7.2 Error messages (power source)
A welding machine error is indicated by an error code being displayed (see table) on the
display on the machine control.
In the event of a machine error, the power unit is shut 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.
Check the mains voltages and compare with
the connection voltages of the welding
machine
Welding machine excess
temperature
Allow the machine to cool down (mains
switch to "1")
Top off the coolant
Leak in the coolant circuit >
rectify the leak and top off the coolant
Coolant pump is not working > check excess
current trigger on air cooling unit
