  • More Econotig issues...., arc issues, no amperage control

    Hi, New to the forums here. Been reading everything I can on these econotig issues. Mine seems to be just a tad but different, or maybe not.

    First off I only use my machine for tig.. I replaced all torch components. Running I think the new purple tungsten. Airgas set me up with saying it will do alum/ and steel. regulator is at 20, tank is nearly full.

    I seem to have couple issues. My high freq works half the time, could be ground.

    It seems like it does not have enough oomph to even start a puddle, on 1/16-1/8" steel or aluminum. It barely has enough to melt the filler.

    Now If I crank it all the way up to 100% on the dial or all the way down the outcome is the same, not enough to start a puddle on steel. With my pedal I don't have any control either. Wide open or the very least the control does not differ. Like on or off.

    Thanks PRAXAIR wants $180 to send it out, + any more after that you won't know until you get the bill............ F-THAT !!

    Sounds like your PC1 arc start board is pooched.

      I'm assuming this is the $300-400 board that I've been reading about?

      Dumb question but what would be the best course of action?

      Weird tho I seemed to be able to weld Or what I assume to be welding cuz I used some filler up, lol some 1/8th

      aluminum last night. Seemed like i had to move really really fast. But on some mild

      steel I can't get a puddle to start? DCEN is what I was on for steel
