  • Patent number: 5266768
    Abstract: A system and method for cooling multiple weld tips of a welder. The welding system includes a housing and a plurality of weld tip plungers, each plunger being independently movable with respect to the housing, and each plunger having a mechanism for receiving a weld tip, a first port and a second port. The system also includes a primary input manifold including a mechanism for receiving fluid and at least one outlet port and a primary output manifold including a mechanism for discharging fluid and at least one inlet port. A first hose or hoses for communicating fluid from the at least one outlet port of the primary input manifold to each of the first ports of the plungers and a second hose or hoses for communicating fluid from each of the second ports of the plungers and to the at least one inlet port of the primary output manifold also are included in the system such that a fluid passing between the first and second ports of each plunger may circulate through a weld tip connected to the plunger.
