Hi
I'm new to cnc plasma cutting, I received my new table a few months ago and have been just playing with different materials and thickneses. I have a real job now to cut, it's a bunch of .75 and 1.75 diameter holes in .375 hot roll plate. I'm getting about .025 to .035 of bevel from the top of the hole to the bottom, I don't know if this is as good as it gets or if I should be able to get better results with different settings. I have tried different THC settings,amps,cut direction, and cut speeds and can't seem to get it any better. My final settings using a Hypertherm 1250 are 137V THC, 80Amp,50 IPM. I would really appreciate any info on whether this is normal or suggestions on how to get it a little better.
Thanks for your time
Chris
