I need to cut some iron castings. What can I do, perhaps with a special
welding rod or 6010?

You should be able to make a simple oxygen lance in your shop.
A diy arc air rig will also work. Both are fast and easy to make.
Incase the material is oily or greasy have a couple of co2
extingquishers near by and a helper watch out for any fires
that may erupt.

Best Regards
Tom.
