  • Patent number: 4676562
    Abstract: An electrical connector for use in arc welding comprises a magnet of generally toroidal shape housed in a cup-shaped support and secured by a screw to a casing having a surrounding annular face substantially coplanar with the end face of the magnet and the rim of the cup-shaped support. The magnet is made from a material incorporating a high proportion of cobalt having a low temperature coefficient, which is resistant to high temperatures and substantially unaffected by the high welding current which flows therethrough in operation.
