I have skipped around Google, now to ask the experts.
To make use of salvaged microwave transformers, how can one stop or lessen
the heating effect of the core. I have cut out the secondary winding and
the magnetron heater windings as well as remove the magnetic shunts. I have
even added about 4 turns to the primary (#14 gauge copper). Still with no
load on secondary (with is #12 copper after rewind), it still gets warm to
the touch. Would I need to also cut out the welds on the core to lessen the
eddy currents?
I wound the secondary till I get 20 volts out with a load of 1 amp, 21.8
with no load.
Anyway, what else might I try to calm the eddies so it runs cooler?
