FIELD: mechanical engineering; gas-shielded arc welding. SUBSTANCE: torch has gas-permeable porous insert made in the form of taper bushing installed coaxially to electrode. Bottom inner diameter of insert equals diameter of entrance section of nozzle and its top part functions as supporting surface for electrode holder. Total area of through pores of insert is not less than that of exit section of nozzle. EFFECT: improved service life of torch when operating at high currents; reduced size. 1 dwg
