now after al the messing and trying today was the 1st time i thought i weld 2 exhaust tubes together as i use them for my turbo kit boost pipe to the oem topmount ( for now ) honnestly i am very happy with it as the practice tig welds where al on flatbar and on mild steel this ss stuff welds totally diferent dont ask me how it just is im not experienced enough to say why i forgotten to take pics when i was actually doing it ( sorry to exited ) but took 1 from it on the pipe put back on the topmount setup i know its not the prettiest but i tested it for leaks and its not leaking so good start ha ha was at 60A + - as my yoke is not digital 1.6mm red tungsten and no filler on most just on the back where i got a little hole i dipped some filler in to save my 1st work ha ha now i touch puddle ruffly every 20 seconds was every 3 seconds when i started so progress indeed to me it seens using bigger tungsten and filler rod is easioer to weld ( for me ) let the pro welders say something on current speed etc as i am still green behind the ears with this cheers
