VHC-200 arc pressure height controller is suitable for plasma below 100A without high frequency ignition. Basic functions include arc pressure setting, initial positioning, automatic cutting operation, automatic height control, and arc success output.
The Mycut VHC-200 arc‑height controller provides automatic height control for plasma torches on CNC cutting machines. It supports two positioning methods—protective‑cap contact and proximity‑switch detection—and can operate with plasma cutters up to 100 A without high‑frequency ignition.
The manual details installation, wiring, initial positioning, parameter settings, and troubleshooting. It includes technical specifications, interface pin assignments, and a parts list for the standard factory configuration. This manual is written in Chinese.
| Working voltage | AC24V±10% 50/60Hz |
|---|---|
| Drive motor | DC24V permanent‑magnet DC motor |
| Drive method | Relay output |
| Output power | 20 W |
| Operating temperature | -10 °C to 60 °C |
| Control accuracy | ±3~5 V |
| Initial positioning methods | Protective‑cap contact / Proximity‑switch |
The controller can use either protective‑cap contact positioning or proximity‑switch positioning to detect the torch height.
Adjust the potentiometer RP2 clockwise to raise the height or counter‑clockwise to lower it.
An AC24V supply with a tolerance of ±10% is required.
