Connection for TIG welding
- Connect (5) the earth clamp to the positive socket (+) (6)
ofthe power source.
- Connect the TIG torch coupling (7) to the torch socket (-) (8)
ofthe power source.
- Connect the gas hose from the cylinder to the rear gas con-
nection.
- Connect the signal cable (9) of the torch to the appropriate
connector (10).
- Connect the gas hose (11) of the torch to the appropriate
union/connection (12).

3 SYSTEM PRESENTATION

3.1 General

These constant current inverter power sources are able to per-
form the following types of welding with excellent results:
- MMA
- TIG with remote arc striking by high frequency (TIG
HF-START) and control of the gas supply by the torch button
- TIG with contact ignition with reduction of short circuit cur-
rent (TIG LIFT-START) and control of gas delivery by means of
torch button (selectable from set-up).
In inverter welders, the output current is unaffected by va-
riations in the supply voltage and the length of the arc, and is
perfectly levelled, giving the best welding quality.

3.2 Front control panel

1 Power supply
Indicates that the equipment is connected to the mains
and is on.
2 General alarm
Indicates the possible intervention of protection devices
such as the temperature protection (consult the "Alarm
codes" section).
3 Power on
Indicates the presence of voltage on the equipment
outlet connections.
4 Welding methods
Allows the functions and the parameters management
in both manual and robot welding.
Manual welding
Robot welding
5 Welding process
Allows the selection of the welding procedure.
Electrode welding (MMA)
2 STEP TIG welding
In 2 Step, pressing the button causes the gas to flow and
strikes the arc; when the button is released the current
returns to zero in the slope descent time; once the arc
is extinguished, the gas flows for the post-gas time.
