PURPOSE: A slip ring of a cable reel for a gas welding machine is provided to improve use efficiency through a gas evaporation by cooling the conduction and friction heat due to the slip rotation of a fixed ring and a rotary ring with gas. CONSTITUTION: A fixing ring(10) forms an installation hole(11) in the center thereof. The fixing ring includes a connection screw hole(15) which connects a gas supply pipe. A rotary ring(20) has an installation hole(21) in the center thereof. The rotary ring includes a connection screw hole which connects an assembly groove and a gas supply pipe. Ring type concave parts(17,18) are formed on the left and right sides of a ring type recess(16) in the inner surface of the rotary ring. |
