I don't have a photo, but the scrap yard would only give us Copper #2 for some copper bars we had from an old welding machine.
They said it's "machine copper" , definitely not #1. Any ideas what type of copper was used on old commercial welding machines that were built with copper and brass?
We had a few bare chunks of copper, about 25lbs each..
For the brass they identified it as C-Metal brass which was the top paid.
