摘要： A torch with a turbulized supply of a plasma forming gas comprises an electrode having a high-melting insert and a flat end face, and a nozzle with an internal surface having two mated portions: one cylindrical and one tapering; and the diameter of the electrode flat end face amounts essentially to 0.4-0.5 diameter of the electrode proper and the radius of conjugation of the nozzle cylindrical and tapering portions is equal essentially to the length of its cylindrical portion. Due to such a design, the inventive torch features a long service life of both the electrode and the nozzle.
