| Abstract: | The hardware and software design of a digital control system based on two pieces of 80C196KB MCU is introduced in this paper.By adopting keyboard and liquid crystal display,a man-machine interface has been designed,which can set and display submerged arc welding parameters easily and directly.And controlled by PI algorithm with different error calculations,the welding power source acquired the output characteristics of constant current,constant voltage,slow and quick current descending.Wire feeding velocity performs motor armature voltage feedback and arc voltage feedback respectively by two PI adjusters.The submerged arc welder presents good performance in stability,reliability,adaptability and operates easily. |
