But the argon plasma arc voltage, low enthalpy is not high, cutting ability is limited, and cut the air than the thickness of the cut about 25% lower.
但氩气等离子弧的电压较低，焓值不高，切割能力有限，与空气切割相比其切割的厚度大约会降低25%。

A staircase at the center of the arc provides circulation between the upper and lower levels.
在场地的圆弧中心设置了一个楼梯供上下两块场地之间的流通。

It is regarded that the lower dilution rate is related to homogeneous distribution of temperature and pressure of the arc and deoxygenization of the arc gas.
