Honestly, Trying to get it figured out with a MIG is totally different then a TIG. If you scribe tight light to trim and fit you can tack it up with the MIG. But learning how to weld sheetmetal is like trying to learn how to ride a bicycle when you want to ride a unicycyle. Just start now with the tig on 20amps and maybe buy some MIG wire to not build up your welds to much while your learning. The TIG welders out number MIG welders 5-2 in my shop and all my MIG welders are 110 volt except 1. I have 1 220 volt MIG.
Spend your time learning how to trim and fit sheetmetal very tight. Then learn to tack with the TIG.
Learn to cut gap and fit like this
