Study of Mutiple Program Spot Welding Controller

本文主要介绍了多程序点焊控制箱的程序过程以及主控制器及调制器的工作原理，并采用了一种新型的触发电路代替传统的脉冲变压器，具有触发可靠、大功率、高精度、电路简单等特点。

The program proceeding of mutiplc program spot welding controller and the operationprinciple of main controller and modulator are introduced in this peper.A new trigger circuit is described.Itis good circuit to instead of pulse transformer.It has high accuracy phase angle,large transfer area and isvery simple.
