Reply:Pure tungsten works quite well, Ive used it numerous times.Have we all gone mad?
Reply:Craig,I only use pure tungsten when AC welding on aluminum.  Most of us dinosaurs do.  You can use 2%, lots of guys do, but old habits die hard.  When I weld aluminum DCSP, I use 2% and point it.I r 2 a perfessional

Reply:Very nice weld.  Thin Al like that has got to be very difficult.Seems like the 75% He could add too much heat for something so thin, and also tend to make the arc more unstable.  Guess you didn't have any problem with it.
