Abstract:
1. A welding cable connector system comprising: a first connector comprising a first conductive body configured to convey welding power, a first sealed passageway disposed coaxially of the first conductive body configured to convey shielding gas, and a first gas sealing valve configured to seat to stop flow of shielding gas when the first connector is not engaged; a second connector comprising a second conductive body configured to convey welding power, a second sealed passageway disposed coaxially of the conductive body configured to convey shielding gas, and a second gas sealing valve configured to seat to stop flow of shielding gas when the second connector is not engaged; and a welding cable coupled to the first connector at one end of the welding cable and to the second connector at an opposite end of the welding cable configured to convey welding power and shielding gas through the welding cable, wherein the first connector is configured to seal against the second connector via a tapered seating surface, and wherein the first connector comprises a first set of keyed threads, the second connector comprises a second set of keyed threads, and the first and second sets of keyed threads are configured to engage with one another via a quarter-turn to couple the first and second connectors together.
