EN5. ERROR CODESThe machine always checks its operation automatically during start-up and reports anyfailures detected. If failures are detected during start-up, they are shown as error codes on thecontrol panel display.Error 2: Power source undervoltageThe device has stopped because it has detected a mains undervoltage that disturbs welding.Check the quality of the supply network.Error 3: Power source overvoltageThe machine has stopped the welding because it has detected momentary voltage spikes orcontinuous overvoltage dangerous to the machine in the electric network. Check the qualityof the supply network.Error 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 fan has cooled downthe machine.Other error codes:The machine can show codes not listed here. In the event of an unlisted code appearing,contact an authorised Kemppi service agent and report the error code shown.5.1 TroubleshootingProblem CauseThe main switch indicator will notlight up.• No electricity connected to the machine• Check the mains supply fuses.• Check the mains cable and plug.Poor welding results. Several factors affect the welding quality.• Ensure that the welding current selected is adequate for the selected electrode typeand size.• Ensure the cable connections are correct and secure.• Ensure the process selection is correct.• Check that the earth return clamp connection area is clean and that the cable andclamp is not damaged.• For TIG welding, check that the shielding gas flow is switched on and set correctly.Poor ignition and arc quality in TIG welding may be a result of a poorly preparedtungsten electrode. Always maintain and grind a point on the TIG torch electrode tipbefore welding.Overheating indicator is illuminated. Normally, this indicates that the device has reached its maximum designed operatingtemperature. The thermostat has become active, switching the welding power off.Allow the unit to cool and the machine will soon automatically reset and allowwelding to re-start.• Ensure that cooling air has unrestricted flow.• If the machine’s duty cycle has been exceeded, wait for indicator to turn off.In certain circumstances, this light may also indicate irregularity in the supply voltage.Too low or high supply voltage.If the machine’s malfunction is not eliminated with the above measures, contact Kemppiservice.MinarcTig Evo 200, 200MLP14
