    I would still TIG it....

    you can keep heat input to reasonable levels..... by keeping your amps high and moving fast...

    you will only cook it by having amps too low and moving too slowly

    So.......... pour the coal to it and move like the wind...

    Just my 2cnts worth

    I would run this one stick. you will spend a lot of time, rod & gas and put some serious heat into the piece if you TIG it. Stick will give you a deeper penetration (just make sure your dig setting is 100%) and will be a lot faster and less consumables.

    Unless you can't stick, in that case. TIG away at 200 A and just balance the pedal as you go. Gonna take some heat though, clamp it well.

    That's exactly what I did for my bender stand. No need to set up the tig and play with settings. I used 1/4" flat bar to make the "tube" (because I already had the flat bar) with my Millermatic 211, and welded to a 1/2" thick base with stick. Popped in some 1/8" 5P+ 6010 on the tig, laid a bead all around. Wasn't satisfied with the fillet size, so I went over it with 1/8" 7018 excalibur. that reminds me, I should paint it before it gathers any more surface rust. Been humid here in south Texas lately.

    Yup, with a pipe wall thickness of 200-thou and a baseplate thickness of 500-thou, you're gonna need all 200A. Number of passes would depend on what size fillet you are aiming for.

    I tend to set the machine higher and modulate the heat with the foot pedal...

    soo... I would set the Dyn for 200 amps and go from there.. depending on positioner speed and your personal welding style....

    it might be an old fahioned approach... but works for me....

    Punch it at full 200 amps. Adjust with your foot control or positioner speed as required.

    I would make sure the throat of the weld is at least as deep as the thickness of the pipe wall.

    Need a Tig recommendation

    I would like a recommendation on the amperage setting I should use to weld a pedestal for a JG2 32 tube bender?

    The base plate is 12 inches square and 1/2 inch thick.
    I am welding a 36 inch length of 2-1/2 schedule 40 pipe to the base plate.

    My equipment and set up is as follows:
    Dynasty 200 with Argon and set to DC.
    WP20 torch with gas lens and 1/8 2% Lanthanated Tungsten.
    1/8 inch ER70S filler rod

    I have the base plate and pipe mounted on my rotary positioner, so doing the weld should be easily done.

    Amp setting to use?
    How many passes should I make around the pipe?

    Thank you for comments and help.
