Sure the boiler is cast? All I've ever seen have been riveted iron or
steel sheet, for which a plasma cutter(or cutting torch) would be
ideal. A 10 lb sledge works wonders on cast fittings and radiators,
though(bathtubs, too). Not sure why a cutting torch would be less
safe than a plasma cutter, you've still got very hot particles flying
around, the fire hazard is going to be about the same. You're going
to have to have a hefty power supply for a plasma cutter, plus air or
a gas bottle. May have to have a generator if the house supply won't
support it.
