Possible cause / remedy
The inductance of the welding circuit is too high for the selected
welding task.
Check WF configuration.
One of several partial inverters is not supplying welding current.
Check temperature and switching thresholds.
The actual value of a welding parameter is outside the specified
tolerance field.
The resistance in the welding circuit is too high. Check earth
connection.
Switch the machine off and on. If the error persists, notify Ser-
vice.
The power limit of the mains fuse is reached and the welding
power is reduced. Check the fuse setting.
Check the gas supply.
Check the gas supply.
Check the gas supply.

Fault of wire feeder - permanent overload of the wire drive.
Excess current detected on wire feed motor.
JOB Selection was not carried out because the JOB number is
unknown.
Excess current detected on wire feed motor slave (push/push
system or intermediate drive).
Fault of wire feeder - permanent overload of the wire drive
(push/push system or intermediate drive).
Wire feeder not connected (reset by actuating the automatic cir-
cuit-breaker of the wire feed motor).
