supply and a gas hose which are to be connected to the rear
of the wire feeder.
• The power cable must be fixed to the quick-fit connector
(Pos. 1, Fig. E).
• The auxiliary cable must be fixed to the special connector
(Pos. 2, Fig. E).
• The gas tube must be connected to the quickfit connector
(Pos. 3, Fig. E).

Welding

IMPORTANT: Before welding, check that the data on the power
source plate correspond to the supply voltage and frequency.
• Start up the welder by turning the main switch (circuit break-
er) / scaled change over switch (Pos. 5, Fig. C) to position 1.
• The welder is working and ready to be used when the green
pilot light lights up (Pos. 3, Fig. C).
• Set the change over switch for finely regulating weld volt-
age (Pos. 7, Fig. C) to the best position for the job on hand.
• 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.
• Regulate the wire speed potentiometer located on the front
panel of the wire feeder to position 3.
• 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 weld-
ed (see Fig. G).
• 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 cir-
cuit is powered, ready for the next welding cycle.
