Re: powermax 1000 torch..... (jimcolt )

No, it is not compatible with the Powermax1000. The wiring connectors and air fittings are different. You can get the same torch (Duramax) that is used as a retrofit torch that will plug into the Powermax connectors. You can find it on the the Hypertherm website. Jim Colt Hypertherm

Re: Using finecuts without increased pierce heightt

You can get away with .060" cut and pierce height if you stay under 16 gauge and use a bit of pierce delay (to allow the pierce to penetrate before motion starts). Use the roller ball plate rider that is on the Cybermation to maintain the height. Jim Colt Hypertherm

Re: Tips or tricks to using Finecut consumables?

I only recommend Finecuts at a higher cut height (and higher voltage to maintain that cut height) when cutting 14, 12 and 10 gauge. On thinner materials you should stick with the book height of .06" for best results. When the height is correct...the book speeds will provide best cut quality, sl...

Re: 3/16 vs fine cut

The Hypertherm website does not (to the best of my knowledge) say that the Powermax45 Xp can cut 3/16" with Finecut consumables. The Finecuts are recommended for a maximum of 10 gauge...or roughly 1/8" maximum thickness. You can cut thicker, however there are no specs for cut speed, pierce...

Re: DROSS. SHEET PRE-TREATMENT AND POST CLEANUP.

Best bet is to cut with virtually no dross. Depending on what cnc machine, height control and plasma...you may or may not be able to do this.

Re: My New Hypertherm 45 XP

Well....had you contacted me I would have suggested on 14 gauge that you should not slow down the cut speed (if it was not penetrating 14 gauge) rather, you should increase the cut height setting from .06" to .08" and also increase the arc voltage so that the cut height during steady state...

Re: Overcut issue or ????

The lag lines indicate that your cut speed might be too fast....though it could also be height slightly too high. 1/2" cuts at the right speed and height should drop, even if done at 45 Amps. Overall they look good. Thicker is generally easier to dial in cut quality than gauge material. For DJR...

Re: Inches per min vs amp. Volts?

Generally you only need to change the book cut height of .06" to a higher height (.075" to .080") when cutting thcker materials with Finecut, like 14, 12 and 10 gauge. This is likely due to chemistry of the plate, such as high silicon, high manganese or high carbon content. The sysmpt...

Re: stainless 10ga hypertherm 85

Books settings on stainless seem to always work for me. Make sure your cut height is correct. If you set .06", measure to see if it really is. If you have a height control where you set a voltage to control height....be sure the voltage you set gets you the correct physical height (measure it)....

To read that the voltage is correct you need to do a test like this: 1. Set up torch for a cut at a fixed speed and fixed cut height in a straight line. 2. Connect a meter to read raw arc voltage directly off the + and - terminals on the Main Power Board. Write the voltage down while cutting the abo...
