It's pretty thin material--the bigger tip was just melting it back. Maybe I just need to get faster at welding!

I mean yeah the thin stuff rips but exhaust tubing ain't that skinny. Boilerplate it ain't but exhaust tubing is bread'n'butter oxy stuff because if you arc weld it you gotta go like two inches a second and that's no fun.

You need to keep the puddle from blowing through. Tap the rod into the puddle and it doesn't much matter about anything else; the trick to oxyacetylene welding is that there's enough solid under the liquid to keep it from going poof with the gas pressure. After that it's like soldering; you just feed the puddle. That gets tricky with like gas tanks but you can do it with bodywork no prob (minus the puckering of course).

If you have more exhaust shit to do it's not cheating to buy a 45 degree bend and lap-weld it.
