Hi
Finally received my new plasma/router table and I have a few questions regarding cut quality. Below I have listed
material and what settings I'm using.
16 ga hot roll steel
Hypertherm 1250
fine cut consumables
40 amp
100v THC (tip approx. 1/16-3/32 off work)
150 IPM (linear guide rails, belt reduction stepper motors)
What kind of kerf width should I expect to see with 16 ga? Right now with this set up I have, it is around .035-.040 wide, seems kind of fat but I really have no idea what to expect. I was trying to cut some 2 inch stars and some letter E's and corners were really round loosing the detail, I think because the kerf is so wide.
On the back of the piece after cutting I have a bead around the whole thing, it looks like a small weld bead from a TIG weld. Is this normal on 16 ga.? I know Iv'e seen some slag left, but that just chips off easily but this is more of a bead that would all have to be ground off.
Any info on these subjects would be greatly appreciated, sorry if these are dumb questions but this is my first attempt at CNC plasma so bear with me for a few years.
Thanks for your time.
