Front Panel Controls
Output Current Knob: Potentiometer used
to set the output current used during
welding.
Power ON/OFF LED: This LED lights up
when the machine is ON.
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's (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).
Welding Mode Switch: With three
positions, controls the welding mode of
the machine: two for Stick welding (Soft
and Crisp) and one for Lift TIG welding.

Soft Stick: For a welding with a low
spatter presence.

Crisp Stick: For an aggressive
welding, with an increased Arc
stability.

Lift TIG: When the mode switch is in
the Lift TIG position, the stick welding
functions are disabled and the
machine is ready for Lift TIG welding.
Lift TIG is a method of starting a TIG
weld by first pressing the TIG torch
electrode on the work piece in order
to create a low current short circuit.
Then, the electrode is lifted from the
work piece to start the TIG arc.
Meter: The meter displays the preset
welding current before welding and the
actual welding current during welding.

Error condition list.
If occurs, try to turn Off the machine, wait for a few
seconds, then turn ON again. If the error remains, a
maintenance is required. Please contact the nearest
technical service center or Lincoln Electric and report the
3-digit code displayed on the meter of the Front Panel.
Error code table
Slow blinking: about 1 time per second
Fast blinking: about 10 time per second
Input overvoltage
LED is blinking slow.
Indicates that an Input Voltage Overrange
9.01
protection is active; the Machine restarts
automatically when the Input Voltage returns in
the correct range.
Input undervoltage
LED is blinking fast.
Indicates that an Input Voltage Underrange
9.02
protection is active; the Machine restarts
automatically when the Input Voltage returns in
the correct range.
DC bus short circuit
Indicates that an Internal Power Circuitry fault
condition is detected.
9.03
To restore the machine:
Turn OFF then ON the Mains Switch to restart
the machine.
Boost voltage lock out
Indicates that an Internal Auxiliary Voltage fault
condition is detected.
9.04
To restore the machine:
Turn OFF then ON the Mains Switch to restart
the machine.
Inverter voltage lock out
Indicates that an Internal Auxiliary Voltage fault
condition is detected.
9.05
To restore the machine:
Turn OFF then ON the Mains Switch to restart
the machine.
DC bus overvoltage
Indicates that an Internal DC bus Overvoltage
condition is detected.
9.06
To restore the machine:
Turn OFF then ON the Mains Switch to restart
the machine.
Communication lost
All LEDs are OFF. The display shown "9.09".
Indicates that a fault condition in the
communication bus is detected.
9.09
To restore the machine:
Turn OFF then ON the Mains Switch to restart
the machine.
