PTHC-II plasma arc-voltage torch height controller

Plasma arc-volt height control a high degree automation of the torch height, using the change of the arc height following the change of the torch and the work piece height while cutting. 

Main characters : 

• High-performance microprocessor is the core of plasma arc-volt height control; it adopts high-pressure Isolation Amplifier; PWM control output.
• Partial pressure ratio fit a variety of input; 
• For a given arc voltage and the actual arc voltage integrated display; 
• Upon request, select the appropriate arc voltage accuracy. 
• Arc voltage control accuracy of the adjustment range can be ± 1V-～± 5V (50:1 or 100:1)
