1. If the electrode points to the welding piece it provokes the
short-circuit between the piece and the electrode.
2. Pressing the torch key the pre gas is set. The end of the
pre gas is indicated by a long BEEP. If that operation is car-
ried out starting from the post gas you get the long BEEP im-
mediately as soon as you press the torch key.
3. During the BEEP it is possible to lift the electrode from the
piece provoking the arc fuse.
4. Two Times Welding.
Active only in TIG mode.
By pressing the function key 8 - Picture 1 Page 4.) you can posi-
tion the luminous indicator on symbol 5 - Picture 1 Page 4.) . In
this mode you press the torch button to prime the welding current
and it should be pressed whilst welding.
5. Four Times Welding.
Active only in TIG mode.
By pressing the function key 8 - Picture 1 Page 4.) you can posi-
tion the luminous indicator on symbol 6 - Picture 1 Page 4.) . In
this mode the torch button works in four times for an automatic
weld. The gas flux is activated by first pressing the torch button.
By releasing the button the welding arc is primed. The second
pressing on the torch button interrupts the welding. By releasing
the gas flux is deactivated.
6. Spot Welding.
Active only in TIG mode.
can position the luminous indicator on symbol 7 - Picture 1 Page
4.) . In this mode you obtain a spot welding timed with a set up tim-
er as described on reference 24 - Spot time.
7. TIG pressed.
Once the TIG mode is selected (Lift or HF), press the function key
11 - Picture 1 Page 4.) until the luminous indicator reaches the
position on symbol 9 - Picture 1 Page 4.) . In this mode the current
pulsates between a maximum and a minimum value and can be
set up as described on reference 22: Nominal Current Welding
and e 23: Reduced Current respectively.
8. TIG DC.
Once the TIG (Lift or HF) mode is selected press the function key
11 - Picture 1 Page 4.) until the luminous indicator reaches the
position on symbol 10 - Picture 1 Page 4.) .
9. Remote.
In order to connect the remote control press the function key 14 -
Picture 1 Page 4.) until the luminous indicator reaches the posi-
tion on symbol 12 - Picture 1 Page 4.) .
10. Local.
In order to connect the remote control press the function key 14 -
Picture 1 Page 4.) until the luminous indicator reaches the posi-
tion on symbol 13 - Picture 1 Page 4.) .

Press the function keys 31 o 32 - Picture 1 Page 4.) for at least a
second with the symbols
In order to select the welding parameters that you wish to modify.
By pressing a function key you select the different welding modes.
Please note that during every single parameter the corresponding
luminous indicator lights up. The display 17 - Picture 1 Page 4.)
and the led 18 - Picture 1 Page 4.) indicate the parameter's value
and unity measure respectively.

MEANING
Insufficient voltage entry, line switch open or lack of line,
no V regulated.
Interface connector disconnected, absence of the 24V
auxiliary voltage, other interface problems..
Power converter overheated.
Restoration occurs when the alarm stops.
Short-circuit caused by:
a) Generator's terminal output in short-circuit.
b) Output stage failure.
a) Eliminate the short-circuit.
b) Call after-sales service.
The inverter stage does not work properly.
