Possible cause
Proposed action
1
Power source
not calibrated
Power source calibration has been lost.
Restart the power source. If problem persists, contact
Kemppi service.
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
5
Internal 24V
voltage is too
low
Power source contains an inoperative 24V
power supply unit .
Restart the power source. If problem persists, contact
Kemppi service.
7
Wire feeder not
found
Wire feeder is not connected to power
source or connection is faulty.
Check the control cable and its connectors.
9
Measurement
cable failure
Voltage sensing cable is not connected to
the work piece or measurement cable con-
nection is faulty.
Connect voltage sensing cable to the work piece and
check the measurement cable and its connectors.
11
FET unit failure
Power source contains an inoperative FET
unit.
Restart the power source. If problem persists, contact
Kemppi service.
12
Welding cable
failure
Plus and minus cables are connected
together.
Check the connections of welding cable and earth
return cable.
13
IGBT overcurrent
Inoperative mains transformer in power
source.
Restart the power source. If problem persists, contact
Kemppi service.
14
IGBT overheated
Too long welding session with high power
or high ambient temperature.
Do not shut down, let the fans cool the machine. If
fans are not running, contact Kemppi service.
17
Phase is missing
from mains sup-
ply
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.
33
Welding cable
calibration fail-
ure
Welding cable calibration failed.
Check the welding system cables and their con-
nections.
