Error messages

7.2 Error messages
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/speedometer
error
- - Shielding gas error
- x Secondary excess voltage
- x Earth fault between welding
wire and earth line
- - Fast cut-out
triggered by BUSINT X11 or
RINT X12
x - Arc break
triggered by BUSINT X11 or
RINT X12
x - Ignition fault after 5 s
triggered by BUSINT X11 or
RINT X12
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 Wire feed mechanism
overcurrent detection
x x No speedometer signal from
second wire feeder (slave
drive)
Remedy
Check the mains voltages and compare with
the connection voltages of the welding
machine
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
Check the wire feeder
speedometer is not issuing 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 the
welding wire and casing or an earthed object
Rectify error on robot
Check wire feeding
Check wire feeding
Check cable connection
Check assignment of ID numbers
Check cable connection
Inform Service
Check the wire feeding
Check the connection and particularly the
speedometer of the second wire feeder
(slave drive).
