If you plan to just weld as a hobby then classes are not needed. Get you a nice (preferably Miller, Lincoln is second choice IMO) MIG welder and then just practice. You will learn to KNOW in your head the setting that you need to a certain size metal, etc. Practice before you do a frame or such by getting TWO of the EXACT same sizes of metal that the frame or whatever you are welding will be and do a test bead.... Get your setting right and look on the back of the metal. If it is penetrating well then there you go. Like whoever above said, MIG is easy, just takes a little time to get it down and lay REAL nice beads. Now TIG is another thing.
Thanks for the links though, I will definetely check them out. Oh and I decided to change my major from auto body to Welding and Fabrication and taking night classes here at my community college and getting a diploma from it. Should be fun! "D Good luck Pat and keep us updated on your welding skills and what kind of welder you get!
