I have no experience welding but figured I would give it a shot. I'd like to run a few beads to fill some gaps and seal some leaks. I'm also going to use angle bar to put "rails" in the CC for diffusion plates and a baffle. Since the CC is a thin oil drum and the angle bar is much heavier how can I go about doing this without burning holes in the drum? I'll be using a MIG welder since it seems to be the easiest for a newbie. TIA
