PURPOSE: A welding robot gun is provided to prevent leakage of coolant when replacing welding protrusion of the robot gun, thereby preventing disorder by the leakage. CONSTITUTION: A welding robot gun comprises a body(10), an upper holder(20), a first welding protruding part(30), a lower holder(40), and a second welding protruding part(50). The upper holder is connected to the upper part of the body. The front end of the upper holder is bent downward, and an installation hole(21) is formed in the front end. A passage to flow coolant is formed adjacent to the installation hole. The first welding protruding part is connected to the installation hole of the upper holder. The lower holder is connected to the lower part of the body, and has a passage to pass coolant. The second welding protruding part is connected to the front end of the lower holder.
