Installation

Select the location of the machine to ensure satisfactory and
reliable service. Before installing the welding set the user must
take into account possible electromagnetic problems of the
working area. In particular, we suggest installing the equip-
ment away from:
• Signalling, control and telephone cables.
• Radiotelevision transmitters and receivers.
• 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 S 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 em-
ployed 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 prop-
er earth terminal must be connected to the earth connec-
tor (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 se-
cured 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 Multi-position switch for fine adjustment of welding
voltage.
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
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. 5 Potentiometer with switch for regulating the spot weld-
ing 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 de-
vice prevents this from happening.
Pos. 8 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. 9 Welding voltage selection switch.
Pos. 10 Centralized torch connection.
Pos. 11 Snap-in connector for ground line. These welders of-
fer the possibility of selecting two inductance values
so as to modify the welding bath by altering the dy-
namic characteristics of the generator. The selection
is made in function of the welding current (pass from
position to

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. E).
• Insert the ground wire in the snap connectors(Pos. 11, Fig. E).
