Copper cutting/melting with Oxy/Acet
I have been trying to cut/melt figures out of 16oz. flashing using my oxy/acet welding torches. I also want to be able to lightly melt the edge of hand cut pieces. I have not had much success at this and have resorted to cutting pieces with aviation snips. I notice small pieces will melt quicker with lots of heat and larger pieces seem to disapate the heat fast. I have seen videos on websites where copper is easily cut with a torch. Can someone share with me the technique for successful oxy/gas cutting, melting and brazing copper.
