ABSTRACT:
A combined pivot joint and electric contact device between two welding current conductors forming part of the welding circuit of a resistance welder. The device is provided with a pair of contact plates extending at right angles to the joint axis and connected each to one of the welding current conductors. The plates are rotatable and axially displaceable with respect to each other. A yieldable thrust member urges the plates into engagement with each other. A channel provided in at least one of the plates has an outlet in the contact face of the plate and an inlet away from said face. Separation of the plates is effected by connecting the channel to a source of compressed gas to discharge a current of gas through the port.
