Do you break down copper transformers?

This is from another thread, but it is how I bust the "E" transformers. https://www.scrapmetalforum.com/gene...rs-copper.html

Give the weld a few good whacks with the hatchet
The weld will break and you can knock off the metal, giving you easy access to the windings

It is really easy!

I may give the "8" transformers a try with an angle grinder just to see how it shakes out.

I push the copper or laminated steel out with a 12 ton Harbor Freight press.
