PURPOSE:To miniaturize an equipment and to improve the efficiency in welding by providing an upper part welding gun approachable and separatable to and from the lower part welding gun of fixed position and arranging the spacer feeding device equipped with a blank cutting means and spacer chuck. CONSTITUTION:Lower part welding guns 13, 13A are provided respectively on the lower gun supporting members 11, 11A at the lower part of a fixed frame 2 and moving frame 3 and the upper welding guns 21, 21A approachable to and separatable from the lower guns 13, 13A are arranged as well on upper arms 17, 17A. In the case of the gap and width of the upper and lower wire gauzes being changed, the moving frame 3 is moved by the changed part and simultaneously the lift part of a spacer feeding device 68 is moved and a wire gauze is fed by a spacer chuck to effect welding. Since the reinforcement cage of different dimension can be manufactured with one unit of a wire gauze spacer welding equipment 1, the equipment is miniaturized and the welding efficiency is improved with the improvement in the spacer feeding efficiency.
