摘要
介绍一种利用双向晶闸管作为焊机功率调节元件，并经桥式整流、滤波获得焊接电流的新型焊机，该焊机具有线路简单、工作可靠、成本低、体积小、节能等特点。
A kind of new portable welder was researched out in which the welding current was obtained by using two-way thyristor regulater,bridge-type rectifier and filter.The welder has the features of simple circuit,reliable operation,low cost,minor volume and low power consumption etc.
