| Abstract: | This paper analyses the process of plasma arc cut.The arc voltage sampling circuit puts voltage signal into singlechip by A/D switching,and then signal which is sent out from I/O interface controls cutter adjusting electromotor by direct current pulse breadth timing circuit.Finally the auto-adjustment control of the NC plasma cutter is achieved in the process. |
