HYD-XPTHC-100III Torch Height controller

Description

Basic functions
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(breakaway kit).
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-100, even in Manual Control Model, user doesn’t need to worry about torch head crashing.
C、 Freeze Auto Height Control on Corner Signal
XPTHC-100 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、 Lifting torch Up on IHS Disabled status.
On IHS Disabled status, jogging torch head down until it reaches workpiece, when Arc Starts, torch head would lift up automatically to the Set Height set via the button SET-IHS.
E、 Lifting Torch Up on TURN ON or Arc Off:
When CNC is TURN ON or Plasma Arc Off, THC would lift torch up for 2 seconds, please notice this Function during commissioning, avoiding the possible damage of limit switch or lift device.
F.   Set Pierce Delay Time.
Set Button Set-PIERE (set Pierce delay time), to delay output this signal, it is a switch signal, set to detect arc voltage lead in THC. Once THC detect arc lead in, it send arc ok signal to CNC to start cut.
Dynamic Pierce works by receiving plasma’s Dynamic Pierce signal ( Kjellberg plasma has this signal) or plasma’s arc feedback signal. After IHS, THC controls plasma start arc, and it lifts torch up when arc strikes. It is to protect the torch tip and electrode; consumables can work longer in this way.
G.   Manual Operation
Many functions can be Manually operated on Operation Panel of XPTHC-100, such as, set Auto/Manual mode of THC, manually control torch Up and Down, IHS test, Arc Start test…..etc.
H.   Arc Voltage Divide
Isolation Voltage Divide, the Voltage Divide ratio is 100:1/50:1. Once Isolation Voltage Divide function damaged, user can also use Non-isolation Voltage Divide on our voltage divider.
