PTHC-200DC is our new stand alone THC in 2013, comparing to old XPTHCs, it has new features as follow,
Torch Retaining Cap IHS( ohmic contact) and Proximity Switch IHS both available, Proximity Switch IHS is for cutting dirty/rusty workpiece, needing the Anti-Collision Fixture designed by HYD (breakaway kit ). It supports underwater cutting,too.
When torch tip touches workpiece, THC automatically lift torch up to IHS height to avoid crashing. It is effective both on Manual/Auto mode.
XPTHC-300 would freeze Auto Mode on receiving corner signal from CNC system to avoid torch diving on Cycle start/end, corner turning.
