    200ex amperage problems

    I bought a Longevity tig 200ex from a friend... when I'm using the torch controls, I set the amperage to what I desire , then on the machine it'll automatically raises the amperage to 200... when I switch it over to foot pedal, trying to set my amperage and the highest it will go is only up to 25amps. Is there any solutions for this problem?

    Hi Tiggamark,

    Welcome to the forum.

    I am sorry to hear about the issues with the TigWeld 200ex. The 200ex is a great machine that we haven't had a lot of issues with.

    I would suggest you call our tech support team at 87-566-4462 ext 2 or, you can email them at

    Weird issue you are having there , have you tried the machine on scratch start ? Just try to weld with the signal plug disconnected and see if you are having the same issue , secondly I believe there is a reset option of the ex units , that would probably be a good start point for you.
