sd455dan, interesting that you saw a difference in output on the higher voltage. I had 240 plug already in place and never tried it on 120. Maybe that is why I was so impressed with it first time out.
I know it will slice through 5/8' high carbon cutting edges with no problems if you don't try to go too fast. If I am not using a very good technique sometimes I will get a lot of slag or closeups behind my cut, but that is on me, not the machine.
Sounds like there are a lot of good machines out there at reasonable prices these days. I was reluctant to give up the oxy/acet setup but not as reluctant as paying for gas and bottle rental prices, not to mention I always seemed to run out in the middle of a project on a weekend when the welding store was closed. Plus it was a 30 mile round trip to go fetch new bottles.
A plasma cutter was one of the best investments in my shop next to a big air compressor and a lathe.
