    Trying to weld a stainless steel exhaust together, prepping the flanges, welds seems to be undercut it but if I set the amp too low it won't even melt the SS .
    any suggestions

    SS flange 304
    SS tube dunno
    filler rod 309L
    solar flux for back
    Dynasty 200DX with argon @ 65 AMP

    any suggestion I can do it better? cause cleaning the molten on back is a pain.

      More filler for sure and point the to torch towards the undercut and increase heat add filler decrease heat move over 1/8 and repeat the decrease in heat will help the metal cool so it dosent burn thru as easy. you will be layin dimes in no time!!
