ArcGlide THC Instruction Manual 1-3
SPECIFICATIONS
Introduction
The Hypertherm ArcGlide THC is a voltage sensing, torch height control (THC) system that is designed for plasma
cutting applications on an X-Y cutting table. The system uses the plasma arc voltage to control the physical distance
between the torch and the workpiece during cutting. Up to 4 ArcGlide systems can be installed on a cutting table. The
system includes the following components, as shown in the illustration on the facing page:
Control module
The control module houses a microcontroller, I/O interface, and a motor drive. This unit provides arc voltage control,
and interfaces with the torch lifter, the CNC machine, and the plasma system through standard discrete I/O interfaces
through the Hypernet
®
interface.
Lifter assembly
The torch lifter station, under control of the control module, positions a torch head vertically above the workpiece.
The lifter has the following features:
• Ability to detect the workpiece using Ohmic contact sense circuitry or stall force
• Magnetic torch breakaway with circuitry to indicate a collision
• Lifter station enable and disable switch with an indicator light
• Manual up and down switch
• Laser pointer for work piece alignment
• Single interface cable
Human machine interface (HMI)
The HMI includes a liquid crystal display (LCD), operating switches, and a rotary/push knob selector for THC setup and
control. This module is optional when used with Hypertherm CNCs that can run Phoenix version 9.5 software (or later).
The main functions are:
• THC system and operational setup
• Entry for operating parameters
• Manual and automatic operation
• Initial height sense (IHS) test
• THC status and arc voltage display
• THC error display
• Multiple language support
• English or metric unit support
• Station enable and disable
