Error messages
Faults during welding
Fault Possible cause Remedy

System error Turn o the device. If all indicators have gone out,
wait at least 1 more minute in switched-o state.
Switch the machine on again. If the fault persists,
contact Service
Fault LED [8] is lit
constantly
CDF exceeded, machine is overheating Leave the machine switched on and allow to cool
Displays remain dark Mains fuse defective Replace the fuse
Neutral conductor, mains phase missing Check mains cable/mains extension cable
No welding current Ground cable not connected or defective Check the ground cable and replace, if necessary
Electrode holder or welding torch not
connected or defective
Check the electrode holder or welding torch and
replace, if necessary
The electric arc does
not strike
No or bad ground contact Ensure earthing contact is good
Wrong electrode diameter Select the right electrode diameter
Welding current set too low Set welding current higher
Tungsten electrode dirty or incorrectly
ground
Grind correctly or replace the electrode, if necessary
Gas ow rate set incorrectly Set gas ow rate correctly
No shielding gas Gas cylinder empty Replace the gas cylinder
Pressure reducer defective Check, replace if necessary
Gas valve on welding torch not open or
defective
Check, replace if necessary
