You can watch some YouTube vids to start. Buy a cheap used 110 mig and start practicing. You will pick it right up. I have taught a bunch of people. What I've noticed is once they overcome the typical hype that it is too hard, it only takes about 20 min to understand the basics and start laying down some good beads. You can do it!! Get some good under hood time on a practice table and you'll be good to weld on your car in 1 weekend
