S. S. Controls offers Resistance Spot Welding Controller with Constant Current Feedback. S. S. Controls manufactures and exports high performance welding control equipment that are used to control the parameters like time, voltage and current and allows accurate and consistently repeatable performance of the welding machines. The company manufactures precision electronic controllers for any kind of resistance welding application. The Resistance Spot Welding Controller with Constant Current Feedback has Secondary Current Feedback for Constant Weld Current Output. The Resistance Spot Welding Controller eliminates Variation in weld output because of transformer losses. The Resistance Spot Welding Controller with Constant Current Feedback has Current feedback with the help of easy to mount toroidal current sensing coil. The Resistance Spot Welding Controller comes with user selectable spot or seam mode, Error detection for transformer over heat or thyristor over heat or pressure, water flow etc.
