At work we use a welding rod especially made for removing broken bolts/studs. We buy them from Lawson, it really saves our bacon with the Sterling trucks, they break exhaust manifold studs like crazy. And almost never flush or proud, always break below surface ugghh!
Back in high school the teachers told us to drink milk if we got galvi sick lol. And put wet tea bags on our eyes if we got flashed. I used to weld for a fence company and welded a ton of galvanized pipe. Exhaust fan and respirator and don't put your face over the plume and I could do it 12hrs a day...

There is no secret way to remove it that we have found, we prep the same as you do, acetone and wire brush, etc.

Your welds look great for first time. I haven't even used the pulse on mine yet lol!
These guys already said it better than I could, but they are so right, practice is key to TIG welding. After a while you will get pretty good at it and then you will look at these pics and you will be able to see what's wrong and then how to fix it.
I have an HTP Invertig 221 and I sharpen to a sharp point also on A/C, usually 3/32 2% Lanthanated and it will form a small ball at the end after a while. As long as the ball stays small and the bead narrow, I just leave it. The arc stays very stable even with slightly balled electrode. I was using ...
