It’s easier for me to tack in place with the Mig, then gas weld. I have a 3-1 machine that has Tig, I’m just not good enough to use it on light gauge metal. With a O/A I can come “in and out” and control things. My 3-1 doesn’t have a foot pedal so I .For thin sheet metal welding it can be 30 ampere while for thicker (e.g. 1/8” square groove weld)- it can go up to 220 ampere for example. GMAW-S gives low heat and makes it easy to use in all positions on sheet metal, low .
