WSE系列方波交流焊机的使用与维修

Maintenance and using of WSE series square waveform AC welder

WSE晶闸管电抗器式矩形波交/直流焊机可以实现多种焊接工艺。在无焊机电路图纸的情况下,根据焊机无输出空载电压的故障现象,以焊机的基本工作原理为指导,分析故障原因,最终确定焊机无电压输出为控制电路板上整流器虚焊所致。

WSE SCR（silicon controlled rectifier） reactor type rectangle waveform AC/DC welder can realize various welding technologies. When there is no circuit diagram of the welding machine, according to the malfunctions of the welding machine without output of noload voltage.Under the basic principle of welder, analysis the cause, confirm the fault that the Welding machine without voltage output caused by virtual welding of rectifier in control circuit boards.
