《焊接》杂志70年第5期、71年第8期等所介绍的改装 BS—330型焊机的经验,虽然有其独特之处,但总的说来,都是需要用导线在原来的二次线圈上再加绕若干圈。能不能不增加线圈数,亦即仅依靠焊机本身的线圈来提高引弧空载电压呢?伟大领袖毛主席教导我们:“一切真知都是从直接经验发源的。”遵照毛主席的教导,仔细分析了 BS—330焊机的电气原理认为,这类焊机在其小电流或大电流两挡工作时,都只使用了其中部分线圈,尚有一部分
The welding experience of modified BS-330 welder introduced in “Welding” magazine No. 5, No. 71, No. 71, etc. has its own unique features. However, in general, it is necessary to use wire in the original The secondary coil plus a few more times around. Can not increase the number of coils, that is, relying solely on the coil itself to improve the arc welding load voltage it? Great leader Chairman Mao taught us: “All true knowledge is derived from direct experience.” In accordance with Chairman Mao’s teachings, Careful analysis of the BS-330 welder’s electrical theory that such welding machine in its small current or high current two-block work, only use part of the coil, there are still some
