Working backwards which is a highly refined skill of mine... Let me look at your first questions now,
Corten is very formable while cold and responds well to cold hammering or breaking (bending) in a press. Corten feels a little softer than hot rolled mild steel when hand forming.
Corten will not heat harden at all so you can weld on it until your out of stainless wire and be just fine.
I'm still pretty sure I used an argon cover gas for my welding of the stainless and corten.
Yes I read the date of your original post on this topic, the work has probably been long finished by now.
