    Hello there,

    Maybe you could understand what is happening to my MMA welder from Migatronic. It's a Pilot 200 E from the year 2002.
    Everything was fine till one month ago.
    Migatronic Pilot 200 E (2002) - No Power, Circuit Breaker Issues

    Firstly I've noticed some strange power adjustment at the knob...
    Last week it started to have some difficulty when burning at 2.5mm electrodes, and in the same day it made the circuit breaker (16amps) jumping three times.

    After this, it stopped and never got to work again. (circuit breaker doesn't even jump now)

    I've been cleaning it inside thru the years with compressed air, and I've opened it again now.
    But I can't see anything inside carbonized or with heat signs...
    220VAC power goes thru the first coil and gets to these bridge rectifiers, but can't understand what's next to follow.
    Pilot 200 E no power up

    Can you give me some tip? I will appreciate your thoughts.

    Thank you in advance.

    Regards.
    Coelho
