Cutting gas is to ensure that the formation of plasma jet, and to ensure that remove the molten metal oxides and incision.

切割气体既要保证等离子射流的形成，又要保证去除切口中的熔融金属和氧化物。

If in the enthalpy increases, reduce the diameter of the jet and increase the gas flow, can often gain faster cutting speed and better cutting quality.

如果在焓值提高的同时，减小射流的直径并加大气体的流速，往往可以获得更快的切割速度和更好的切割质量。

Because the hydrogen can significantly improve the arc voltage, make hydrogen plasma jet has high enthalpy, when mixed with argon plasma jet, the use of cutting ability is greatly increased.

由于氢气能显著提高电弧电压，使氢等离子射流有很高的焓值，当与氩气混合使用时，其等离子射流的切割能力大大提高。

European countries and the United States are cutting back on purchases of expensive jet fighters.
