Motor-driven tip dressers are used in conjunction with robotic resistance welders in a manufacturing area like an automobile body assembly plant. Essentially they are like large pencil sharpeners and they require regular maintenance. After maintenance the dressers are not always switched back on, so that when the robotic welder requests tip sharpening, the tips are not dressed and poor quality welds result, which in turn produces poor quality panels. By installing an NK Technologies’ Current Operated Switch on the tip dresser the status is signaled and an alarm is generated to warn if the dresser remains un-powered and offline. NK’s unique split-core packaging is ideal for retrofit installation and the compact solid-core unit is well suited for OEM applications.
