I just graduated the Welding Trades course at are community college in Kalamazoo, Mich., and also aquired my (2) certifications in Mig/Tig. We used different makes and models of welders, but the one I enjoyed most (and easy to use) was the Miller Dynasty for Tig. Im applying my skills to building/designing tricked out bicycles that are of "retro" nature. Im insearch of a Miller Welder now, to get my career in bicycle building going. By the way. I passed my cert. test(s) with the Miller Dynasty. Thanks Miller!
