The invention discloses a conductive apparatus for an arc welding rotation position. The conductive apparatus comprises a carbon brush block, a carbon brush mounting box, nuts, connecting rods, insulating gaskets A, insulating gaskets B, insulating shaft sleeves, a connecting plate, oil-free bushings, springs, connecting shafts, a box body, jackscrews and shaft check rings, wherein the connecting rods are fixedly connected with the rotary box body through the nuts; the connecting rods are connected with the connecting plate through the insulating gaskets A, the insulating gaskets B and the insulating shaft sleeves; the lower end of each connecting shaft is connected with the connecting plate through the corresponding oil-free bushing; the upper end of each connecting shaft is connected with a carbon brush connecting base parallel to the connecting plate through the corresponding jackscrew; each spring is arranged on the corresponding connecting shaft between the carbon brush connecting base and the oil-free bushing in a sleeving manner; and a rotary shaft is mounted on the upper surface of the carbon brush connecting base through a bearing pedestal. By adoption of the conductive apparatus for the arc welding rotation position, the carbon brush block has the up-down floating function by virtue of the spring apparatus on the connecting shafts, so that the conductive apparatus is particularly suitable for a mechanism with inconvenience in manpower carbon brush block switching.
