condenser discharge welder

A new type of capacitor-discharged welder is researched and developed The welder use SCR as its control switch ,and the current circuits in the welder transformer in conflict direct in turn ,and the welder is isolated from the electric net when welding .

本文研究开发了一种新型的电容贮能焊机，其主电路采用晶闸管作为控制开关，使电流轮流反向流过焊接变压器，且电容放电时焊机与电网隔开；其控制电路采用了CMOS集成电路，可以对焊接和休止时间进行予置和准确计数，并推动程序自动转换。
