[0028] 1. By arranging a base 100 with a bearing 210 and a tray 220 at the lower end of the vertical pipe, the welder rotates the vertical pipe to rotate the welding blind area, thereby making welding simpler and more convenient. During welding, the welder has a large operating space, thereby improving the welding quality and solving the problem that the welding space is small and difficult to weld. At the same time, it avoids the problem that the welding space is small, automatic welding is prone to welding defects, and the welding standards cannot be met.

[0029] 2. By setting a leveling component 300 under the base 100, the flatness of the installation is ensured to avoid deflection of the vertical pipe when rotating and loosening of the wall. At the same time, by adjusting the height of the leveling component 300, the installation and removal of the base 100 are simpler and more convenient, and the operation is easier.
