The set up I made for processing transformers is an Angle grinder used to dig into the weld. follow that up with an air hammer to knock the sides off. then depending on how its made you might be able to use the air hammer or manual swung hammer to slide the copper off or you may have to cut the copper and then slide it off. but pay close attention to if there is a weld or not. some are made where each layer is reversed sorta like a tongue and grove I guess. those ones are a pain to get apart. also unless your air hammer is the size they use on the highway the air hammer alone will not be enough to break the weld. and a vice really does help.
