前言在生产实践过程中,我们认为硅焊机与旋转式焊机相比虽然有突出的优点,但仍显得结构复杂、体积笨重、成本高。为了赶超世界先进水平,在党支部、革委会的正确领导下,组成了试制小组。参加试制的同志们怀着为伟大领袖毛主席争光的雄心壮志,汇集了三十多个厂矿、院校的意见,经过两个多月的日夜奋战,终于甩掉了硅直流焊机中的“自饱和电抗器”、“稳定器及硒堆”、“控制元件”等笨重复杂结构,设计并制造成功了 ZX—320型三相动铁分磁式硅整流弧焊机。 Preface In the course of production practice, we think that although there are outstanding advantages compared with rotary welders, the appearance of complicated structures, bulky bulks and high costs are still seen. In order to catch up with the world advanced level, under the correct leadership of the Party branch and the Revolutionary Committee, a trial-making group was formed. With the ambition of winning the glory of the great leader Chairman Mao, the comrades participating in trial production brought together the opinions of more than thirty factories, mines and colleges. After more than two months of fighting day and night, they finally got rid of the “ ZX-320 three-phase iron-type magnetic silicon rectifier arc welding machine has been designed and manufactured successfully due to the complicated structure such as ”saturable reactor“, ”stabilizer and selenium pile“ and ”control element".
