<P>PROBLEM TO BE SOLVED: To provide a wire guide disposed to a wire feeding passage between a welding wire spool or a pack wire, and a welding wire feeding device to prevent increase in feeding resistance. <P>SOLUTION: A guide roll 12 has a groove 12a formed to an outer peripheral part thereof so that the welding wire 3 fed from the wire supply source 2 is put in the groove 12a. The guide roll is held on a base end side of a guide body 11 to be rotatable by being driven along with the feeding. On a tip side of the guide body 11, an insertion member 14 having a feeding hole 13 from which the welding wire 3 is fed, is attached, and a holding member 16 holding an outer periphery of the insertion member 14 to be rotatable around an axis in parallel with the feeding hole 13, is provided. When an insertion angle of the welding wire 3 into the guide roll 12 is changed, the guide body 11 rotates around the axis in parallel with the feeding hole 13 following the change in insertion angle to prevent increase in feeding resistance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
