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 the minimum allowable current to
a maximum of 100A.
The output current set by Output Current Knob is
shown for 3 second whenever the knob is moved.
After the 3 second the value shows is the current
select by the Remote command.
Remote Pedal: For a correct use, the “Menu GTAW”
and “Menu SYS” 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.
VRD LED (enabled on Australian Machines only):
This machine is provided by VRD (Voltage Reduction
Device) function: this reduces the voltage at the output
leads.
The VRD function is enabled by factory default only on
machines that meet the AS 1674.2 Australian Standards.
(C-Tick logo " " on/near the Rating Plate applied on the
machine).
The VRD LED is ON when the Output Voltage is below
12V with the Machine at idle (no welding time).
For others machines (CE & USA) this function is abled
into Menu SYS.
Polarity:
This icon is designated to set the polarity of the process in
use: DC+, AC stick, DC- & AC TIG operations.
NOTE: Pressing the button assigned to process
POLARITY will toggle the illumination of the icon between
DC & AC polarity.
Process:
The function of this icon is to allow the user to set the
determined process.
1. High-Frequency
TIG
2. Lift-Start TIG
3. Stick – Soft Mode (7018 style electrodes)
4. Stick- Crisp Mode (6010 Style electrodes)
NOTE : Arc control parameters, Hot start and arc force
parameters, are different in two stick modes. In menu
SMAW is possible to change hot start and arc force
diagram.
NOTE : Pressing the button assigned to PROCESS
selection will toggle the illumination of the icon from left-to-
right following the progression of the numbers.
