Plasma cutting, due to melt, the small mouth above, there is always a downward section incision, don't like probably as vertical flame cutting, this is a worldwide problem.
等离子切割，由于融口上面大，下面小，切口断面总有一定斜度，不可能象火焰切割一样垂直，这是一世界性难题。
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。
In addition, plasma jet from the form into consideration, the jet from the gun in diameter is expands outward, nozzle increase in altitude inevitably lead to increased width incision.
另外，从等离子射流的形态方面考虑，射流直径在离开枪口后是向外膨胀的，喷嘴高度的增加必然引起切口宽度加大。
