Steel rods are welding territory and you need intense focused heat like arc or OA. I'm a little curiouos about the Benzo Oxy rig. There seems to be more than one thing wrong with it, but people complain mostly about the O2 cost since the little O2 bottles run out pretty instantly. On the other hand, A real rig costs between 800-1000 dollars. I'm looking at 300 for the bottles, and in this case rental probably isn't an option, 100+ to fill them, 400 for the torch and accessories I want. So for a few frames I could buy a lot of O2 bottles. Anyway, I have TIG, and I can do the rest with propane.
