Questions and answers
Turns on, yellow caution light on, after self test main switch trips and my 50 amp breaker in panel.
The yellow caution light turns on and the main switch trips on the AHP WELDS alphaTIG 203Xi due to a short circuit or overload. This indicates a severe problem or fault in the system. The main circuit breaker in the panel box may also trip. The power supply should be checked for proper wiring and grounding.
