wrought iron fence repair: wire and settings needed.

[johnnymg]

Big Greetings

I'm going to be repairing an old wrought iron fence and would like some recommendations on what process/materials to use. I'll likely use my imig 200 so settings/wire recs for OUTDOOR welding is what I'm looking for. I have a bunch of ER70S wire (in the usual suspect sizes) but I'm thinking that maybe a dual shield wire would be better for outdoor welding. ????

FWIW, the square tubing I'm repairing into is somewhat "worn". i.e. a bit rusty inside. This is mostly a cosmetic repair for now.

thanks a bunch!
