So there's no need for a voltage divider with the PowerMax 45xp ?

Hello. Thank you for making this video. I found it to be very useful. I am especially impressed with the 3D model of the wiring and comports near time mark 3:00. Is the software used to do a 3D model of cabinet and wiring also available?

Hi there, I'm using an older model Hypertherm powermax 1000 G3 series power pack and I'm a bit confused about how and where to connect an arc good signal. Thanks

So if my manual says "Arc Voltage Output" 1:1 ratio then that would mean It needs to be hooked up as ARC RAW?

BTW I have a "Lotos Supreme LTP5500DCNC" Plasma Cutter

I forgot to connect the materialclamp😣The system doesnt read the arc voltage anymore even if I reconnect the clamp. Is the interface broken because of that?
