The “THC” stands for Torch Height Control: a module (hardware+ software) that automatically adjusts the Z-axis of a plasma cutting torch based on feedback from the plasma arc .
Improved cut quality: By keeping the torch at an optimal height relative to the material, the cut kerf, dross formation, and edge quality are improved. The Radonix documentation emphasises consistent, precise cutting performance.
Increased consumable life: If the torch sits too far or too close, consumables (nozzle, electrode) wear faster or get damaged. THC helps avoid that.
Automatic compensation for warping or uneven materials: Especially in heavy sheet metal or large plates, or surfaces that heat up and distort, THC allows the system to adapt in real time.
Reduced operator dependency / less manual intervention: Instead of frequent manual re-adjustments of torch height, the system automates it, freeing up resources and reducing human error.
Better process stability and reliability: Especially in production environments, consistent arc length means fewer rejects and less variation.
