• Rapid Part technology minimizes cut-to-cut cycle time – for a dramatic increase in parts per hour.
• Automated Initial Height Sense (IHS) minimizes the time for the torch to find the plate without risking damage; IHS is automatically skipped where possible based on part geometry and plate characteristics.
• Rapid z-axis movement to an automatically set retract height minimizes torch retract time.

• Optimal consumable life and superior cut quality through arc voltage sampling and control
• Extremely robust mechanics ensure highest reliability, backed by a two-year warranty
• Hypernet installation simplifies operation and reduces installation time

• CNC Controller sends a start signal to the THC unit.
• The unit initiates its internal routine, which will find where the Material (plate to be cut) is (Called IHS: Initial height sensing) by loweing the torch until Ohmic Contact is established or Floating switch is triggered, then raises to pierce height. Also there is compensation for preset height for floating switch which will be added to the raising of torch. The lowering is done at a lower speed and raising is done at full speed.
• The THC sends Plasma Start signal to the Plasma unit to start the plasma arc after IHS is completed.
• The THC waits until "pierce delay" then returns to "cutting height", starts reading voltage from the Plasma Unit, Once a sufficient voltage is reached the THC Outputs ARC OK signal to the CNC Controller that it is set and ready for motion or job start. The THC can also take ARC OK feedback signal from the Plasma Power Supply (if available).
• The THC then continuously reads the DC voltage and compares it with the Arc voltage [set by user] then raises the torch if actual voltage is less than set voltage or lowers the torch if actual voltage is greater than set voltage accordingly until START signal is available from the CNC Controller. If the voltage gap is suddenly more than ARC VOLTAGE CONTROL LIMIT volts it performs nothing until normal voltage range is resumed (kerf crossing etc..)
• If the Corner signal is sent by Controller (or Enable signal withdrawn) the THC stops raising / lowering the torch for the particular time.
