Abstract
A welding conductor having a curved stack of flexible copper leaves which have an inside curved surface. Resilient metal shims bear against the inside surface to urge opposite ends of the stack outwardly. The outer end of the stack is connected, for example, by welding, to an outer plate which carries an outer copper shoe. The inner end of the stack is welded to an inner plate. A fire-resistant ceramic cloth surrounds the stack to protect the metal leaves.
