The problem will more be burning out the converter, I think. If it's on
an appropriately sized breaker or it has thermal overloads (heaters),
then you should be ok if the saw does try to draw excessive power. If
it (the converter) isn't protected, let it run on no load (assuming it
starts) for a while and do a sanity temperature check.
