脉冲喷射过渡为该工艺设计的专用电源能将焊接电流以毫秒级从弱的基值电流切换到很强的峰值电流 ,这种“切换”或“脉冲”可建立一个非常稳定的弧态。在基值电流维持电弧不熄灭时 ,只有在峰值电流时才会产生熔滴过渡。熔滴小到类似于喷射时的细滴 ,产生的飞溅也很小。操作时的 Pulsed Jet Transition A dedicated power supply designed for this process switches the welding current in milliseconds from a weak base current to a very strong peak current. This “switching” or “pulse” creates a very stable arc. When the base current does not extinguish the arc, the droplet transition will occur only at the peak current. The droplet is small enough to resemble a fine droplet when sprayed, producing very little spatter. When operating
