FIELD: process engineering.
SUBSTANCE: invention relates to welding equipment, particularly to current feed nozzle for welding to narrow cut at welding of 300-500 mm thick vessels operated at pressure, etc. Current feed nozzle comprises flat casing with welding wire feed channels and those for pendulum tip cylindrical rod and flexible lead-in. Said tip is articulated with said casing and consists of fixed pendulum contact plate and movable contact plate. Symmetric rectangular slots with semi-cylinder grooves are made at lateral surfaces of the casing and pendulum fixed contact plate mating surface. Flexible lead-in consists of several twisted conducting wires fitted in said semi-cylinder grooves and locked by pressure plates having appropriate semi-cylinder grooves tightened by threaded elements.
EFFECT: longer life, higher quality of welding.
