In order to ensure the continuity of the welding wire 5 in the wire feeding process, a spot welding mechanism 13 is required to weld the welding wire 5 on the two wire reels together, specifically, the first guide pipe 10 and the second guide pipe 11 are both obliquely arranged, so that the welding wire outlet of the first guide pipe 10 and the welding wire outlet of the second guide pipe 11 are close to each other, and the spot welding mechanism 13 capable of welding the welding wire 5 on the first wire reel 1 and the welding wire 5 on the second wire reel 2 is arranged below the welding wire outlet of the second guide pipe 11. When the welding wire 5 on the first wire reel 1 is about to be used up, the welding wire 5 on the second wire reel 2 can be conveyed to the welding wire outlet of the second guide pipe 11, and the head of the welding wire 5 on the second wire reel 2 is welded with the tail of the welding wire 5 on the first wire reel 1 by the spot welding mechanism 13, so that the continuity of the welding wire 5 is ensured, and the process of strip steel welding is not influenced.

The gap between the pressing wheel 302 and the straightening wheel 304 can be adjusted by adjusting the bolt 303 so as to be suitable for welding wires 5 with different diameters and ensure the straightening precision of the welding wires 5. Similarly, a second groove (not shown in the figure) for the welding wire 5 to pass through is arranged in the middle of the wheel surface of the pressing wheel 302.
