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 2A 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.
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 this function is disabled (the LED is
always OFF).
