Due to compression process influence the air dew point of compressed air in the pipeline, run it will gradually decrease temperature, so the compressed air system always have liquid water.

由于压缩过程影响空气的露点，压缩空气在管线中运行时温度会逐渐降低，所以压缩空气系统中总是有液体水存在。

Increase the compression degree can make arc of high temperature plasma jet extended, form more uniform high temperature area, and increase the speed of the jet, can reduce the width of the poor.

增加电弧的压缩程度可以使高温等离子射流延长，形成更为均匀的高温区域，同时加大射流的速度，可以减小切口上下的宽度差。
