分析等离子电弧切割过程,通过弧压采样电路将采样电压信号经A/D转换送入单片机,由I/O口输出控制信号经直流脉冲宽度调速电路控制切割枪高低调节电机,可实现数控等离子切割枪自动高低调节控制.

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 p...
