/diy/ - Do It Yourself

If you only care about doing good work efficiently get a MIG machine with gas, not flux core. 120v is fine for anything on a passenger car, including frame if you do multiple pass (not ideal but possible, as long as it's not a full box pickup frame or anything like that). Best would be getting a Miller/Lincoln machine that can do both 120 and 240, then if you end up doing heavier work later you can worry about adding a dedicated line to your garage. If you want to actually learn to be good at welding you can start with oxy acetylene, but it's not great to store in a garage and it's going to be much more difficult. You can absolutely TIG on auto body, IDK what that other poster is talking about, it's just not very efficient. TIG is the best of both worlds for versatility and actually learning to be good at welding, but it's expensive. Any of the 3 options are fine, but most people will just go MIG because it's very easy and fairly cheap.
