If not, what would be advantages/disadvantages of the inverter compared to the MOSFET/IGBT machines?

These small answers are much more educational for me than trying to read the literature that I walk away from scratching my head.
Inverter technology by definition means taking a DC input and creating and AC output, which is what is happening after the wall AC V is rectified. This technology can use MOSFET's, BJT's, IGBT's, and/or a few other semiconductor device types.

I believe Everlast only makes inverter type boxes, but Mark, Mike, Ray, Duncan, Oleg, etc... would know for sure.
