    Mighty if? Mighty of?
    Please clarify what your machine actually is so I can put this in the correct section and so people may reply with the relevant info.
    Thanks.

    Hello, and welcome to the Forum.
    I'm guessing that your woes concern a Sealey MightyMIG 150/1 ?
    When you press the torch trigger, do you hear a click inside the welder? Even with no wire feed, can you still get an arc at the torch tip?
    Does the same fault happen at all selections of the power range switches?

    The fault could be due to:

    - burnt contacts on the power range switches ( or loose push-on tags at the back of those switches )
    - burnt contacts on the power-on relay ( this may be on the Control printed circuit board, in a clear plastic case )
    - loose, corroded, or burnt connections and wires inside the welder

    I would suggest unplugging the machine, removing the casing, and checking inside for the above issues.
    If they are all OK, then, as long as you are comfortable working on live mains-powered equipment, we need to start measuring voltages inside.

    Hi Eddie49 would you believe I had a look and measured the output from the transformer turned it on and it started working, must have been a loose connection

    That's good news! Probably one of the push-on tags, might be worth checking them all for tightness and full seating.
