  • Patent number: 4018976
    Abstract: This kickless water-cooled resistance welding cable consists of an elongated elastomeric hose containing two pairs of stranded copper wire conductors or "ropes" of opposite alternating polarities mounted in the four peripheral grooves of an elongated elastomeric separator of cruciform cross-section with a central cooling water passageway therethrough. These grooves are of circular cross-section such that when the separator is twisted longitudinally the groove side walls compress and tightly grip the conductors while these are cooled by water flowing into the grooves through perforations from the passageway. The conductors are connected at their opposite ends to copper terminals, each of which includes a pair of elongated semi-cylindrical copper terminal halves with an insulating strip between them and with two pairs of circumferentially-spaced bosses containing cable conductor sockets arranged in alternating polarity.
