THC Divider Board: 1:50 Arc Voltage Divider for Plasma THC
$40.00
Arc voltage divider board for CNC plasma torch height control: integrated 1:50 divider with noise filtering delivers a clean, safe signal to the THC3T-02. For plasma cutters without a built-in divided arc voltage output; Mach3 systems. Made in Vietnam by Robot3T.
The THC Divider Board lets a torch height controller read the arc voltage of your plasma cutter safely and accurately. It divides the high arc voltage by 50 and filters out electrical noise, delivering a clean, low-voltage signal that the THC3T-02 can use to keep the torch at the right height. It is the simple solution for plasma sources that have no built-in divided arc voltage output, and it is designed for systems running Mach3. Designed and built by Robot3T in Vietnam.

- No divided arc voltage output: your plasma cutter does not provide a ready-made, scaled arc voltage signal.
- Noisy readings: unstable torch height caused by interference from the plasma arc.
- New THC installations: adding THC3T-02 height control to a CNC plasma machine.
Why use the divider board
- Safe – brings the high arc voltage down to a safe signal level for the controller.
- Accurate – fixed 1:50 ratio for a precise, repeatable height reference.
- Clean signal – noise filtering improves THC stability and cut quality.
- Matched to THC3T-02 – works with both Up/Down and Step/Dir versions.

Frequently asked questions
Does my plasma cutter need a divider board?
If it already has a divided (scaled) arc voltage output, you may not need one. Tell us your plasma model and we will confirm.
Can I buy it together with the THC3T-02?
Yes. We recommend ordering them together so the set is tested and ready to install.
Is installation safe?
The board connects to high arc voltage. Installation should be done by a qualified technician with the plasma cutter switched off, following our wiring guide.
Do you ship outside Vietnam?
Yes. Contact sales@robot3t.com for a quote including shipping to your country.
Setting up torch height control?
Tell us your plasma source and CNC software. Our engineers will recommend the right THC and divider set, and quote at no cost.
