THC key features as follow,
A, Auto Initial Height Sensing(IHS)
Torch Retaining Cap IHS and Proximity Switch IHS, 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.
D. Set Pierce Time
Set the Button (Set PIERCE) to set Pierce Time.
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.
