为了节约更多的电力,支援工农业生产,抚顺市第一建筑工程公司三工区试制成功一种简单实用的交流弧焊机节电开关。经实际使用和现场会议鉴定,认为与同类型的开关相比,结构简单,制作容易,操作灵活,只要电焊条与工件接触即能很快自动送电,不用时可在预定的延长时间内自动断开,达到节约电焊机空载电流之目的,同时还具有维修方便,工作可靠等优点。 In order to save more electricity and support industrial and agricultural production, Fushun City First Construction Engineering Company Sangong District has successfully implemented a simple and practical AC arc welding machine power saving switch. After actual use and on-site conference identification, it is considered that compared with the same type of switch, the structure is simple, the production is easy, and the operation is flexible. As long as the welding electrode is in contact with the workpiece, the power can be automatically transmitted quickly, and when it is not used, it can be automatically performed within a predetermined extension time. Disconnected, to save the no-load current of the welding machine, but also has the advantages of convenient maintenance and reliable work.
