I don't mind doing the calculations, but I have a monster air compressor
and air reserve and it would take forever for it to kick in. I'll see
about making a small tank or something to do a measurement.
I still need to find out how to dial in the air. 50-70PSI and it doesn't
seem to make a difference in the cuts.

I could certainly be mistaken; maybe it does use only 3.5 scfm. But I
sure
wouldn't want to bet $500 on it. Manufacturers are usually good at
presenting their products in the best possible light, and being able to
run
with a small (portable) compressor would certainly be an advantage for a
unit with a handle on the top.
Maybe Moose can give us a measurement. Start cutting with a full tank of
air and count seconds before the compressor kicks in. If you know the
cut-in and cut-out pressures, plus the tank capacity, you can calculate
roughly how many scfm you were drawing.
