I'm looking at taking a welding class or two at my local community college and was wondering what type of welding would give me the most bang for my buck? Something that will serve me well in building/modifying motorcycles (seat hoop, rearsets, etc.,) Mig, Tig, Arc, Oxy.? I think for the fall semester I only have one option available; Oxy. I guess my real question is, would Oxy. allow me to do a lot on frames and such?
