If arc voltage is higher than Ref HYS2 then down signal is generated.

This article will guide you through the process of setting THC with your CNC controller board and Mach3.

H3 Cnc Tutorial 32 Bit Microprocessors Voltage

PlasmaSens and PlasmaSensOut are design on modern 32 bit microprocessors voltage measurement technology.

High voltage input up to 350 VDC or low voltage input up to 10 VDC.

The last one is suitable for cutters with internal voltage divider output.

However, PlasmaSens comes with optical interface and is meant to be used with CNC controller board PK57CNC.

While on the other hand PlasmaSensOut comes with the user friendly HMI device and can be connected with any other CNC controller board.

PlasmaSensOut namely generates universal THC control signals ArcOK, TorchUp and TorchDown.

Description for PlasmaSensOut can be used to setup any other generic CNC controller board.

H3 Cnc Tutorial How To Start With

I also advise you to browse on a YouTube how to start with Mach3.

The PoKeys Mach3 plugin will be automatically installed along with the app.

To be sure, you can check if PoKeys.dll exists in C:Mach3PlugIns folder.

It is always a good idea to install the latest application and plugin version.

Connect AC power supply (110 VAC-230 VAC50-60 Hz) and apply optical cable to PlasmaSens and optical interface.

Make sure you remove plastic caps at optical transmitterreceiver and protection caps on the optical cable.

In that case you will probably need to do some adaptation on the cutter itself as usually doesnt have such an output.

Make sure you use a double isolated short wire for voltage detection.

Watch for polarity A cutters clamp is positive voltage potential and it goes to pin1.

However you must first select Voltageanalog mode to be able change Torch voltage input and then switch back to PlasmaSens.

But in this case we connect the optical cable to the HMI device.

PlasmaSensOut has three standard THC output signals (ArcOK, Up and Down).

The LED display will start flashing then the setup menu will appear.

Select the parameter you would like to change by pressing V button and confirm with button.
