The CommandTHC is a microprocessor-based torch height control system which accurately sets the initial piercing height and controls the torch-to-work distance of a plasma torch during cutting operations.
Torch-to-work distance is crucial to maintain optimal cut quality. The CommandTHC works with X-Y cutting systems to control this critical parameter and maximize plasma cutting quality and productivity.

Superior height control |
Flexible operation |
| The system will respond to arc voltage
changes of less than 1 volt.
Maximum speed of retract exceeds 200
ipm(5.0 m/min).
Built-in Ohmic touch-retract initial height
sensing(IHS) feature ensures accurate,
repeatable initial piercing height settings.
A work-clear feature senses the loss of
Ohmic contact for accurate positioning,
even on thin, flexible sheet metal.
Built-in motor-stall IHS feature is always
active and serves as a back-up for the
Ohmic IHS, when cutting non-conductive
material surfaces, such as painted plate or
underwater cutting.
Rapid pull-back feature moves the torch
away from the workpiece if a touch is
detected during cutting.* This collision
avoidance feature will prevent crashes such
as workpieces that tip up or buckle.
CNC-controlled arc voltage control can be
disabled during cornering to keep the torch
from diving at corners.
Over-voltage protection automatically
eliminates "torch diving" during large, out-oflimits
arc voltage fluctuations; such as kerf
crossings or cutting off the edge of a plate.*
Built-in, advance preflow reduces cycle
time by allowing gas to preflow during the
IHS cycle.
Optional breakaway is designed to reduce
or eliminate damage to the torch due to
accidental collisions in all axis. Maximum reliability Heavy duty, 100% duty cycle. Built-in power-up diagnostics. Backed by Hypertherm warranty: two years on all control modules, one year on torch lifter station. |
An optional operator control pendant with backlit liquid crystal display allows easy system setup, operation and monitoring.
Distances can employ inch or metric units.
Programmable set points for cutting height via operator control pendant.
Programmable delays for pierce time, machine motion acceleration time and torch retract delay time.
All features and parameters can be set remotely via RS422 serial interface, for complete CNC control.
System designed to work with any AC line input voltages currently available worldwide.
System diagnostics can be displayed or transferred to the CNC.
Optimized X-Y torch lifter station Advanced-technology, high-torque motor allows 50-pound(25 kg) load capacity. 8 inches(203 mm) active stroke. 200 ipm(5 m/min) maximum z-axis travel speed. Positioning resolution 0.001 inch(0.025 mm). Moving mechanical parts are protected from the environment by a Teflon-coated, fiberglass sealing band and a mechanized shield. Moving parts are dry lubricated; no oil lubrication is required. Non-contact/inductive, upper and lower-limit switches. |
