摘　　要：从弧长稳定控制出发，分析了变速送丝系统的放大倍数对弧长稳定性的影响，研制了用ＰＩＤ调节器和专用晶闸管移相触发器组成的电弧电压反馈式闭环控制孤长的系统集成化电路。使其既适用于埋弧自动焊，也适用于粗丝气体保护自动焊。This essay begins from the control of arc stabilizer,analyzing the influence of magnifying multiple of gearing wire-convey system on the control of arc stability;developing the systematic integrated circuit of which the arc is controled by the arc voltage feedback close ring controled with PID adjustor and special phase shift trigger;making it be used for both automatic sybmerged arc welding and co 2 gas shieleled welding with bold wire.
