Error
Code Title Possible cause Proposed action
1
Power source
not calibrated
Power source calibration has been lost. Restart the power source. If problempersists, contact
Kemppiservice.
2
Too low mains
voltage
Voltage in mains network is too low. Restart the power source. If problempersists, contact
Kemppiservice.
3
Too high
mains voltage
Voltage in mains network is too high. Restart the power source. If problem persists, contact
Kemppiservice.
4
Power source
is overheated
Too long welding session with high power. Do not shut down, let the fans cool themachine. If fans are
not running, contact Kemppi service
5
Internal 24V
voltageis too
low
Power source containsan inoperative24V
powersupply unit .
Restart the power source. If problempersists, contact
Kemppiservice.
7

not found
Wirefeeder is not connected to power source
or connection is faulty.
Check the controlcable and its connectors.
9
Measurement
cablefailure
Voltage sensing cable is not connected to the
work piece or measurement cableconnection is
faulty.
Connect voltagesensing cable to thework pieceand
check the measurement cableand its connectors.
11
FET unit failure Power sourcecontains an inoperative FET unit. Restart the power source. If problempersists, contact
Kemppiservice.
12
Welding cable
failure
Plus and minus cables areconnected together. Check the connections of welding cable and earth return
cable.
13
IGBT over-
current
Inoperative mains transformer in power source. Restart the power source. If problempersists, contact
Kemppiservice.
14
IGBT over-
heated
Too long welding session with high power or
high ambient temperature.
Do not shut down, let the fans cool themachine. If fans are
not running, contact Kemppi service.
17
Phaseismiss-
ing from
mains supply
Oneor more phases aremissing from the mains
supply.
Check the mains cableand its connectors. Check the
voltageof mains supply.
20
Power source
cooling failure
Cooling capacity isreduced in the power
source.
Clean the filters and clearany dirt from the cooling channel.
Check that the cooling fans are running. If not, contact
Kemppiservice.
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 levelin thecooler. Check hoses and con-
nectors for blockage.
27
Cooler not
found
Cooling isturned on in the settings menu, but
coolerisnot connected to power sourceor
cabling is faulty.
Check the cooler connections. Ensurethat 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 connections.
