PROBLEM TO BE SOLVED: To solve the problem that, in a case of application to a work piece of complex shape, an optimum welding posture is not obtained because of avoidance of contact or interference between a filler wire guide device and the work piece, and even in a case of minute interference with the work piece, position of the filler wire guide device goes wrong, resulting in redoing of adjustment work or production of an article with defective welding.SOLUTION: A fitting arm 14 contains a slot 20 extending in first direction. An adjustment member 30 is fitted to the slot 20 for positional adjustment in a first direction, and contains a guide groove 30a extending in a second direction orthogonal to the first direction. A fitted part 64 contains a slot 66 extending in the second direction, and is fitted to the guide groove 30a for positional adjustment in the second direction. A bolt 80, in a condition in which the slot 20 intersects with the slot 66, adjusts and fixes position of the fitted part 64 in the second direction. The first direction and the second direction are contained in a common virtual plane, and the second direction is in the same direction as axial center O of a welding torch 10. |
