一、前言在毛主席“独立自主,自力更生”方针的指引下,经过无产阶级文化大革命我国自行设计、制造的弧焊整流器有了很大发展,为我国的焊接领域增添了一支生力军。“任何新生事物的成长都是要经过艰难曲折的。”弧焊整流器也不例外。和直流弧焊发电机相比,尽管弧焊整流器重量轻,体积小,好维修,好制造,噪声低,效率高,但是以往由于它的性能不够稳定,焊接适应性较差,这就严重影响了弧焊整流器的声誉和发 I. Foreword Guided by Chairman Mao’s principle of “independence and self-reliance,” the arc welding rectifier designed and manufactured by our country through the Great Proletarian Cultural Revolution has made great strides and added a new force to the field of welding in our country. “Anything new is going to have to go through a lot of twists and turns.” Arc welding rectifiers are no exception. Compared with the DC arc welding generator, although the arc welding rectifier is light weight, small size, good maintenance, good manufacturing, low noise, high efficiency, but in the past because of its performance is not stable enough, poor adaptability to welding, which seriously affected Arc Welding Rectifier’s reputation and made
