FIELD: welding; device to feed welding wire and supply of welding current to wire. SUBSTANCE: in method of consumable electrode arc welding performed with zigzag deformation of welding wire, wire deformation is performed with pitch equal to from half to two thirds of length of current-carrying tip and by value equal to difference in size of hole in tip and welding wire. Wire bending is adjusted as tip wears out. EFFECT: enlarged operating capabilities. 2 dwg, 1 tbl
