    260 amps is Way too much for a 3/32" tungsten. You should only need about 150 amps, max! You can bevel the tubing and do mulitiple passes to fill it but you probably only need one pass. You could also do a wash pass and add filler at both sides of the "wash" movement. Just grind any mill scale off the johnny joint first.

    my two cents...

    oh i screwed up i meant 1/8 orange tung!!

    ok so educate me on the wash pass? since my machine is only a 200a machine i dont think i can make the weld but i know the inverter machines will run lower amps.

    thanks again for all the help!!

    That 200DX will easily weld that!

    I welded this yesterday,

    2"x3"x 3/16"wall square tube welded to 3" x 1/2"wall round with my 200DX - 3/32 tung at 160 amps - more than enough!

    TS-OFF-ROAD,
    that is INSANE!!!
    I'm hoping to get my contractor's kit soon for my new Dynasty 200DX (air cooled torch). I want to weld 1/4" thick aluminum square tubing for a truck rack. someone told me I'd probably use about 175 amps to do it. I'm guessing that would put me in the 20% duty cycle range. Can you tell me what type tungsten/size and other info you would try?
    thanks,
    bert
