Sounds like the repeated heating is doing 90% of the work here. Heat is
usually the last resort anyway, since one always worries about heating
delicate parts nearby.
One thing I *have* done, and it works quite well, is weld a big nut to a
rounded bolt head or broken stub (or a combination of a fender washer
and big nut). Granted, the heat and current of welding is helping, but
it also makes a nice big "thing" to put a wrench on.
The one thing that "never" works are ez-outs!
