Possible reason
Power source calibration has been lost.
Voltage in mains network is too low.
Voltage in mains network is too high.
Too long welding session with high power.
One or more phases are missing from the
mains supply.
Cooling capacity is reduced in the power
source.
Too long welding session with high power
or high ambient temperature.
No cooling liquid or circulation is blocked.
Cooling is turned on in the settings menu,
but cooler is not connected to power
source or cabling is faulty.
An unknown load connected to DIX con-
nectors.
Current drawn from the mains is too high.
DC-link voltage is too low.
DC-link voltage is too high.
Mains voltage is too high or too low.
Open circuit voltage exceeds the VRD limit.
Water cooled torch is connected but the
cooler is turned off.
Welding program data has been lost.
Initialization failed.

Proposed action
Restart the power source. If problem persists, contact
Kemppi service. Note: The equipment operation is lim-
ited when this error occurs.
Restart the power source. If problem persists, contact
Kemppi service.
Restart the power source. If problem persists, contact
Kemppi service.
Do not shut down, let the fans cool the machine. If
fans are not running, contact Kemppi service.
Check the mains cable and its connectors. Check the
voltage of mains supply.
Clean the filters and clear any dirt from the cooling
channel. Check that the cooling fans are running. If
not, contact Kemppi service.
Do not turn off the cooler. Let the liquid circulate until
the fans cool it down. If fans are not running, contact
Kemppi service.
Check the liquid level in the cooler. Check hoses and
connectors for blockage.
Check the cooler connections. Ensure that the cooling
is turned off in the settings menu, if the cooler is not in
use.
Remove any unintended resistive load connected to
the welding equipment and restart the power source.
Reduce welding power.
Check the mains voltage and/or the supply cable.
Check the mains voltage.
Check the mains voltage and/or the supply cable.
Restart the power source. If problem persists, contact
Kemppi service.
Turn the cooler on in the settings menu or change the
torch to an air cooled model.
Restart the power source. If problem persists, contact
Kemppi service.
Restart welding system. If problem persists, contact
Kemppi service.
