I think when my current compressor dies, I'll get a 2-stage. Much quieter operation is my main goal, plus enough air volume to
run a sand blast cabinet.

The stitch welder attachment is just a half wave diode, so gives you a 60Hz AC ripple current with every other cycle filtered
out. Bascially lets you run a higher voltage for a stable arc but cuts the current in half for less heat. That coupled with
the very small rods that you need to use with the unit allows you to run an AC buzz box on thinner sheet metal. I recently sold
the one that I got with my arc welder after I got a MIG.
