Trolley for electric welding operation

The utility model belongs to the technical field of electric welding construction, and solves the problems that a large amount of welding fume is generated in the electric welding operation, and if the welding fume is not treated in time, environmental pollution and occupational diseases are caused; and in case of sudden weather, water is inconvenient to discharge after entering the box body, so that structures such as an internal electric welding machine can be corroded. A trolley frame comprises a bottom frame, a top frame and a side frame connected between the bottom frame and the top frame, a push rod is fixed to the rear portion of the side frame and reinforced through an inclined strut, the bottom frame is sealed through a bottom supporting plate, a drainage hole is reserved in the bottom supporting plate, and an electric welding machine, a switch box and a welding fume purifier are all fixed to the upper end of the bottom supporting plate. A pipe arm of the smoke welding machine purifier crosses a cros
