ABSTRACT:
A power block adapted to couple a water-cooled power cable of a welding torch or the like to a power source and a water conduit. The power block comprises an electrically conductive housing which defines an aperture for receiving a post of a power supply, and a pair of angularly disposed cylindrical ports for receiving and retaining a water conduit and a water-cooled power cable. By virtue of the angular relationship between such ports, there is minimal stress on the water-containing sleeves of the water conduit and power cable, and lower torque about the power post tending to loosen the power block from engagement with the post. Preferably, the power block housing defines a third port having a quick-connect/disconnect feature for receiving and retaining a second power cable.
