    Abstract: A first electrode coolant path is configured to cool a first welding electrode by liquid coolant flowing from a supply path through the first electrode coolant path to a return path. A second electrode coolant path is configured to cool a second welding electrode by liquid coolant flowing from the supply path through the second electrode coolant path to the return path. Three or more valves are configured to stop or reduce liquid coolant flow through the first or second electrode coolant path and configured to stop or reduce liquid coolant backflow from the return path when the first or second welding electrode is at least partially detached. At least one valve is coupled in the first or second electrode coolant path. A drawback apparatus generates a suction force to draw liquid coolant away from a gap formed when the first or second welding electrode is at least partially detached.

    Abstract: An improved cooling system for adapting to a two-component welding electrode device having a shank and cap, includes a retractable nozzle tube, a manifold, and an adjustment element for adjustably interconnecting the tube and manifold. A threaded bushing or plunger is attached to the tube and operable to adjust the distance between the interior surface of the cap and the outlet of the tube to a preferred distance. A threaded sleeve interconnects the tube and bushing for additional adjustability. The tube defines an elastically compressible bellows section, and a spacer is removably attached to the distal end of the tube for automatic adjustment of the outlet position by the cap.

    Abstract: The present invention relates to an improved resistance weld-based gun assembly for use in an electric welding system without a need for plant-provided air and water-cooling circulation systems. In one aspect of the invention, a resistance-based force controller measures the resistance of a secondary circuit of the weld gun, the combined resistance of the secondary circuit in parallel with the circuit formed by the workpieces and opposing electrodes when sandwiched between the electrodes, and calculates the resistance of the workpieces. The measured resistance is compared to a predetermined resistance and the sandwiching force of the electrodes incrementally adjusted until the resistance of the workpieces is acceptable. The invention also relates to a closed loop coolant system having a coolant line, a coolant contained within the coolant line, a heat exchanger, and a mechanical coolant pump. One possible pump comprises an elastic bladder dependent upon the state change of the coolant. A second possible pump comprises a reciprocating extractor mechanically connected to the weld gun actuator. In yet another aspect of the invention, the welding system relies solely on electrode arm material for heat dissipation, the heat being conducted through the electrode arm material to an outer surface of the arm where the heat is dissipated through natural convection. To promote natural convection, a plurality of ribs with channels defined therebetween or openings extending through the arm itself increase the surface area and the rate of convection.

    Abstract: In an automated welding machine, where a flow of liquid coolant is supplied to welding components on the machine from a source of coolant and then returned to the source of coolant, a safety system is provided that shuts down the flow of coolant in the event of a fault. Faults are detected by a supply sensor and a return sensor for measuring the flow rates of coolant in the supply and return lines. A microprocessor is adapted to compare the supply flow rate and return flow rate and detect differences between the two rates. The difference between the detected rates as compared to a leak threshold value, and the microprocessor is adapted to generate a valve shutoff signal in the event the detected difference in flow rates exceeds the leak threshold value. A value in the supply coolant line is responsive to the valve shutoff signal to shutoff flow of coolant in response thereto.

    Abstract: A rotary joint for transferring high amperage electrical energy between a stationary member and a rotary member and particularly relates to a coupling member fixedly carried by the fixed member and having brushes engaged with an internal cylindrical surface on the rotary member. A principal feature of the rotary joint is that the brushes are permanently, yet flexedly, connected to a stationary hub of the coupling member, whereby the only relative moving surfaces are those of the brushes and the internal cylindrical surface and wherein any misalignment or eccentricity between the rotating member and the coupling member is readily accommodated for by the shifting of the brushes.
