mickmate,

Exhaust system and general Welding, have just bought a Miller 150STH Tig welder!
I havent done much Tig work for a few years and then I was no expert, used to weld stainless steel tubed kite buggies for export! Since having the welder (2-3 weeks) have done a heap of practise, used most of a medium sized bottle of Argon. I am finding working on steel 1/8" and under with 1.6mm 6500 mild steel copper coated welding wire, providing I sand the metals first, the welds are turning out ok, but its easy to get a bit hot and undercut, hence I am finding "JUST" melt and keep dabbing the filler rod!!

This Tig Torch has a variable slide amperage control on the hand piece, which is quite good, I have just ordered the flexi head and Gas saver screen and shorter cup for tight spacers. Getting the welds tidy is another story but with my headers I have noticed it just melts through the inside using the above technique, but if I juice it then it leaves a bit to much of molten ring on the inside of the pipe!
