Do you use it straight or do I need to add water/something else?
I don't burn wire. Either strip it or it goes as insulated.
I do have some burned however, from a fire salvage. Local fire dept burned 2 homes and I got all the scrap. Now I gotta clean it. Yard has no problems with the burned tin, but I see them having a problem with the wire.
Pics if any one wants to see.
