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 ).
IHS has two speeds, adjustable to user, protect torch and better accuracy.
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.
D. Set Pierce Time
Set the Button (Set PIERCE) to set Pierce Time. XPTHC-300 support Dynamic pierce on cutting thick material.
E. Manual Operation
Many functions can be Manually operated on THC Operation Panel such as setting Auto/Manual, Up and Down, testing of IHS and Arc Start….etc
F. Arc Voltage Divide
Isolation Voltage Divide detection, the Voltage Divide ratio is 100:1/50:1.
History of HYD Torch height controller
1996 made first capacitive torch height controller (Analog circuit);
1998 made first arc voltage torch height controller (Analog circuit);
2003 designed SCM based PTHC (Ontime);
2004 set 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
2006 made XPTHC-100II, CHC-200DII, and XPTHC-III;
2008 made capacitive CHC-300 for laser cutting;
2009 started to co-design THC with Messer China, and developed XPTHC-200; Koike started to use CHC-200DII
2010 made XPTHC-100III
2011 Made new generation THC, XPTHC-300, and CHC-200E.
2012 designed DC version cap THC for Zinser, and new laser CHC-300.
