| 3 | Voltage in mains network is too high. | Restart the power source. If problem persists, contact Kemppi service. |
| 4 | 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 | Power source contains an inoperative 24V power supply unit. | Restart the power source. If problem persists, contact Kemppi service. |
| 12 | Plus and minus cables are connected together. | Check the connections of welding cable and earth return cable. |
| 14 | 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. |
| 20 | 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 | 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. |
