Then clean the cardboard insulation off the coils to get 'Copper #2' price for it.
That's pretty much what i do. Angle grinder with a cut off disc to score the welds, hammer out the E, and clean the crap off the copper with a wire wheel on the angle grinder.

Angle grinder + cut off discs. It's one of the best tools a scrapper can have.
