TIG pressed
Once the TIG mode is selected (Lift or HF), press the
function key 11 - Picture 1 Page 6.) until the luminous
indicator reaches the position on symbol 9 - Picture 1
Page 6). 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.
TIG DC
Once the TIG (Lift or HF) mode is selected press the
function key 11 - Picture 1 Page 6.) until the luminous
indicator reaches the position on symbol 10 - Picture 1
Page 6.).
Remote
In order to connect the remote control press the function
key 14 - Picture 1 Page 6.) until the luminous indicator
reaches the position on symbol 12 - Picture 1 Page 6.).
Local
In order to connect the remote control press the function
key 14 - Picture 1 Page 6.) until the luminous indicator
reaches the position on symbol 13 - Picture 1 Page 6.).
Alarm Indicator
When one of the alarms goes off the indicator 15 -
Picture 1 Page 6.) and the display 17 - Picture 1 Page
6.) The alarm, the relative indications and the
instructions to follow to restore the generator are shown
immediately:
DISPLAY
Insufficient voltage entry, line switch open
–– –– ––
or lack of line, no V regulated.
Interface
LtF absence of the 24V auxiliary voltage,
other interface problems.
Power converter overheated.
ThA
Restoration occurs when the alarm stops.
Short-circuit caused by:
Generator's terminal output in short-
circuit.
SCA
Output stage failure.
Eliminate the short-circuit.
Call after-sales service.
PiF The inverter stage does not work properly.
whenever all the panel luminous indicators remain on or
off simultaneously for more than 40 seconds it will be
necessary to contact the manufacturer.
Current supply
The indicator 16 - Picture 1 Page 6.) lights up every time
the generator is supplying a current.

Welding process profile
In this section of the panel you can set up all the
parameters in order to improve the process previously
selected.
Function keys
Press the function keys 31 o 32 - Picture 1 Page 6.) 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 6.) and the led 18 - Picture 1 Page
6.) indicate the parameter's value and unity measure
respectively.
This section of the panel is changeable during welding.
Pre gas
By pressing function keys 31 e 32 the luminous indicator
is position at 19 - Picture 1 Page 6.); then by activating
the knob 30, the time length for the gas flux is set up in
seconds. The value range is between 0,2 and 5
seconds.

Initial Current
By pressing function keys 31 e 32 the luminous indicator
is position at 20 - Picture 1 Page 6.); then by activating
the knob 30, the value for the initial current on the mode
TIG Four Times is set up. The value range is between I
Min and the nominal current welding.
