我厂广大职工在厂党组织领导和支持下,依靠集体智慧和力量,于1977年5月试制成功自调电感 NBC-400A 二氧化碳焊机,并在1977年9月得到上海沪江机械厂领导的大力支持和工人师付积极帮助下,完成焊机初步调试工作。于10月17日至20日在上海进行了技术座谈会。现将该机简介如下。一、NBC-400A 自调电感焊机原理和特点:1.能在负载情况下对焊接电压、电流进行无级调节,在调节电压的同时,相应自动地调整了电感,工作电压愈高,相应的电感值愈大;相反亦然。这样,就甩掉了笨重的输出电抗器,使在粗、细丝焊接时成型好,飞溅少。
Under the leadership and support of the factory party organization, a large number of staff and workers of our factory relied on the collective wisdom and strength to produce the self-adjusting inductance NBC-400A carbon dioxide welder in May 1977 and got the leadership of Shanghai Hujiang Machinery Factory in September 1977 Strong support and workers to pay the positive help, to complete the welding machine preliminary commissioning work. Held a technical symposium in Shanghai from October 17 to October 20. Now the machine profile is as follows. First, the NBC-400A self-inductance electric welder principle and features: 1. Under the load conditions of the welding voltage and current stepless adjustment, while adjusting the voltage, the corresponding automatically adjust the inductance, the higher the operating voltage, the corresponding The larger the inductance, the opposite is true. In this way, get rid of bulky output reactor, so thick, thin wire forming a good spatter.
