If you exceed the machine’s duty cycle, the transformer will overheat. The safety circuit will trip, stopping the welding output while keeping the fan running. If this light turns on, stop welding and leave the machine turned on for 10–15 minutes to cool down. Dual Capabilities: Gas vs. Gasless (Flux-Cored) Setup
