Claims

[Claims for Utility Model Registration] By arranging an upper electrode and a lower electrode one above the other so that they can move relatively apart, and bringing each electrode into contact with two pieces of workpieces to be welded, the workpieces can be mutually connected. In a resistance welding machine for welding, a plurality of fitting parts are formed on the same circumference that corresponds vertically to the upper electrode on a sliding ring body that fits around the rotating main shaft disposed at the bottom of the welding position, A resistance welding machine characterized in that lower electrodes are removably fixed to each fitting part.
