传统的等离子弧焊熔透适应控制器由于脉冲的峰值、基值脉宽随时间而变,因此,工件在冷态时,峰值脉宽拉得较长,基值脉宽较短,电流的平均值较大。为此本文介绍了一种可大量节能的监控器,是调幅型的,不但具有简单、经济、节能的优点,而且不需要预热时间,解决了预热时间与焊缝熔深之间的矛盾,从而提高了引弧处的质量。 Traditional plasma arc welding penetration controller due to the peak pulse, the base pulse width changes with time, so the workpiece in cold state, the peak pulse width to pull longer, the basic pulse width is shorter, the current average Larger value. To this end, this paper introduces a large number of energy-saving monitor is amplitude modulation type, not only has the advantages of simple, economical, energy saving, and does not require warm-up time to solve the preheating time and weld penetration between the contradictions , Thus improving the quality of arc start.
