Single-power-supply double-wire gas shielded welding device

The single-power-supply double-wire gas shielded welding device comprises a machining box, an electric push rod is fixedly connected to the top of an inner cavity of the machining box, a gas shielded welding machine is fixedly connected to the telescopic end of the electric push rod, and an adjusting box is fixedly connected to the bottom of the inner cavity of the machining box. The two sides of an inner cavity of the adjusting box are movably connected with right-hand and left-hand threaded rods through bearings. Through the arrangement of the machining box, protection can be carried out during gas shield welding, welding slag is prevented from splashing to hurt people, through the arrangement of the electric push rod, the height of the gas shield welding machine can be automatically adjusted, automatic welding operation is achieved, and through the arrangement of the adjusting box, the right-hand and left-hand threaded rod, the threaded sleeve and the clamping plate, the welding efficiency is improved.
