If I was you I would just get rid of that TIG machine. Send it to me. I could always use another. Take up needlepoint instead. Even better, keep TIG welding because your weld looks fine and your welds will only get better. I know, you will get a lot of nit-picking advice, which is fine, but your weld bead really looks better than many of the beads I see done by folks who weld for a living. There is a little difference in travel speed and it looks like the shielding gas may have been blown away in one spot, but that could just be the camera. I'm pretty sure you know already where the weld bead is not ideal and don't need anybody here to tell you. But to reiterate you bead is pretty good and if you did that bead for me and I was paying for the work I wouldn't complain.
