Tip voltage setting recomendations?

[Orangejbird]

What would be a good starting point for say a Cutmaster 52 with a 30amp tip cutting 20 gauge mild steel.

Anyone know of a chart ?

Want to have it set close for ATHC to work well.
How about IPM recommendation?

Anyone know a good rule of thumb for settings?
I ruined a 60 amp tip on one cutout and I'm sure I didn't have the right tip voltage setting for my tip OR material because the torch didn't seem to keep proper distance from metal. Any help?

bueller, anyone?

program to cut a 10"+ line at rec. speed set torch rec. height off steel thc off and cut, watch tip volts. This will give a baseline.

My hypertherm 1000: 60 amp machine
40a tip 148 volts 22G steel 325 ipm
fine cut 40a tip 78 volts 20G steel 120 ipm

I use a 20 Amp drag tip with a 20 Amp setting. Drag the tip right on the metal for thin gauge stock. Works for me.

Up to what thickness? 1/16"? What IPM for 20amp on different gauges?

Go on the therm. site lookup your cutter go into the manual and print out all the settings. I looked they're there.
