  • Dual power pin connector assembly for a MIG welding machine
    Patent number: 9296058
    Abstract: A dual power pin connector assembly for connecting both a MIG welding gun and a spoolgun to a welding machine. The dual power pin connector is comprised of a busbar portion that electrically and mechanically couples the positive output terminal of the welding machine power supply to a wire drive for the MIG welding gun. The connector is further comprised of an integral quick release assembly/clamping portion that electrically and mechanically connects the positive power supply terminal to a power supply cable for the spoolgun. The clamping portion receives and retains a power pin coupled to one end of the spoolgun power cable in a receptacle that is manually tightened and loosened.
