Abstract: Disclosed are weld electrode plugs with polymeric inserts for loss-of-cooling detection, methods for making or for using such weld electrode plugs, and electric welding systems equipped with loss-of-cooling detection plugs. A disclosed loss-of-cooling detection assembly includes a plug that attaches to the weld shank of a welding system such that the plug fluidly couples to a coolant bore within the shank. The plug includes a plug body with a clearance hole extending therethrough. An insert detachably mounts to the plug such that the insert fluidly seals the clearance hole. This insert is fabricated from a polymeric material, such as a shape memory polymer, that alters a physical property, such as shape/size, of the insert responsive to changes in temperature and/or pressure of coolant fluid in the shank's bore. When this physical property is altered, the insert unseals the clearance hole causing a detectable leak of fluid from the shank.

Abstract: A tool for providing an electrical interface between a motor circuit analyzer having a plurality of motor circuit analyzer connection ports and an electrically operated machine having electrical devices and a multi-conductor cable comprising electrical wires connected to the electrical devices. The tool includes a plurality of tool connection ports configured to be electrically connected to motor circuit analyzer connection ports. The tool also includes a plurality of terminals configured to be electrically connected to the conductors of the multi-conductor cable, and a switching section configured to selectively electrically connect two of the plurality of tool connection ports to two of the plurality of terminals.
