WELDING WIRE PULSED FEEDER Russian patent published in 1997 - IPC

FIELD: mechanical engineering; welding. SUBSTANCE: with voltage applied to winding of coil 4, armature 9 moves towards core 2, and on return motion grips wire 13 by grip 14 and feeds it to welding zone. Amplitude of armature 9 is adjusted by shifting core 2 in housing 1 with subsequent fixing by bolt 3. Oscillation frequency of armature 9 is increased by decreasing release time. Effort of forcing wire 13 in guide hose and nozzle is adjusted by rigidly of resilient plates 6 which, in its turn, is adjusted by positioning of nuts 7 on shank 8 of armature 9. EFFECT: enlarged operating capabilities. 1 dwg
