What to do if Miller Si 160 has no weld output and the high temperature light is on?

If your Miller Welding System's high temperature light is on and there's no weld output, it could be due to the unit overheating and undergoing thermal shutdown. Allow the unit to cool with the fan on. Alternatively, reduce the duty cycle or amperage. Also, check for and correct any blocked or poor airflow to the unit.
