Key features as follow,

A, Auto Initial Height Sensing(IHS)

Torch Retaining Cap IHS and Proximity Switch IHS (NPN and PNP), Proximity Switch IHS is backup for Torch Retaining Cap IHS for cutting dirty/rusty workpiece, needing the Anti-Collision Fixture designed by HYD (breakaway kit ).

B, Anti-Collision Function

No matter THC is on Auto mode or Manual mode, when torch head touches the workpiece, THC automatically lift torch up to IHS height. So with XPTHC-300, user no need to worry about torch head crashing.

C, Freeze Auto Height Control on Corner Signal

XPTHC-300 would freeze Auto Mode on receiving corner signal from CNC system to avoid torch diving, and we have a unique design to backup this function. We set 30V (adjustable) as Turning Point according to our years practice. When the Actual Arc Voltage is higher than Set Arc Voltage over 30V, THC Auto Control Mode freezes to avoid torch head diving, until it goes back to 30V range. This Over Voltage protection can avoid torch diving on voltage spikes

D. Set Pierce Time

Set the Button (Set PIERCE) to set Pierce Time. XPTHC-300 support Dynamic pierce on cutting thick material.

History of HYD Torch height controller

1996made first capacitive torch height controller (Analog circuit);

1998made first arc voltage torch height controller (Analog circuit);

2003designed SCM based PTHC (Ontime);

2004set up HYD.CNC Tech Co, stopped developing of immature Ontime THC, and returned to Analog Circuit design, developed XPTHC-100 and CHC-200D, and simplified XPTHC-II

2006made XPTHC-100II, CHC-200DII, and XPTHC-III;

2008made capacitive CHC-300 for laser cutting;

2009started to co-design THC with Messer China, and developed XPTHC-200; Koike started to use CHC-200DII

2010made XPTHC-100III

2011Made new generation THC, XPTHC-300, and CHC-200E.

2012designed DC version cap THC for Zinser, and new laser CHC-300.
