Patent ID: 7105771

Claim:
An arc welding robot comprising a mechanical section, and a welding torch cable accommodating structure comprising: a front arm whose proximal end is provided on the mechanical section; a first wrist element which is provided on the distal end of the front arm and is rotatable with respect to the mechanical section about a first axial line extending in a longitudinal direction of the front arm; a second wrist element provided on the first wrist element so as to be rotatable about a second axial line crossing substantially perpendicularly to the first axial line; a welding torch provided on the second wrist element so as to be rotatable about a third axial line which extends substantially perpendicularly to the second axial line and is spaced from the first axial line by a predetermined distance; a slide mechanism which is provided on the front arm and can move forwards and backwards in a direction substantially parallel to the first axial line; a welding wire feeding apparatus mounted on the slide mechanism; and a guide member provided on the second wrist element for restricting the movement of a torch cable; wherein the torch cable is supported in a rotatable state at a coupling portion between the torch cable and the welding torch.
