Assembly line technicians rely on the Duplomatic electric coil to keep the indexing turret of spot‑welding stations moving without interruption, delivering a steady power feed that lets the robot swing between weld points at high speed. The coil is mounted on the turret’s power bus and provides the necessary electromagnetic force to drive the rotation motor each time a new welding head is positioned. By supplying reliable energy during each indexing cycle, the coil helps maintain cycle times that match the line’s production rhythm, preventing bottlenecks in the body‑in‑white stage. When the same coil is used in a robotic paint applicator, it powers the turret that rotates the spray nozzle, allowing rapid colour changes and precise overlap control. In both cases the component acts as the heart of the turret’s motion system, turning electrical input into smooth mechanical motion so that operators can keep the production line running at the required throughput.
