• computers or controlling and measuring instrument;
• safety and protection devices.
The welder must not be rested on a slant of more than 10°.
These welding machines are cooled through air forced-circula-
tion. That is why they must be disposed to facilitate the suction
and the emission of air through the slots of the frame.
The welding unit is characterized by the following classes:
• IP 23 protection class indicates that the generator can be
used in both interior and exterior environments.
• The "S" usage class indicates that the generator can be
employed in environments with a high risk of electrical
shocks.

Connection to the electrical supply

Connection of the machine to the user line (electrical cur-
rent) must be performed by qualified personnel.
All connections must be made in conformity with existing regu-
lations while fully respecting the accident-prevention laws (see
CEI 26-10 CENELEC HD 427 regulations).
Before connecting the cutting equipment to the mains sup-
ply, check that the data on the machine plate correspond
to the supply voltage and frequency and its main switch
is on the "O" position.
These welders can work at different voltages and are normally
supplied to work at the highest voltage shown on the data plate.
Check that this voltage corresponds to the mains supply. If not,
remove the cover and connect up the corresponding red or blue
wire, according to the mains voltage, as indicated in Fig. B.
Connection to the mains supply must be carried out using a
four-core wire supplied with the welder, of which:
• three wires must be connected to the mains supply.
• the fourth one, YELLOW-GREEN, to EARTH.
Connect a suitable plug (3p+t) to the primary cable and
fix to a socket fitted with fuses or automatic switch; the
proper earth terminal must be connected to the earth con-
nector (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 (optional). The gas cylinders must be placed on
the rear cylinder-support 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. C.
Open the gas cyclinder and regulate the flowmeter to about
8/12 l/min.
WARNING: Check that the gas used is compatible with the
material to be welded.

Instructions for use

COMMAND AND CONTROL UNITS (Fig. D-E)
Pos. 1 Rack panel (See fig. F).
Pos. 2 Snap-in connector for ground line. These welders
offer the possibility of selecting two inductance val-
ues so as to modify the welding bath by altering the
dynamic characteristics of the generator. The selec-
tion is made in function of the welding current (pass
from position
rent).
Pos. 3 Opening to wire up the cooling system.
RACK PANEL (Fig. F)
Pos. 1 Multi-position switch for fine adjustment of welding
voltage.
Pos. 2 Welding process switch. It can be set to the following
positions:
• 2 strokes - In position
kept pressed down throughout the entire welding
procedure.
• 4 strokes - In position
and then release the torch key to start welding;
press again to stop.
Pos. 3 Green LED. This LED lights up when the welder is
powered and ready to work.
Pos. 4 Potentiometer with switch for regulating the spot weld-
ing time.
Pos. 5 Potentiometer for adjusting "Burn back".
Pos. 6 Centralized torch connection.
Pos. 7 Housing for connecting up the rapid couplings to cool
the MIG/MAG welding torch.
Pos. 8 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. 9 Potentiometer for adjustment of wire speed.
Pos. 10 Yellow thermostat protection LED. This LED lights up
when the overheating protection trips. You are work-
ing beyond the work cycle (see "Limits of use"). Wait
a few minutes before continuing the welding.
Pos. 11 Welding voltage selection switch.

Connection of torch and ground wire

• Connect the rear end of the welding torch to the centralized
connector on the front panel (Pos. 6, Fig. F).
• Insert the ground wire in the snap connectors(Pos. 2,
Fig. D).

Loading wire

• Insert the spool (300 mm MAX) onto its support so that the
wire unwinds anticlockwise and centre up the protruding ref-
erence point on the support with the respective opening in
the spool.
• Thread the end of the wire into the back guide (Pos. 1, Fig.
G) on the drawing mechanism.
• Lift up the idle roll (Pos. 8, Fig. G) releasing the roll pressure
device (Pos. 5, Fig. G). Make sure that the drive rolls (Pos. 3,
Fig. G) have the diameter corresponding to the wire being
used stamped on the outside.
• Thread the wire into the central wire guide (Pos. 9, Fig. G)
and into the wire guide of the centralized attachment (Pos. 4,
Fig. G) 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 rollers with the
screw provided (Pos. 5, Fig. G). The correct pressure is the
minimum that does not allow the rollers to skid on the wire.
Excessive pressure will case deformation of the wire and tan-
gling on the entrance of the sheath; insufficient pressure can
cause irregular welding.
