As many of you already already know, I'm only 16, but i'm starting my second project this summer, Project Charlie Daniels. I'm going to be doing a lot of welding with my friends, and have a couple experienced friends willing to teach me (one w/ 8 years experience, one with 45 years experience) but they aren't in town now. This project will be a ground up project starting with nothing more than some I beams and a large chop saw. To connect the beams I've been planning on welding plate steel to the end and bolting it together. I need STRONG welds, not necessarily pretty. What kind of welder should I look for. I'll be searching for old welders, maybe eBay, maybe classifieds, who knows, but what kind of welder would be optimum? Gas? Wire? MIG? Arc? Stick? TIG? Thanks for the help.
