Cut chart for a Hypertherm Powermax 1000 G3

[Ewalk02]

Does anyone have a cut chart or SheetCam toolset for a powermax 1000 g3? I have the basic chart that comes with the machine but if anyone can clue me in on kerf widths, pierce delays, pierce heights, and plunge rates I'd sure be greatful!

Thanks!

I do not believe that there is any guidance on plunge rates.... as quick (fast) as possible after pierce delay has been the only guidance I have seen.... but everyone uses a different number. if someone has an accredited post it would be appreciated (accredited = Jim colt / a hypertherm pdf)

I'm not completely sure what "plunge rate" is...but I suspect it is the z axis (height control axis) speed. Hypertherm plasma systems are installed on many different machine designs....the z axis speed should be set according to the design of the z axis and its acceleration and deacceleration characteristics. If the z is too fast it will overshoot when trying to get to the correct arc voltage....and the result will be oscillation....which will roughen the cut edge. Some z axis speeds are set at 30 to 40 ipm, others at 400 ipm...I suggest setting it to the maximum setting that ensures smooth motion with no oscilation. The ideal goal is to maintain very accurate torch to work distance throughout the cut to compensate for warpage, out of level, as well as thermally induced plate movement conditions.

Makes sense on the plunge rate, thanks for the help. I'm still not seeing a whole lot on kerf widths but I think I'll just run with what people are using for the 45X as a starting point. I got a great deal on an older power supply (1000 G3) but it still has the old discontinued torch and different consumables than newer machines. Guess I'll end up doing a good amount of trial and error. Thanks again.
