Connect a suitable plug (2p+e) of proper capacity to the
mains cable and fix to a socket fitted with fuses or auto-
matic switch: the proper earth terminal must be connected
to the earth connector (yellow-green) of the main supply.

Gas connection

The units are supplied with a pressure
reducer complete with pressure gauge for
adjustment of the pressure of the gas used
in welding. The gas cylinders (optional)
must be placed on the rear cylinder-sup-
port platform of the welding machine and
secured with the chain supplied. They
must be installed in a way that does not
interfere with the stability of the welding
machine. The connections between the
gas tank, reducer and gas pipe, from the
back panel of the welder, to be made as
shown in fig. B. Open the gas cyclinder
and regulate the flowmeter to about 8/12
l/min.
ATTENTION: Check that the gas used is
compatible with the material to be welded.

Instructions for use

COMMAND AND CONTROL UNITS (fig. C)
Pos. 1 On/off switch.
Pos. 2 Green LED. This LED lights up when the welder is
powered and ready to work.
Pos. 3 Potentiometer for adjustment of wire speed.
Pos. 4 Welding process switch. It can be set to the following
positions:
• 2 strokes. In position
pressed down throughout the entire welding procedure.
• 4 strokes. In position
then release the torch key to start welding; press again to
stop.
Pos. 5 Potentiometer with switch for regulating the spot wel-
ding time.
Pos. 6 Potentiometer for adjusting BURN-BACK.
Pos. 7 Potentiometer for adjusting motor startup (RAMP). If
motor speed is set to maximum, do not select the
ramp under position 2. A motor brush protection
device prevents this from happening.
Pos. 8 Yellow thermostat protection LED. This LED lights up
when the overheating protection trips. You are
working beyond the work cycle (see "Limits of use").
Wait a few minutes before continuing the welding.
Pos. 9 Multi-position switch for fine adjustment of welding
voltage.
Pos. 10 Centralized torch connection.
Pos. 11 Snap-in connector for ground line.

Connection of torch and ground
wire
• Connect the rear end of the welding torch to the centralized
connector on the front panel (pos. 10, fig. D).
• Insert the ground wire in the snap connector (pos. 11, fig. D).

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 rear guide (pos. 1, fig. E)
on the drive mechanism.
• Raise the idle roller (pos. 7 fig. E) to release the roller pres-
sure device (pos. 5, fig. E). Check that the diameter of the
wire used is punched on the outer face of the drive roller
(pos. 3, fig. E).
• Thread a few centimetres of wire into the wire guide of the
centralised connector (pos. 4, fig. E). Lower the idle roller
arm making sure the wire enters the drive roller cavity. If
necessary, adjust the pressure between the rollers by turning
the relative screw (pos. 5, fig. E). The correct value is the
minimum pressure preventing the rollers from slipping on the
wire. Excessive pressure can deform the wire and cause it to
get tangled at the sheath entrance while insufficient pressure
leads to irregular welding.
