Controls and Operational Features
Machine Start-Up:
When the machine is turned ON an auto-test is
executed: during this test all the LEDs turn ON for a
moment; at the same time the displays shown “333” and
then “888”. During the start-up the fan is activated for a
short time, then it will restart with welding operations.
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 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.
Remote LED:
This indicator will turn on when a Remote command is
connected to the machine via the remote control
connector.
If a Remote command is connected to the Machine, the
Output Current knob operates in two different modes:
STICK and TIG:
STICK mode:
with a Remote command connected
the output of the machine is ON. A Remote Amptrol
or Pedal are allowed (trigger is ignored).
Connecting the Remote command excludes the Output
Current Knob of the Machine’s user interface. Through
the Remote command is available the full Output Current
Range.
TIG mode:
in Local and remote mode the output of
the machine is OFF. A Trigger is necessary to
enable the output.
The Output Current range selectable from the Remote
command depends by the Machine’s user interface
Output Current Knob. Eg.: if the Output Current is set to
100A with the Machine’s user interface Output Current
Knob, the Remote command will adjust the Output
Current from a minimum of 5A to a maximum of 100A.
Remote Pedal: For a correct use, the “option 30” must
be enabled in the setup menu:
2-step sequence is automatically selected
Upslope / Downslope ramps and Restart are
disabled.
Spot, Bi-Level and 4-step functions aren’t selectable
(Normal operation is restored when the Remote
command is disconnected.)
Thermal LED:
This indicator will turn on when the machine is
overheated and the output has been disabled. This
normally occurs when the duty cycle of the machine has
been exceeded. Leave the machine on to allow the
internal components to cool. When the indicator turns
off, normal operation is again possible.
Mode Pushbutton:
This pushbutton changes the welding modes of the
machine:
Stick
(SMAW)
Lift TIG
(GTAW)
HF TIG
(GTAW)
Spot
TIG
(GTAW)
The Spot TIG feature is selectable only if the “option 10”
is previously enabled in the Setup Menu. See “Setup
menu” section for options enabling / disabling.
Each welding mode is is detailed in the Operating
instruction section.
