Loading wire

• Open the moving part of the cover and fit the coil (Ø 300
mm) onto the support in such a way that the wire unwinds in
a clockwise direction and centres the projecting reference of
the support with the matching hole in the coil.
• Thread the end of the wire into the back guide (Pos. 1, Fig. F)
on the drawing mechanism.
• Raise the idle roller (Pos. 7, Fig. F) to release the roller pres-
sure device (Pos. 5, Fig. F). Check that the diameter of the
wire used is punched on the outer face of the drive roller
(Pos. 3, Fig. F).
• Thread the wire into the wire guide of the centralized attach-
ment (Pos. 4, Fig. F) for a few centimetres. Lower the idle
roll-holder arm making sure the wire goes into the slot of the
drive roll. If necessary, adjust the pressure between the roll-
ers with the screw provided (Pos. 5, Fig. F). The correct pres-
sure is the minimum that does not allow the rollers to skid
on the wire. Excessive pressure will case deformation of the
wire and tangling on the entrance of the sheath; insufficient
pressure can cause irregular welding.

Assembly of drive rollers

5
Unscrew the ring nut (Pos. 6, Fig. F). Lift up the arms holding
the idle roller (Pos. 2, Fig. F) and proceed as follows:
• Each roller shows the type of wire and diameter on the two
6
external sides.
• Install the right rolls (Pos. 3, Fig. F) making sure the groove is
in the correct position for the diameter of the wire being used.
• Screw up the ring nut again (Pos. 6, Fig. F).

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 scaled change over switch
(Pos. 1, Fig. D) to position 1.
• The green LED (Pos. 2, Fig. D) lights up to show that the
welder is working and ready to use.
• Turn the welding voltage switch (Pos. 9, Fig. D) 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. D).
• 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.
