After the message has been output, the
machine will only function to a limited ex-
tent; the error must be corrected as quickly
as possible.
The status message can be deleted by
pressing the control knob 56.
Possible remedy
Eliminate the short-circuit (pick up
electrode holder, ...)

As long as there is an error code on display
welding is not possible.
Possible remedy
Allow switched-on machine to cool
down for a few minutes.
Replace dust filter
Check mains voltage
Connect the welding earth lead
Inform Service
Switch machine off and on again, ex-
ecute master reset
