Patent attributes
A welding cable connector system having a male connector and a female connector. The male connector includes a first conductive body for conveying welding power. The male connector also includes a first sealed passageway disposed coaxially of the first conductive body for conveying shielding gas, and a first Schrader valve configured to stop flow of shielding gas when the male connector is not engaged. The female connector includes a second conductive body for conveying welding power. The female connector also includes a second sealed passageway disposed coaxially of the conductive body for conveying shielding gas, and a second Schrader valve configured to stop flow of shielding gas when the female connector is not engaged. The male and female connectors are mutually engageable to conduct welding power and shielding gas therethrough. The first and second Schrader valves seal the flow of shielding gas when the connectors are not mutually engaged.
