Mig is the easiest to learn for the type of welding you will do. Stick welding has very limited use on cars. Tig welding is more versatile but is more of a specialty ( stainless, cast aluminum ). The mig welder is the workhorse of every automotive bodyshop, muffler shop, and service dept. Set up with .023 wire, 75% argon/25%co2 mix and some instructional videos, you will be welding in no time.
