What to do if my ESAB Welding System has no power or no arc?

If your ESAB Welding System shows no power or arc, verify that the main switch is turned on. Also, check the display for a temperature fault, and see if the system breaker has tripped. Ensure that the input power, welding, and return cables are correctly connected, and that the correct current value is set. Finally, inspect the input power supply fuses.
