The invention relates to an auxiliary welding device, in particular to an auxiliary electric soldering iron pushing and welding device. The invention aims to provide the auxiliary electric soldering iron pushing and welding device capable of reducing the labor intensity and convenient to use. The invention provides the technical scheme that the auxiliary electric soldering iron pushing and weldingdevice comprises a clamping device, a shell, a motor, a first gear, a second gear, a first guide rod, a pulling plate, a flat plate, a third gear, a hanging rod, a first spring and the like, whereinthe shell is rotatably connected onto the fixed clamping device; the motor capable of driving the first gear to rotate is arranged on the lower part of the front side surface in the shell; and the first gear is fixed onto an output shaft of the motor. According to the auxiliary electric soldering iron pushing and welding device provided by the invention, through the clamping device, a user can conveniently weld iron; and the second gear anticlockwise rotates to be matched with the third gear, so that a welding wire can be conveyed leftwards, iron welding can be carried out without the need forusing both hands, and the labor intensity of the user can be reduced.
