I have to say that it's been a quite a while since I burned a transformer primarily because of the safety issues. We still process medium to large transformers but we do it without flame these days. The more traditional methods are used by us but the one thing that definitely helps is simply spraying PB Blaster or dunking it in the solvent tank for a bit. What does this do? It helps loosen the wraps and wedges, they essentially fall right out after lightly tapping on them.



Transformers can have some very heavy amounts of wonderful copper depending upon what kind it is, obviously the best type are those that you cut a band and they come apart in halfs, those are fun to get. The next best would be the ones that are bolted together, take out the two or four little bolts and they too break in half.

At one point we tried an experiment that had good results but was not really cost effective, we used a creamatorium (For Lg. animals) it was primarily for burning the hard wraps & varnish coating off the CU.... and oh it worked.

Merry Christmas & Happy New Year to All!
