Automatic plasma Z-axis control
Radonix Torch Height Controller
The Radonix Torch Height Controller (THC) combines hardware and software to adjust the Z-axis of a plasma cutting torch using plasma-arc voltage feedback. It maintains a more consistent torch-to-material distance as plate height, heat distortion and surface conditions change.

Core capabilities
Control, connectivity and integration
Compare motion, I/O and integration capabilities for machine design and controller selection.
Arc-Voltage Feedback
The module monitors plasma-arc voltage and adjusts the Z axis as arc length changes.
Radonix Integration
Designed as part of the Radonix controller and interface stack for plasma cutting systems.
Configurable Software Parameters
Parameters include sensitivity, initial touch height, contact and arc sensing, pierce delay, TorchValue, THCGain, AlwaysTouch, CutDistance and TouchVelocity.
Improved Cut Quality
Maintaining the intended torch height helps improve kerf consistency, dross control and edge quality.
Consumable Protection
Avoiding excessive or insufficient torch distance can reduce unnecessary nozzle and electrode wear.
Automatic Surface Compensation
Real-time adjustment helps compensate for warped, uneven or heat-distorted plate.
