The cutting quality of a plasma arc cutter depends greatly on the momentum and energy distributions in the transferred arcjet. In this paper, using the result of integral analysis for the boundary layer equations of transferred arcjet, the correlations between the momentum loss of the arcjet and the operating conditions of a plasma torch such as arc current, gas flow rate, and cutting stand off were investigated. Furthermore, in order to study the actual effect of the momentum loss on the cutting performance of an unmodified plasma cutting torch (Komatsu G940), the relations between the calculated magnitudes of the momentum loss and the maximum cutting speed for the sheet metals of various thicknesses have been investigated by using a numerically controlled plasma cutting table.
