Anyone have proma thc with his hypertherm machine ? i have powermax 85 and I use the cpc port signal (50/1) to go to thc. When i start cutting , My torch goes too high , about 1/2 inch from the material . The material is 3/16 mild steel , so I set my speed to 75 ipm, thc at 135v, 45 amps ( hypertherm speed chart). I read 3.2v from cpc port .. I set the hysteresis at 4 on proma . Thanks in advance

Where do you get your 135v from??
If it is from "the book" forget it - do some straight line cut tests with z up/down turned off and note the voltage which gives you the correct height, this is then your voltage for that material at that speed and at that current.
