OK, I would agree with that on the surface. But bear with me a minute
and point out the folly of my logic. Say I put a 30 amp breaker in
there to handle the initial spike. The point of this entire
exercise is to have the DC running as little as possible and only as
needed. So, that being said, how dangerous is it if I have the 30 in
there, fire up the TS and DC for all of maybe 3 min at a time at the
absolute max, probably less, and that's it. I do this as a hobby, not
production, so my typical style is to turn on the TS, make 1 or 2
cuts, and turn it off. Is there something I'm missing?


Why not compromise and replace the breaker with the "slo-blo" variety? They
are built to accept temporary surges without going all crazy. One variety is
"High Magnetic Circuit Breaker" which will withstand temporary loads of up
to 20x its rated capacity. Here's one:
