我们在使用AG一18型自动氩弧焊机时，发现该机引弧较难。该机采用脉冲引弧，在一个工频周期内，只产生一个脉冲，这是引弧较难的原因。怎样保留脉冲引弧的特点，又能提高引弧性能，对更好地使用该机和对使用脉冲引弧的焊机都有意义。1多脉冲引弧电路原理脉冲引孤是继高频引弧之
When we use the AG-18 automatic argon arc welding machine, we found it is more difficult to arc. The machine uses pulse ignition, in a power frequency cycle, only produce a pulse, which is more difficult arc start. How to retain the characteristics of pulse ignition, but also improve the arc performance, the better use of the machine and the use of pulse arc welding machine are meaningful. A multi-pulse arc ignition circuit principle Pulse induction is following the high-frequency arc
