PURPOSE: A welding rod winding device for an automatic elbow tube welding device is provided to achieve the optimum winding of a welding rod bundle by controlling the diameter of a welding rod winding unit or the width of a welding rod binding unit according to the amount of winding a welding rod. CONSTITUTION: A welding rod winding device for an automatic elbow tube welding device comprises a base(110), a housing(120), a plurality of axial guides(130), a slide axis(140), a welding rod binding unit(150), a handle(160), and an axial driving unit. The base is coupled with a leveling stage(8). The housing is projected from the center of the base and has a plurality of link guide grooves(121). The axial guide is arranged in the radial direction of the housing on one side of the base and has a rib guide groove(131). The slide axis comprises a rib(141) which is guided along the rib guide groove. The welding rod binding unit controls the width of a welding rod bundle according to the amount of winding a welding rod(4). The handle is installed on an end of the housing. The axial driving unit, which comprises a bolt shaft, a reciprocating nut, a fixing link(173), and a coupling link(174), linearly reciprocates the slide axis along the axial guide when the handle is turned.
