WARNING
the tHC lifter can injure your hand
the down-force pressure of the lifter can cause injury. be sure that the system is in a safe condition
before accessing the lifter area.
Manual mode
The ArcGlide THC can be operated in manual mode for special circumstances. In manual mode, there is no THC motion
unless it is initiated by the manual Up/Down switch on the HMI or CNC. Manual motion occurs in three stages:
1. Each time the switch is moved, the THC moves the torch 0.254 mm (0.010 in).
2. If the switch is held in one direction for more than 1/2 second, the torch begins to move continuously at the
programmed IHS Speed.
3. After 1 second, the torch accelerates to the programmed Slow Speed.
Manual mode is used to:
• Cut a flat workpiece when cut quality is not a primary concern. The torch cuts at the same height regardless of
consumable wear.
• Make rip cuts
• Mark on a flat workpiece
• Check arc voltage calibration
• Accommodate special conditions that do not operate well in automatic modes
Automatic modes
The ArcGlide THC is normally operated in one of the following three automatic modes:
• Arc voltage control (AVC) disabled
• Set arc voltage
• Sampled arc voltage
Automatic modes are most commonly used in production cutting applications. These modes use the settings from the
software and part programs in the CNC to govern the height, speed, timing, position, and movement of the torch.
