A. Power Switch: It turns ON / OFF the input power to
the machine.
B. Input cable: Connect it to the mains.
C. Fan: Do not obstruct or filter the fan inlet. The
"F.A.N." (Fan As Needed) feature automatically turns
OFF/ON the fan. When the Machine is turned ON
the fan is turned ON only for the startup time (few
seconds). The fan will start with welding operations
and will continue to run whenever the Machine is
welding. If the Machine doesn't weld for more than
10minutes, it will go in Green Mode.
Green Mode
The Green Mode is a feature that puts the machine
in a stand-by condition:

The output is disabled

The fans are speed down

Only the Power ON LED remains ON.

Display show the dash char
This reduces the amount of dirt that can be drawn
inside the Machine and the power consumption.
To restore the Machine restart to weld or push the
TIG trigger or push any buttons in the front panel or
turn the encoder knob.
NOTE: If a COOLER TIG torch cooling unit is
connected to the machine, it will be turned ON/OFF
by the Green Mode feature based also on COOL
option. See Menu SYS section for more details.
Idle Mode
After 30 minutes without welding the machine will
enter a deep low power mode. It will shut down all
indicators: only Power ON Led is blinking.
To restore the Machine push the trigger or push any
buttons in the front panel or turn the encoder
Exit procedure will take 6-7s: after this time the unit
is ready to weld.

Controls and Operational Features
Machine Start-Up:
When the machine is turned ON an auto-test is
executed.
The Machine is ready to operate when on the Front
Control Panel lights up the "Power ON" LED, the "A"
LED (placed on the middle of the synoptic) with one of
the LED of the Welding "MODE" command. This is the
minimum condition: depending by the welding selection
others LEDs may be ON.
Front Panel Indicators and Controls
Power ON LED:
This LED blinks during the machine start-up or during
restart after idle mode and lights up steadily when the
machine is ready to operate.
If the Input Voltage Overrange protection becomes
active, the Power ON LED starts blinking and an error
code is shown on the displays. The machine restarts
automatically when the Input Voltage returns in the
correct range. For further detail read the Error Codes
and Troubleshooting section.
If the trigger is pushed before the unit is ready to weld,
or after a weld is completed in GTAW mode, the Power
ON LED will blink at a fast rate. Release the trigger to
restore normal operation.
