摘　　要：根据旧式焊接机应用中存在的问题来确定改造方案,对链条焊接机控制电路进行了设计、改造,将接触器开关改为无触点开关,把控制焊接时间的行程开关用电子定时控制,同时设计电压反馈电路来控制电源电压的波动,以稳定焊接电流。This paper describes an innovation and reconstructive design to solve the existing issues in the current welding machine application. This design adopts non-contact switch to replace contact switch and also adopts electronic timing controller to replace time travel switch for controlling welding time. In this design, a new voltage feedback circuit is designed to control the power supply voltage fluctuations to supply a stable welding current.

关 键 词：无触点开关 定时控制 焊接电流控制
