我单位使用的电焊机,绝大多数为 BS—330型交流电焊机,其容量21千伏安,电流调节范围为50～450安。根据历来施工的情况,普遍都采用直径为2.5、3.2及4.0毫米三种规格的电焊条,所需电流在50～230安即可,还有一半没有利用。能不能充分地发挥设备的潜力,为国家节约财富?工人师付提出了这个问题并通过实践,反复改革,终于将一台 BS—330焊机改成两人可同时操作的焊机,从而提高了设备的效能。 The welding machines used by our company are mostly BS-330 type AC welders, with a capacity of 21 kVA and a current adjustment range of 50 ~ 450 Amps. According to the history of construction, the commonly used diameter of 2.5, 3.2 and 4.0 mm three specifications of the electrode, the required current in the 50 to 230 A can be, and half did not use. Can not fully develop the potential of the equipment for the country to save money? Worker teachers paid this question and through practice, repeated reform, and finally will be a BS-330 welder into two simultaneous operation of the welder, thereby enhancing The effectiveness of the equipment.
