摘要
介绍了ＣＯ２ 气体保护焊收弧时焊接规范、参数进行自动切换， 减小收弧后焊丝端头形成的固态金属熔球直径， 改善了再次引弧时的引弧性能。
This paper introduced retreating the arc of CO 2 welding, the welding parameters were automatically changed After retreating the arc, the diameter of the solid state metal melting ball formed at the welding wire end was reduced Therefore,it improved the next striking performance
