Sometimes nitrogen are being used oxygen plasmaarccutting of arcs gas.
有时氮气还被用作氧等离子弧切割时的起弧气体。

Now the plasmaarccutting machine part on gas pressure to control the flow, because when gun aperture, the gas control certain pressure and you control the flow.
现在的等离子弧切割机大多靠气体压力来控制流量，因为当枪体孔径一定时，控制了气体压力也就控制了流量。

High-speed plasmaarccutting technology plasma engineering hot metal cutting, and partial melting with high flow will also be the molten metal blow, form a narrow incision.
