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.
