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. Fluid is provided to the at least one outlet port of the primary input manifold such that fluid flows through the first hose(s), through the first port of each weld tip plunger, through each weld tip, through the second port of each weld tip plunger and through the second hose(s) to the at least one inlet port of the primary output manifold. The system and method allows each weld tip of a multi-tip welder to be cooled individually and does not utilize seals which may deteriorate and subsequently case damage to the weld tips.
