If you are really into learning more about welding, there is a great forum with some very seasoned experts at weldingweb.com.
Get argon/c02 and your whole welding experience will change. You may end up like me sharing my love for the old trucks with making innovative and elaborate jigs to make the restorations easier. I don't get much done, but I am happy with what I can do. The weldingweb forum really unlocked that capability. The guys here are the best.. hang out here for sure, but when its time to make welding tables, jigs, etc... thereyago!
