Torch Height Controller (THC)

Torch Height Controller (THC) is an advanced automation device used in CNC plasma and flame cutting systems to maintain a constant distance between the cutting torch and the workpiece. It automatically adjusts torch height in real-time to ensure stable arc performance, improved cut quality, and reduced consumable wear.

Widely used in CNC plasma cutting machines, THC systems enhance cutting accuracy by compensating for uneven or warped metal surfaces during operation. This results in smoother cuts, reduced dross formation, and improved overall productivity in industrial cutting environments.
