Error messages (power source)

A welding machine error will be signalled by an error code (see table) on the control display. In
the event of an error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
• Document machine errors and inform service staff as necessary.
• If multiple errors occur, these are displayed in succession.

Rectifying faults
Error messages (power source)
Remedy
Check the mains voltages and compare with
the welding machine connection voltages
Allow the machine to cool down (mains
switch to "1")
Fill coolant
Turn on pump shaft (coolant pump)
Check air cooling unit overcurrent trip
Check the wire feeder
Tachogenerator is not emitting a signal,
M3.51 defective > inform Service.
Check shielding gas supply (for machines
with shielding gas monitoring)
Inverter error > inform Service
Separate the electrical connection between
welding wire and casing or an earthed object
Rectify error on robot
(Interface for automated welding)
Check wire feeding
(Interface for automated welding)
Check wire feeding
(Interface for automated welding)
Check the emergency stop switch at the
interface for automated welding
Check cable connections
Correct ID numbers > see 5.2.2.6 chapter
Check cable connections
Inform Service.
Check ease of wire feeding
Check the connection and particularly the
tachogenerator of the second wire feeder
(slave drive).
Check mains voltages
Check machine usage > see 3.2 chapter
Inform Service.
