弧焊电源外特性的直观显示——用示波器显示弧焊电源外特性

DIRECT DISPLAY FOR EXTERNAL CHARACTERISTIC OF ARC WELDING POWER SOURCE

利用示波器显示弧焊电源的外特性,能较直观,准确地显示出来.介绍了微机的外接口电路、采样电路和外特性曲线的形成原理,使电焊机的制造在现代化管理方面又进了一步.

The external characteristic of are welding power source is displayed with oscillograph which possesses direct and accurate manner. Interface of outer circuit for computer, acquisition circuit and principle of formed extemal characteristic curve are introduced in the paper. It is a further step for advancing administration of welding machine manufacture.
