Abstract

In this paper was obtained the analytical dependence of the total and voltage power of the plasma arc on the arc current and the flow rates of argon and nitrogen of the serial plasma-gun Metco F4. It is established that an increase in nitrogen consumption has the greatest effect on the increase in arc voltage. A computational and graphical technique for estimating the average temperature and the velocity of the plasma flow at the cutoff of the nozzle of the serial plasma-gun Metco F4 is proposed.
