AC welding for repairs

Jody,
You have mentioned using AC with Aluminum Bronze Rod for various situations.
If I'm welding cast iron with Al.Br. rod, what tungsten do I use since I'm trying to do it AC?
If I am welding a funky unknown bronze alloy casting and I want to try Aluminum Bronze rod on AC, what tungsten do I use and how do I prep it?
I'm typically set up with 2% thoriated, sharpened to a point. I don't know jack about AC adjustments.
---------------------------------------------------
I prefer 2% lanthanated but
2% thoriated will work fine.
taper at first not quite a sharp as you would on steel and it will ball on its own.
if you have an ac balance knob, set it to more penetration....and use a gas lens
