Will, you're using way too much rod. push the puddle with your heat and don't add so much filler. If you have tight seams you should be able to tig with no filler rod (not that you need or want to for this though). Another trick, assuming you are running shielding gas is to put a T in your gas line and pump the inside of the muffler full of Argon too.
Thanks man, I could use all the tips I can, I'm so used to mig welding. About how far should the tip be from the weld?
