Error codes

Error code Error description 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 limited 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 missing 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 welding load An unknown load connected to DIX connectors. 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 undervoltage DC-link voltage is too low. Check the mains voltage and/or the supply cable.
37 DC-link overvoltage 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 program data missing 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.
250 Internal memory failure Memory communication failed. Restart welding system. If problem persists, contact Kemppi service.
