PURPOSE: A spot welding gun is provided to improve work efficiency by installing a holding member for holding the spot welding gun, thereby controlling work load easily and enable welding operation of high quality to be done by installing angle adjusting gear and angle fixing lever, thereby efficiently adjusting angle. CONSTITUTION: The spot welding gun(100) comprises a body(10); a welding gun assembly(20) comprising arm(21) rotationally installed at the body, first holder(23) connected to the front end of one side of the arm, second holder(25) connected to the front end of the other side of the arm and moved back and forth with being penetrated into the body, first welding protrusion(27) connected to the front end of the first holder, and second welding protrusion(29) connected to the front end of the second holder; an angle adjusting gear(30) installed between the body and welding gun assembly so that the angle adjusting gear is rotated by rotation of the welding gun assembly; a holding member(40) connected to the outer side of the body; an angle fixing lever(50) one side of which is rotationally connected to the front end of the holding member, and at the other side of which a subsidiary gear(51) to be connected to the angle adjusting gear is installed to fix the angle adjusting gear; and a bracket(60) at one side of which a catching protrusion(61) locked to catching members(55) connected to the second holder is formed, the other side of which is rotationally connected to the body, and to the outer surface of which a hydraulic pressure adjusting lever(65) is connected.
