I have posted this one up before, but here is some 3/16" cut at (if I remember right) about 45 IPM at 40 amps.
The second picture is a comparison of a 3/16 part cut with a laser(bottom part), a 3/16 part cut with a 40 amp TD plasma (middle part), and a 1/4 part cut with oxyfuel. All 3 parts were wire wheeled to give cut edge clarity. No real slag to speak of.
EDIT: These were not cut on a Torchmate table, but on a home made machine. A professionally built table might give even better results.
