Error codes
In error situations, the control panel displays the number of the error. Refer to the table below for more information on the error situation.
| Error | |||
|---|---|---|---|
| Code | Title | 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. |
| 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 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. |
| 33 | Welding cable calibration failure | Welding cable calibration failed. | Check the welding system cables and their connections. |
| 40 | VRD error | Open circuit voltage exceeds the VRD limit. | Restart the power source. If problem persists, contact Kemppi service. |
| 43 | Overcurrent in wire feeder motor | There may be too much pressure in the wire feed rolls or dirt in the wire line. | Adjust the feed roll pressure. Clean the wire line. Change worn parts in the welding gun. |
| 44 | Wire speed measurement is missing | Faulty sensor or wiring in wire feeder. | Restart the welding system. If problem persists, contact Kemppi service. |
| 62 | Power source not found | No power source is connected to the wire feeder, or connection is faulty. | Check the control cable and its connectors. |
| 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 (%sub:%device). | Restart welding system. If problem persists, contact Kemppi service. |
| 250 | Internal memory failure | Memory communication failed (%sub:%device). | Restart welding system. If problem persists, contact Kemppi service. |
