Arc Voltage and Capacitive Height Control

Torch height controllers use different feedback methods. An arc voltage controller uses a plasma cutting arc as a feedback signal; a capacitive controller uses a sensor to detect the workpiece. The controller, sensor, torch, power source and lifter must be considered as a system.

Check the specific application

The CHC-200F product information identifies flame cutting as an application. For plasma cutting, it specifies operation above water at currents below 100 A with a non-high-frequency start. It explicitly prohibits use with a high-frequency-start plasma power supply. These conditions apply to the CHC-200F; check the documentation for the exact model and configuration when selecting another controller.

Before selecting or installing a controller, confirm the cutting process, power source and starting method, sensor arrangement, lifter motor, interfaces and operating conditions against the applicable equipment manuals. Installation and commissioning must follow the equipment manufacturers’ instructions and applicable electrical safety requirements.
