双弧现象及其影响在等离子切割、焊接过程中,由于规范参数选择不当,或枪体设计不合理,而经常产生双弧。在非转移弧型的多级阳极等离子体发生器中,也会发生类似于双弧的所谓串弧现象。双弧不仅是使阳极或喷咀烧损和产生工艺缺陷的重要原因,更主要的是限制了等离子体发生器的使用电流和使用功率的提高。 Double arc phenomenon and its impact Plasma cutting, welding process, due to improper selection of the normative parameters, or the gun body design is not reasonable, and often double arc. In a non-transfer arc type multi-stage anode plasma generator, a so-called series arc phenomenon similar to double arc also occurs. Double arc is not only the anode or nozzle burned and process defects caused by an important reason, more importantly, limits the use of plasma generator current and use of power.
