Package inclide :
XPTHC-300-PT one set (Include the PCB for retaning cap IHS and HV retaning cap cable)
1,stand alone THC for portable, small plasma cutting machine
2. support different HF plasmas, CNC controllers.
Basic Functions of XPTHC-300-PT
Auto Initial Height Sensing(IHS), Dual speed IHS :
When XPTHC-300-PT auto IHS , it use Dual speed IHS. It automatically calculates the fast-falling delay according to the rising delay set by the P8 parameter, then switch to slow down. After the positioning signal is detected, the torch will rise rapidly and finish IHS. Dual speed IHS can better protect the torch, and can improve the positioning accuracy. When the P8 parameter set less than 6 , Dual speed IHS cancel.
Proximity Switch HIS
XPTHC-300-PT use NPN Proximity Switch , In normal operation, the switch is in contact. The proximity switch can be replaced with a contact switch also. In any state ,when the torch touch plate and when detection circuit action , XPTHC-300-PT will control the torch in IHS position. The distance between torch and plate , can be setting by “IHS HEIGHT” key. If the proximity switch in dis-contact state, THC will control torch rise up rapidly , until to up limit , in the same time will have collision signal. The proximity switch with anti-collision function.
Retaining cap IHS
Use retaining cap IHS require plasma with metal retaining cap. During IHS process, according to torch touch plate triggering signal. After THC receiving the signal, will control torch rise up to IHS position. This function requires the user to choose when ordering.
Setting Arc volt and Actual Arc volt monitoring function:
Before arc start, the display shows set arc.
After send arc start signal and detected the arc signal, display shows Actual volt according to pierce delay.
Complete cutting the torch lifting automatically:
When cnc controller closed cutting signal, THC will control the torch rise up time (P8 parameter setting), will protect torch when torch empty run.
Arc enable output (Pierce complate output)：
Set Button “PERICING HEIGHT” set Pierce delay time, to delay output this signal. The signal is detected by detecting whether there has a arc signal, The output signal is the relay switch output . Output by CNC sockets PIN6 and PIN8. PIN8 is COM.
Automatically operation:
After CNC controller send start cutting singal, THC will finish IHS automatically----Arc start----Detected Arc----Pierce delay----Pierce finished. After CNC controller received pierce finished signal, will control machine start cutting until cutting end.
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-300-PT, even in Manual Control Mode, user no needs to worry about torch head crashing.
There are currently no optional accessories for this item.
