After 30 minutes of pratice.

admin

Never used a TIG machine. So I bought one, and the only thing I had on hand was a piece of aluminum. So after 30 minutes or so this is what I got. I know that my a/c balance way off. But I'll fix that later. Attached ImagesMillermatic 211PowerPlasma 50s
Reply:Your filler looks reasonably consistent, but your weld looks cold. That's very typical of someone who's never tig welded and is trying to do alum.If you are looking for suggestions, you need to post up your machine, settings, tungsten size, filler size, material thickness etc so we can make some useful suggestions..No government ever voluntarily reduces itself in size.

Reply:1/16th is good to around 140a depending on balance. If you dip lower than 60% or so, at 140A, you might split your tungsten or have it melt back. That's when you'd go to the next larger size tungsten... If yours didn't ball up all the way inside your cup, or melt off into your weld bead, you don't need to go up.Miller: 200dx, Bobcat 225, Passport, Powermax 45, Milwaukee: Dry Saw, MagDrill, grinders
