The stability of the welding arc depends mainly on the voltage and the gas ionization when current zero-crossing as well as the electron emission ability of the electrode.
其电弧稳定与否，主要取决于电流过零瞬间的电弧空间电离度、 电极发射电子能力及再引燃电压的上升速度。
Besides, the triggering electrode will realize the ionization of xenon gas along the length direction of the discharge spacing that transmits high-voltage pulse.
另外，上述触发电极能沿着传输高电压脉冲的放电空隙的长度方向将氙气离子化。
To strike an the arc, electron emission and ionization of the gas is initiated by withdrawing the electrode from the work surface in a con trolled manner, or with the aid of an initiating arc.
钨极氩弧焊是通过工件表面和电极之间气体的电离和电子的发射来引弧的。
