready for the next welding cycle.
SPOT WELDING
This type of welding is recommended for repairs in automobile
body shops.
• Replace the gas-guide nozzle with
the special type for spot welding
(see fig. G)
• Set the spot welding time with the
potentiometer (pos. 5, fig. C)
• Select the most suitable tension
and speed adjustment, using the respective controls, in fun-
ction of the type of work to do.
• Press the gas-guide nozzle perpendicular to the part to be
welded.
• Press the torch button to start the welding current and
advancement of the wire.
• At the end of the set spot welding time, the wire stops
advancing automatically.
• Pressing the torch button again begins a new welding cycle.
