The present invention relates to a spot welding device and, more specifically, to a spot welding device capable of differentiating the heights of an upper and lower welding guns, replacing a support block to support a lower welding gun in accordance with the welding points of a product having protruded portions or recessed portions to enable a user to conduct a spot welding; thus becoming capable of welding various products having different welding points while using a single spot welding device to enhance working efficiency as well as productivity. In accordance with the various shapes or types of the object being spot-welded, the support block can be replaced to fit the product. Therefore, the welding points of the upper and lower welding guns can be matched. By the same, when performing independent spot welding works on different products manufactured by different automobile companies, the support blocks fitting the respective welding points are replaced; thus, the objects being welded, such as the different types of automobile cargo box doors, can easily be spot-welded and the increase in productivity and work efficiency can be obtained. By using a moving guide body, the object being welded can be moved along a longitudinal direction during spot welding, and the accuracy of the spot welding can be enhanced by fixating the object onto the moving guide body. |
