The invention discloses a stepless adjustable eccentric rotation consumable electrode gas protection welding gun. The stepless adjustable eccentric rotation consumable electrode gas protection welding gun comprises a drive device, an eccentric device, a gas protection device and electric conduction rods. The drive device comprises a hollow shaft torque motor, a connecting sleeve, an encoder and the like. The movement of the motor is accurately controlled through the encoder and the driver. The eccentric device comprises a bearing inner sleeve and an eccentric sleeve. During welding stick eccentricity achieving, a smooth transition process exists, and an overall mechanism of the welding gun is more simple and smaller in power consumption. The gas protection device is arranged at the lower end of the eccentric device. When the motor rotates, the upper electric conduction rod, the bearing inner sleeve, the eccentric sleeve and the lower electric conduction rod are driven to rotate, and the lower end of the lower electric conduction rod is connected with an electric conduction nozzle, so that a welding stick does the cylindrical rotation; by utilization of the stirring action of a rotating arc to a molten pool, the welding line structure is refined, the welding line tenacity is improved, the fusion depth of the two sides of a welding line is improved, and the forming and welding quality of the welding line is improved. The overall structure is simple, an eccentric mechanism is simplified, the application range is wide, and automation is easy to achieve.
