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 Welding voltage selection switch.
Pos. 11 Centralized torch connection.
Pos. 12 Snap-in connector for ground line. These welders
offer the possibility of selecting two inductance
values so as to modify the welding bath by altering
the dynamic characteristics of the generator. The
selection is made in function of the welding current
(pass from position
current).
Connection of torch and ground
wire
• Connect the rear end of the welding torch to the centralized
connector on the front panel (pos. 11, fig. E).
• Insert the ground wire in the snap connector (pos. 12, fig. E).
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. F)
on the drive 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 a few centimetres of wire into the wire guide of the
centralised connector (pos. 4, fig. F). 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. F). 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.

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 (COMPACT
270-310 pos. 1, fig. D) or turning the scale switch (COM-
PACT 360 pos. 10, fig. D) to 1.
• The green LED (pos. 2, fig. D) lights up to show that the wel-
der 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.
