Zusammenfassung:	FIELD: welding technology. SUBSTANCE: this is intended for feeding welding wire to welding zone and can be used in various branches of mechanical engineering. In pulse feeding mechanism, when electric power is supplied to coil 5 armature 6 is retracted into it and pulls armature 8 with itself. At this moment, clamp 11 is wedged to lock wire 12. Clamp 16 is freely sliding along wire. After electric power is switched to coil 7, reverse process takes place, that is armature 8 is retracted into coil 7 and pulls clamp 16 and armature 6 with it. In this case, wedged is clamp 16 and together with armature 8 it pulls wire 12 with itself, and clamp 11 releases it at this moment. EFFECT: higher efficiency. 1 dwg øøø1
