Razorcut 80 - CNC port wiring

LS-THC (Torch Height Control) Plasma Cutter Wiring (Raw and Divided)
1

Hi,

I have a Razorcut 80, but I am not sure how to connect it and do not want to get it wrong!

Here is the pin out for the plug

RAZOR CUT 45/80 CNC 14 PIN SOCKET PINOUTS
PIN
3 START
4 START
5 VDIV-
6 VDIV+
12 TRANSFER
13 GND
14 TRANSFER

I have to change a jumper in the plasma to give me 50:1 output

Then connect to pin 5 and 6 to the Divided Voltage Input Pigtail Cable and plug in to the DIV INPUT of the THC. does this matter which polarity?

Pins 3 & 4 go to the torch firing cable plug that into the TORCH ON/OFF jack

But what about 12,13 &14?

Welcome,

Yes it will matter for the THC there is a + and a -.
Yes 3 and 4 would be for the trigger.
The rest are not used.

and as per the guide it is black to the positive pin 6 and red to the negative pin 5?

Some times, its always good to test all wires before you hook them up.
