An example welding cable connector system comprises: a male connector comprising a first conductive body for conveying welding power, a first sealed passageway disposed coaxially of the first conductive body for conveying shielding gas, and a first preassembled valve assembly coupled to threads within the first sealed passageway and configured to stop flow of the shielding gas when the male connector is not engaged; and a female connector comprising a second conductive body for conveying the welding power, a second sealed passageway disposed coaxially of the conductive body for conveying the shielding gas, and a second preassembled valve assembly coupled to threads within the second sealed passageway and configured to stop the flow of the shielding gas when the female connector is not engaged.

Embodiments of the present disclosure include a cable management system with a housing comprising a first shell and a second shell configured to couple together about welding system cabling such that a portion of the welding system cabling is contained by the housing. The first and second shells form openings at ends of the housing such that the welding system cabling is capable of extending through the openings and such that edges of the openings enclose a perimeter of the welding system cabling when the first and second shells are coupled together about the welding system cabling. A cradle receives a weld cable of the welding system cabling. A cable clamp engages the weld cable and cooperates with the cradle to restrict movement of the weld cable when the weld cable is disposed in the cradle and the cable clamp is engaged.

An electric arc torch includes a torch base, and a cooling conduit having a conduit wall forming a central axial bore and having a plurality of longitudinal cooling channels spaced circumferentially around the bore. The cooling channels extend through the conduit wall from a first end portion to a second end portion of the conduit. The cooling channels include both a plurality of cooling liquid distribution channels and a plurality of cooling liquid return channels alternately arranged within the conduit wall. The conduit includes a circumferential cooling liquid manifold in fluid communication with each of the cooling liquid distribution channels, a circumferential return manifold in fluid communication with each of the cooling liquid return channels, and a circumferential recirculation manifold in fluid communication with each of the cooling liquid distribution and return channels such that the cooling liquid distribution and return channels are in fluid communication through the circumferential recirculation manifold.

A connector for connecting together a welding torch power cable including a threaded connector, a coolant line and a shielding gas line to a welding power and/or coolant source including a connector receptacle includes an electrically conductive tubular body having a front end and a back end. The tubular body front end is adapted to receive and connect to the power cable threaded connector. The tubular body back end is adapted to connect to the connector receptacle. The tubular body also includes a passageway therein to communicate shielding gas or coolant between the source and the torch. A hose connector is attached at an end of the passageway. A casing including a longitudinally extending tubular side wall terminates in front and back ends. A twist cap is releasably connectable to the back end of the casing. A cable cover adapter is releasably connectable to the front end of the casing.

Provided is a wire body processing structure for a robot having a wrist, a base end of which is connected to a forearm in a rotatable manner about a first axis and a distal end of which has a plurality of working tools attached thereto. The wire body processing structure includes a first flexible conduit disposed along the first axis from the forearm to the distal end of the wrist and also includes a second flexible conduit disposed longitudinally within the first conduit. A first wire body for one of the working tools is extended longitudinally through the second conduit. A second wire body for another one of the working tools is extended longitudinally through a space between the first conduit and the second conduit.

An electrical connector is disclosed. The electrical connector includes a multi-diameter power pin having a proximal portion having a first diameter; an engagement portion having a second diameter smaller than the first diameter; a bearing portion having a third diameter smaller than the second diameter; and a threaded distal portion having a fourth diameter smaller than the third diameter. A receiving block having a multi-diameter through hole is configured to receive the multi-diameter power pin. The receiving block includes a plurality of gaps extending radially from the multi-diameter through hole to an outer surface of the receiving block, a receiving portion disposed between a lateral surface of the receiving block and a first gap of the plurality of gaps; and a clamping portion disposed between the plurality of gaps.

An adjustable cable fitting for a thru-arm cable of a robotic welding torch includes a female member formed of an elongated tubular body having a forward end, a rear end, and a through hole extending axially from the forward end to the rear end. The forward end includes a nose portion for connection to a welding cable. A male member is cooperable with the female member in a telescoping manner. The male member includes a shaft received in the through hole of the female member, a receiver connected to the shaft for receiving a power pin, and a through hole extending axially through the shaft and receiver. A nut is disposed on the shaft for locking a position of the shaft relative to the female member. Adjustment of a disposition of the male member relative to the female member varies an effective length of the power cable.

A spool gun having a very unique look, due to its arrangement of internal and external features. The spool gun has its wire spool compartment located below the handle and the user's hand, when the user is gripping the spool gun in an operational position, thus providing a wire path through the handle to the body of the spool gear wherein the wire feed mechanism is located. The wire feed mechanism includes a 90-degree drive system, which can include a worm gear. A gas/power cable is connected to the body of the spool gun forward of the handle.

An aspect of the present disclosure provides a welding torch that includes a torch head and a torch body removably connected to the torch head. The torch head includes first and second torch-head flow paths for flowing cooling water, first and second inlets/outlets communicating with the first and second torch-head flow paths, respectively, and a movable part movable in an axial direction of the torch head. The torch body includes a torch-body flow path for flowing cooling water, and first and second connection ports communicating with opposite ends of the torch-body flow path, respectively. The first and second inlets/outlets communicate with the first and second connection ports, respectively, when the torch head and the torch body are connected to each other. The first and second inlets/outlets are closed with the movable part when the torch head and the torch body are separated.
