8. Selection button (red LED on) for the re-
gulation of the current from the front pa-
nel or from the remote control, manual or
foot. Note: with foot remote control, gene-
rator works only in 2T mode.
With the system in H2O configuration,
keep this button pressed for 5 seconds:

the LED will start flashing and the display
(pos. 3) will show the message "H2O" for
a few seconds. Soon after, the equipment
performs an inspection to make sure the
hydraulic circuit to cool the welding torch
is functioning well. When cooling fluid
pressure/flow is not sufficient, the display
will show the message "H2O" again,

the yellow alarm LED (pos. 11) will start
flashing and the welding process will be
interrupted. To return to the air version
of the system configuration (no cooling
unit and H2O torch), keep button 8 pres-
sed for 5 seconds. The red LED that was
flashing will now remain on.
9. Selection button (red LED on) for the vi-
sualization of welding voltage or current
on the appliance. At the end of welding
only current or new values presetting is
displayed (no information on voltages va-
lues: on welding or no load).
10. Power voltage present (green LED on).
Note: blinking upon switch on and in the
case of overvoltage, unit is not working.
11. Thermal protection intervention (yellow
LED on)
Note: With the system in H2O configura-
tion, the yellow LED will start flashing to
warn of insufficient cooling fluid pressure/
flow and the welding process will be in-
terrupted.
WARNING: When the yellow LED is on,
do not cut off power from the current
generator, as this would interrupt ven-
tilation to the overheated parts. When
the yellow LED goes off, the welding
process may continue.
