Torch Height Controller | PROMA THC SD | For CNC Plasma Cutting Machine

The PROMA THC (Torch Height Controller) 150 controller is a widely used plasma torch height controller equipped with Up/Down relay outputs and an ARC OK signal to confirm arc ignition. It is compatible with CNC control systems that support THC up/down signals, such as MACH 3, LinuxCNC, and CNConv. Its integration with a voltage divider makes the connection process straightforward.

This unit is a modern, microprocessor-based analogue plasma torch height controller. It functions by analyzing voltage changes in the plasma source, which occur due to variations in the height between the torch tip and the material being cut.
