Aron;
First, let me confess that I'm no TIG welder-- gas is my speed-- but I've
read up a bit on the subject. I wonder if your tungsten electrode might be
contaminated. Try grinding a new point on the electrode and giving it
another shot.

I welded some more today. I made doubly sure the tubing was clean and the
rod, I increased the gas
pressure +5psi, and increased the post flow time as well.
That seemed to help, I think I wasn't using enough gas pressure before,
although I do think the
bottom line is the metal itself has some problems. I think another problem
is that I might be
getting contamination from the back of the weld, since this is tubing, and
I'm getting good
penetration, maybe I'm going a little too deep and loosing my shielding gas
on the back side of the
weld.
I have some tubing coming from Aircraft Spruce, so I'll assume that's good
quality, so I'll see if
the problems persist or not.
