Rectifying faults
All products are subject to rigorous production checks and final checks. If, despite this, something fails to
work at any time, please check the product using the following flowchart. If none of the fault rectification
procedures described leads to the correct functioning of the product, please inform your authorised dea-
ler.
5.1
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.
Error message
Possible cause
Remedy
Err 1
Water fault
Only occurs if a water cooling
unit is connected.
Ensure that sufficient water pressure can be built
up. (e.g. top up water)
Err 2
Temperature error
Allow machine to cool down.
Err 3
Electronics error
Switch machine off and on again.
If the fault persists, inform the service depart-
ment.
Err 4

see "Err 3"
Err 6
Balancing error in voltage record-
ing.
Switch machine off, place the torch on an insula-
ted surface and switch on again.
If the fault persists, inform the service depart-
ment.
Err 7
Balancing error in current record-
ing.
Switch machine off, place the torch on an insula-
ted surface and switch on again.
If the fault persists, inform the service depart-
ment.
Err 8
Error in one of the electronics
supply voltages or excess tempe-
rature of the welding transformer.
Allow machine to cool down. If the error message
persists, switch the machine off and back on
again.
If the fault persists, inform the service depart-
ment.
Err 9
Low voltage
Switch off the machine and check the mains vol-
tage.
Err 10
Secondary overvoltage
Switch machine off and on again.
If the fault persists, inform the service depart-
ment.
Err 11
Overvoltage
Switch off the machine and check the mains vol-
tage.
Err 12
VRD (open circuit voltage reduc-
tion error)
Inform Service
