    Thanks for the help.
    Be patient... it takes a lot of practice to develop the Hand and Rythm.. kinda like dancing...

    Progress might be easier if you spent some time studying the basics in the TIG Guidelines pamphlet .... that is if you have not already done so..

    The Resource section also has a lot of TIG info as well .... the videos might illustrate the points better than the written word...

    additional good stuff at "WeldingTipsandTricks" and "YouTube"

    Well, its starting after comming close to the work, so we know the high freq is working. So open open the bottom flap, in there where you hook up your cables, gas and such there is a High freq dial, merely turn that dial to max, then the Freq should come on full blast. Might want to set the High freq pont gaps to like 12 Thou then it'll really dance.

    Seems to work now

    Got the chiller and Argon hooked up and after a little tinkering, it seems to be working. Now I just need to learn how to TIG weld...... Shouldn't take more than a night right?.?.?

    I am not 100% sure the High Frequency is working, I have not tried to weld aluminum yet, just steel, but I did have the Hi Freq start on and it seems like I still need to scratch start it or at least come very close to scratching to start the arc.

    How can I (someone who knows very little) confirm that the Hi Freq is working?

    Good idea. Thanks.
    This machine and three twin sisters sat outside under tarps for a few years..... No wonder it was nasty.
    Anyone in the Upstate NY area looking for one, I can get you in contact with the guy who rescued these from the scrap yard. He probably wont give them all away, but pretty close.
    I'll keep you all posted on my progress.

    Well, thats good news, now get yourself some preferably "MG chemicals" silicone grease, (dielectric grease) and stuff some into all those molex connections on the board, to prevent the corrosion from happening again.

    Fixed....maybe.

    I pulled the PC board out and cleaned the terminals. Cleaned all the connections to the relay that was firing when I hit the pedal, and low & behold, it seems to work.
    I have to get chiller and gas hooked up then I will test it more.

    Thanks for the help.

    Any way I can test it separately?
    how do I identify it?

    I metered the output studs with the HF Turned off, and show zero volts output.
    I tried it on ac&dc, str&rev polarity, and high&low range.
    Tried it with current control switched to panel as well as remote.
    I can hear the gas solenoid open & close and I can hear & feel one of the contactors open & close.
    The contactor is not controlling gas as it closed as soon as you let off the pedal and the gas solenoid closes after the post flow timer times out.
    That's about all I can tell you right now.
    Any clues on where to look next?
    I have cleaned & gapped the HF to .008".

    ok, then your going to have to either meter the output studs, or stick weld with it.

    I don't have gas hooked up, but I can hear the solenoid snap open when you step on the pedal and close when you let off.
    I played with the post flow and that seems to work correctly.

    I do not have the pre flow option.

    Apparently its an option, if its there, it'll be to the left of the on/off switch.
    Does gas flow when you hit the pedal, and does it shut off when you release the pedal?

    Is there an adjustment for pre-flow?
