If failures are detected during start-up, theyare shown as error codes on the control panel display.e 2: power source undervoltageThe device has stopped because it has detected a mains undervoltage thatdisturbs welding. Check the quality of the supply network.e 3: power source overvoltageThe machine has stopped the welding because it has detected momentaryvoltage spikes or continuous overvoltage dangerous to the machine in theelectric network. Check the quality of the supply network.e 4: power source overheatingThe power source has overheated. The cause may be one of the following:• The power source has been used for a long time at maximum power.• The circulation of cooling air to the power source is blocked.• The cooling system has experienced a failure.Remove any obstacle to air circulation, and wait until the power source fanhas cooled down the machine.Other error codes:The machine can show codes not listed here. In the event of an unlistedcode appearing, contact an authorised Kemppi service agent and report theerror code shown.16 MinarcTig 180, 180MLP, 250, 250 MLP
