  If there's no weld output and the high-temperature light is on, it could be due to several reasons. The welder may have overheated, so allow the unit to cool down with the fan on. Alternatively, the duty cycle or amps might be too high, so reduce them. Lastly, airflow might be blocked; clean the vents and fan with compressed air.

  If there is no weld output but the ready light is on, it could be due to a loose weld cable or an improper ground clamp connection. Ensure the weld cable connection at the welder is tightened. Also, make sure the area where the ground clamp is attached is clean, exposed metal, and free of dirt, paint, and oil.

  The main supply fuse might be shutting off frequently because the circuit breaker has too low amperage. Install a dedicated 25 amp circuit breaker to resolve this issue.
