I was steeling myself to swapping them out, but instead I walked in the office, sat down at my desk, found a unit capable of drying 75CFM and
handles much higher pressure, and ordered it.

I was about ready to go ahead and swap in my spare unit when I got an
email notification the new 75CFM dryer will be arriving tomorrow.

I wonder if it would be worth my while to plumb in the backup unit
inside the machine room for redundancy? It would only be drying already
dried air anyway.

Or I could make a rolling service cart for my plasma cutter and put it
on the bottom of the cart with the baby plasma on top.

I rarely use the plasma cutter. I usually use one of the OA torches
instead. I usually only use the plasma on aluminum when I saw won't do.

You could plumb it in with disconnect fittings such as unions and flex
hose and make a straight pipe replacement from the piece cut out to
quickly swap in if you need the dryer elsewhere. I did that with a
tempering tank in the water heater's feed line and swapped when a weld
on the tank began to leak.

It's a Monel (copper+nickel) electric water heater tank with mild steel
angle welded on as supports, contamination which apparently saved it
from recycling at the scrapyard. Some day I may grind or etch out the
rusty steel and TIG the holes with nickel or Nickels.

Would Invar 42 work ? I could spare a couple or 3 sticks .

It might but this is a waste of it. Expensive welding and brazing rods
are among my most valuable flea market treasure finds.

Maybe you could use some cunifer brake tube a filler material, normally available in small quantities and not too expensive IME.
