Error messages (power source)

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.

Possible cause
b) c)
- x Mains overvoltage
- x Mains undervoltage
- - Welding machine excess
temperature
x - Low coolant level
- - Wire feeder/tachometer error
- - Shielding gas error
- x Secondary overvoltage
- x Earth fault between welding
wire and earth line
- -
Fast cut-out
Triggered by BUSINT X11 or
RINT X12
x - Arc interruption
Triggered by BUSINT X11 or
RINT X12
x - Ignition error after 5 s
Triggered by BUSINT X11 or
RINT X12
- - Emergency stop deactivation
x - Wire feeder not detected.
Control cable not connected.
Incorrect ID numbers
assigned during operation
with multiple wire feeders.
x - Wire feeder 2 not detected.
Control cable not connected.
- x
VRD (open circuit voltage
reduction error).
x x Excess current detection on
wire feeder
x x No speedometer signal from
second wire feeder (slave
drive)
- x Mains phase failure
Remedy
Check the mains voltages and compare with
the welding machine connection voltages
Allow the machine to cool down (mains
switch to "1")
Top up the coolant
Leak in the coolant circuit >
repair the leak and top up the coolant
Coolant pump is not working > check excess
current trigger on air cooling unit
Check the wire feeder
Speedometer 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 connection between welding
wire and casing or an earthed object
Rectify error on robot
Check wire feeding
Check wire feeding
Check the emergency stop circuit at the
interface for automated welding
Check cable connections.
Check ID number assignation
Check cable connections.
Inform Service.
Check wire feeding
Check the connection and particularly the
speedometer for the second wire feeder
(slave drive).
Check mains voltages
