This document provides the user manual for the XPTHC-III Simple Arc Voltage Height Controller from HYD CNC Technology CO.,LTD. The controller is used for automatic control of the cutting torch height in plasma cutting machines. It features a compact size, complete functionality, easy operation, simple wiring, and stable performance.
The XPTHC-III is a compact arc‑pressure height controller designed for plasma cutting machines. It automatically controls torch lift and descent by monitoring the plasma arc voltage, enabling precise height regulation during cutting.
The controller can drive a DC24 V motor or a stepper motor (1 kHz pulse), offers two initial positioning methods (switch‑type and protective‑cap contact), and includes isolation voltage‑divider circuitry (100:1) for safe signal handling. Wiring diagrams, signal definitions, and installation tips are provided throughout the manual. This manual is written in Chinese.
| Working voltage (AC) | AC220V ±5%, 50/60 Hz |

| Output current | 1 A |
| Output power (DC motor) | 20 W |
| Operating temperature | -10 °C to 60 °C |
| Initial positioning methods | Switch‑type and protective‑cap contact (both usable) |

It monitors changes in the plasma arc voltage via an isolation voltage‑divider to determine the torch height during cutting.
The controller supports both a switch‑type initial positioning and a protective‑cap contact method, and they can be used simultaneously.
It can drive a DC24 V motor directly or a stepper motor with a 1 kHz pulse frequency.
