Why is the output terminal over-temperature on my ESAB Fabricator EM 400i Welding System?
If the ESAB Welding System's output terminal is overheating, ensure the OKC terminal and welding cable are properly connected. Use cables with the correct cross-sectional areas and select a suitable cable OKC. Also, check the fan to ensure the blades are not obstructed.
What to do if my ESAB Fabricator EM 400i Welding System shows abnormal input power?
If your ESAB Welding System displays abnormal input power, verify that the input cables are properly connected and that all three input phases are present.
Why is the IGBT or diode over-temperature on my ESAB Welding System?
If your ESAB Welding System's IGBT or diode is overheating, make sure you are not exceeding the rated duty cycle range. Check that the air vent of the housing is not blocked and that the fan blades are not stuck.
What causes an input power fault in my ESAB Fabricator EM 400i Welding System?
If you experience an input power fault with your ESAB Welding System, verify that the input cables are properly connected and that the input power is normal.
How to troubleshoot poor welding performance on my ESAB Fabricator EM 400i Welding System?
If you are experiencing poor welding performance with your ESAB Welding System, check that the welding current supply and return cables are correctly connected. Also, check that the correct current value is set, the correct welding wires are being used, and the main power supply fuses are in working order.
What causes output overvoltage in my ESAB Fabricator EM 400i Welding System?
If your ESAB Welding System's output is overvoltage, verify that the input voltage is normal and that the output cables are connected correctly.
Why does the thermal protection trip frequently on my ESAB Welding System?
If the thermal protection trips frequently on your ESAB Welding System, ensure that you are not exceeding the rated data for the power source (i.e. that the unit is not being overloaded). Also, check that the ambient temperature is not above the one for the rated duty cycle 40°C/104°F.
What to do if my ESAB Fabricator EM 400i Welding System shows output overcurrent?
If your ESAB Welding System displays output overcurrent, verify that the output is not short-circuited.
Why is the welding current interrupted during welding with my ESAB Welding System?
If the welding current is interrupted during welding with your ESAB Welding System, check whether the thermal protection trip has operated (indicated by the orange LED on the front).
What to do if there is a button error on my ESAB Welding System?
If you are experiencing a button error on your ESAB Welding System, check the button and make sure it does not stick.
