FIMER X164 ARC(mma) small welding machine gives yellow light failure(yellow light turns on).

- The machine is running. The yellow light of the machine is on with the green light and both lights do not turn off as long as the machine works, it continues to light up as the machine runs idle.

- The fan is also working.

- When the machine is turned on, a relay closing sound is heard, when the machine is turned off, a relay opening sound is heard.

- The electrode sparks when struck on the metal, the electrode does not stick to the metal but does not weld either.

- Output voltage of the machine gives 42 volts when the probes are connected straight, and -36 volts when connected in reverse.

- Output diodes (rectifier diodes) of the machine are solid.

Considering these conditions, where do you think the failure of the machine could possibly be? Which components would you recommend I should prioritize?
