Carbon dioxide gas shielded welding device

The invention relates to the technical field of welding equipment, in particular to a carbon dioxide arc welding device which comprises an electric welding machine body, a moving structure is arranged at the bottom end of the electric welding machine body, a dustproof structure is arranged outside the moving structure, and a driving structure is arranged at the top end of the electric welding machine body. A storage structure is arranged at the end of the driving structure, a rotating structure is arranged on one side of the electric welding machine body, and an adjusting structure is arranged at the end of the rotating structure. The electric welding machine body is moved through the moving structure, and the carrying efficiency of the electric welding machine body is improved; dust is prevented through the dustproof structure, and the heat dissipation effect of the electric welding machine body is improved; the driving structure drives the storage structure to rotate, so that the storage structure stores th
