It can automaticly adjust the height between the sheet metal to the plasma torch.
Morely used in the portable cnc plasma cutting machine, Mini sheet metal plasma cutter.
CHC-200F work elements: It detects the distance between Sensor ring and the cutting material (steel, metal material) via detecting the capacitance between the two parts, and keep the two parts at a set distance by control the DC motor move. CHC-200F is a closed-loop control system, with 4 parts: Position Signal Sensing, Signal Process, Logic Control and Motor Drive.
