What should I do if the machine overheats and stops outputting current?

If the unit overheats, the thermostat (TP1) opens, output stops, and the fan continues running — allow the fan to run with the torch trigger released until the unit cools and the thermostat resets. The overheat indicator light will flash when this occurs. Reduce amperage or duty cycle before resuming welding. (Pages 8 and 26)
