Steel is welded in DCEN, but when welding aluminum, use AC. Also, to prep your tungsten tip, put the unit on DCEP and strike a short arc on your work piece. This will melt the tip to a nice ball w/ a dia. of about 1 1/2 the thickness of the tungsten. Don't forget to put it back on AC though when your done, or you'll melt the torch.

One question...
I was taught how to TIG with this same machine (at LOLHS), and IIRC, we were welding in DCEN... Am I just mistaken? (I haven't TIGed since the 2008 build season  ) |
