I was wondering what rod you guys use for gas welding on sheetmetal. I have been using some Radnor ER70S2 1/16" rod, and hammering it after I weld it. It seems like it is hard when I hammer and dollie it, and I would like something more malleable. The local welding supply has been of very little help. I did try (maybe I shouldn't say this) using bailing wire, and it actually works pretty well. Lower melting point and super easy to work after its welded. So what do you use?
