Troubleshooting
No welding current

Cause:
Remedy:
No welding current
After the machine is switched on, all indicators are permanently lit up (longer than 2
seconds)
Cause:
Remedy:
Poor ignition characteristics in rod-electrode welding
Cause:
Remedy:
Arc sometimes breaks during welding

Cause:
Remedy:
Rod-electrode sometimes sticks
Cause:
Remedy:
Mains fuse and/or safety cut-out has tripped
Cause:
Remedy:
Cause:
Remedy:
Loud bang
in some cases the mains fuse or automatic circuit-breaker is tripped as well
Cause:
Remedy:
Fault in power module
Switch machine off and back on again; if the error keeps on occurring -
send machine in for service
Short-circuit (secondary side)
Stop the short-circuit (disconnect the rod-electrode cable or earthing
cable from the current socket with the bayonet latch. If the error keeps on
occurring - send machine in for service
Wrong welding process selected
Select the welding process "Rod-electrode welding" or "Rod-electrode
welding with CEL-electrode"
If the TIG welding process is selected, the TIG comfort-stop parameter is
set to too low a value
In the set-up menu, set the TIG comfort-stop parameter to a higher value
Arc-burning voltage of electrode too high (e.g. grooved electrode)
If possible, use different type of electrode or a machine capable of deliver-
ing greater welding current
Mains undervoltage
Measure mains voltage on machine, increase the cross-sectional area of
the supply lead
Wrong welding process selected
Select the "TIG welding" or "TIG pulsed arc welding" process
"Arc-force" parameter (Rod-electrode welding) or "Characteristic" parame-
ter (Rod-electrode welding with CEL-electrode) is set to too low a value
In the set-up menu, set the "Arc-force" parameter (or "Characteristic"
parameter) to a higher value
Mains fuse too weak; incorrect safety cut-out
Insert correct fuse (see technical data)
Mains fuse is tripped under no-load conditions
Machine should be serviced
Varistor (overvoltage protector) has been tripped; mains voltage error
Replace the varistor - may only be done by skilled, trained personnel -
otherwise send machine to After-Sales Service
