摘要：
The secondary and erosion characteristics of the electric-arc plasmatorch were studied experimentally. Formulas for arc voltage calculation depending on helium flow rate, diameter of the inner cavity of cylindrical copper anode, arc current, and distance from the nozzle to metal melt were derived.
