    Default flakey Syncrowave 200

    I have a Syncrowave 200 that is acting flakey on me. I am welding aluminum on AC 175A 7.5 balance. Sometimes the welder acts perfectly normal, other times I push the pedal, pre-gas starts, then I hear a hum but no spark. I let off the peddle and get post flow.

    Why no spark?

    What information have I left out?
    Thanks for your help.

    First I would check your ground. Then I would rub the tungsten on the table before starting, as the tip can get glazed. Then I would check your point gaps.

    Good Luck.

    Ding ding ding, we have a winner! Apparently vandals are breaking into my shop and contaminating my tungsten. Thanks for all your help, I was just sure it would be something major,since I bought this used with only 4 hrs on it.
