Error descrip-
tion
Possible reason
Proposed action
1
Power source
not calibrated
Power source calibration has been lost.
Restart the power source. If problem persists, contact
Kemppi service. Note: The equipment operation is lim-
ited when this error occurs.
2
Too low mains
voltage
Voltage in mains network is too low.
Restart the power source. If problem persists, contact
Kemppi service.
3
Too high mains
voltage
Voltage in mains network is too high.
Restart the power source. If problem persists, contact
Kemppi service.
4
Power source is
overheated
Too long welding session with high power.
Do not shut down, let the fans cool the machine. If
fans are not running, contact Kemppi service.
17
Phase is miss-
ing from mains
supply
One or more phases are missing from the
mains supply.
Check the mains cable and its connectors. Check the
voltage of mains supply.
20
Power source
cooling failure
Cooling capacity is reduced in the power
source.
Clean the filters and clear any dirt from the cooling
channel. Check that the cooling fans are running. If
not, contact Kemppi service.
24
Cooling liquid
overheated
Too long welding session with high power
or high ambient temperature.
Do not turn off the cooler. Let the liquid circulate until
the fans cool it down. If fans are not running, contact
Kemppi service.
26
Cooling liquid
not circulating
No cooling liquid or circulation is blocked.
Check the liquid level in the cooler. Check hoses and
connectors for blockage.
27
Cooler not
found
Cooling is turned on in the settings menu,
but cooler is not connected to power
source or cabling is faulty.
Check the cooler connections. Ensure that the cooling
is turned off in the settings menu, if the cooler is not in
use.
34
Unknown weld-
ing load
An unknown load connected to DIX con-
nectors.
Remove any unintended resistive load connected to
the welding equipment and restart the power source.
35
Too high mains
current
Current drawn from the mains is too high.
Reduce welding power.
36
DC-link under-
voltage
DC-link voltage is too low.
Check the mains voltage and/or the supply cable.
37
DC-link over-
voltage
DC-link voltage is too high.
Check the mains voltage.
38
Mains voltage
too high or too
low
Mains voltage is too high or too low.
Check the mains voltage and/or the supply cable.
40
VRD error
Open circuit voltage exceeds the VRD limit.
Restart the power source. If problem persists, contact
Kemppi service.
80
Torch cooling
required
Water cooled torch is connected but the
cooler is turned off.
Turn the cooler on in the settings menu or change the
torch to an air cooled model.
81
Welding pro-
gram data miss-
ing
Welding program data has been lost.
Restart the power source. If problem persists, contact
Kemppi service.
244
Internal
memory failure
Initialization failed.
Restart welding system. If problem persists, contact
Kemppi service.
