2, height controller: could change the auto cutting height at any time

3, two modes of the setting arc volt:

A, Setting arc volt mode: set the setting arc volt on the operation panel, let the THC work on the setting arc volt status. It’s the traditional work way.

B, sampling arc volt is the setting arc volt: when the THC control the torch finish the HIS and plasma start, and CNC controller open the AUTO signal to THC, and THC will test the arc value as the setting arc when at beginning the AUTO status. It’s suitable for some small plasma.

4, High Sensitivity: adjusting the THC’s sensitivity, could realize the arc volt change 1V, the arc voltage output will change 1.5V~4V, and don’t occur the vibration. So the lifter’s start voltage is closed related to the THC’s sensitivity, Our lifter’s start voltage is 1.5V ~2V.

Stand alone THC, works with almost any plasma cutter, sale over 2000 sets per year
No need software, all functions can be easily operated on THC(as picture showed)
1. New operation pane,
2. Support Dynamic pierce
3. Better anti-interference.

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 (optional ).
B.Torch Anti-Collision Function
We designed Touch-Up circuit for Anti-Collision Function. No matter it is on Auto Control Model or Manual Control Model, when torch head touches the workpiece, THC would automatically lift torch up to IHS height. So with XPTHC, even in Manual Control Model, user doesnt need to worry about torch head crashing.
C. Freeze Auto Height Control on Corner Signal
XPTHC can recognize Corner Signal from CNC and freeze Auto Control Model on receiving this signal, 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 (Corner Turning, Kerf Crossing) effectively.
D. Set Pierce Time
Set the Button (Set PIERE) 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. And XPTHC-100 supports different HF plasma.
