    Re: Homemade Arc inverter welder And Plasma cutter power

    Hello devreci,
    I have to say one thing, you are very brave doing the circuit on veroboard, especially
    since the circuit is so complex.
    I have to also say you've done an excellent job. Not only on the PCB, but also the transformer
    and the rest of the set up.
    Well done!!!
    Regards,
    Relayer

    Re: Homemade Arc inverter welder And Plasma cutter power

    Thanks.

    I am interested in electronics as hobby.

    If I work gently, it will be torture, not entertainment.

    This device (plasma cut) is very expensive in my country. 3 minimum wage.



    I fixed the errors in the circuit drawing.
