我厂有一台МТП—75型点焊机,已使用廿余年,变压器和机械械部分尚好,但电控部分元件老化,损坏严重,不能正常工作。而引燃管又属淘汰产品。由于生产需要,我们进行了技术改造,重新设计了控制电路,将引燃管改为可控硅,电子管控制线路改为半导体线路,插接式直流继电器代替电话继电器(7只减少到4只),电路大大简化,经改造后操作、维修都方便。在此基础上对一台ИА—100—4型点焊
I plant a МТП-75 spot welding machine, has been used for more than 20 years, the transformer and mechanical parts are still good, but some of the components of electronic control aging, serious damage, can not work properly. The ignition tube is eliminated products. Due to the production needs, we carried out technological innovation, redesigned the control circuit, the pilot tube to SCR, tube control circuit to a semiconductor circuit, plug-in DC relay instead of telephone relays (7 only reduced to 4) , The circuit is greatly simplified, after the operation of the transformation, maintenance is convenient. On this basis, a ИА-100-4 spot welding
