According to Willie, there’s “not a better buddy to show up to your house on a weekend and say, ‘Hey, you wanna do some welding?!’” than the Wizard of Welding himself, Bob Bitzky. Trainer, teacher, professor, product developer; you name it, Bob’s done it. Today he joins the guys to lay down some serious knowledge about welding in general and TIG, chromoly, and aluminum in particular. “If you’re a steel welder and I’m gonna take you over to the aluminum side,” he notes, “I may have to remove your brain and turn it around inside your head.”
