Therefore, although the manual welding work requires skill, in recent years, the number of skilled welding workers has decreased due to a serious labor shortage, and manual welding work may be performed. It's getting harder. When performing the welding work by hand, the welding worker must wear special glasses or the like to protect the eyes from the ultraviolet rays of the sparks generated by the welding, and to prevent fire due to the scattering of the welding sparks. Therefore, there was a problem that it was necessary to cure the surroundings. Further, when welding work is performed at a high place, there is a risk of falling and the like, and it is troublesome that a stepladder and a rolling scaffold must be assembled each time the work is performed. Furthermore, when plumbing work is done in a small space,
There is a problem that the welding work cannot be performed because the welding rod cannot reach the desired welding location.

Further, in this embodiment, the motor 4 which is a component of the driving means is housed in the base 1, and the motor 4 and the gear 707 of the gearbox 705 are connected by the flexible shaft 13. However, the motor may be provided in the gear box 705 and the gear 707 may be directly attached to the motor shaft. Further, in the present embodiment, the case where the pipe 30 having a circular cross section and the existing pipe 40 are welded has been described, but for example, a welding rod guard is swingably provided on a rotating frame and a spring or the like is urged. If the welding rod guard is biased toward the center of the rotary frame by the means, the device of the present invention can be applied to welding pipes and other members having a cross-sectional shape other than a perfect circle, such as an ellipse or a rectangle. it can.

As described above, according to the present invention, the tip of the guide member that supports the welding rod so that it can be paid out, the rolling wheel that can come into contact with the object to be welded, and the welding rod is rotated by the rotation of the rolling wheel. Since a feeding mechanism is provided, and further, a drive means for moving the guide member along the welding object, and a power source for supplying an electric current to the welding rod are provided.
It is possible to automatically perform the welding work of the object to be welded. Therefore, even a non-skilled worker can easily perform the welding work, and it is not necessary to wear special glasses or the like.
Workers can be freed from dangerous and troublesome work at height.
