Sparky, thanks for the response.

I'll call the utility and specifically ask about the welder. They're know about the upgrade (which shouldn't have to be mentioned, but probably does), but we haven't mentioned specific loads.

I was planning on using a GE TM4020RCU (PowerMark Gold load center.) The breaker is a GE TQDL21125. The only limitation I could find is a note in the GE literature that its use requires four one-inch spaces (the breaker itself fills two spaces.)

Incoming power is a standard single family residential setup, all secondary service. The utility supplies a 225A socket. Except for the shop loads, it's a pretty straightforward setup; I'm not sure what else to mention about it.
