Digital control compatibility This control board is designed for 100A SCR spot welding systems. The digital interface clearly displays time settings and current levels, enabling easy monitoring and repeatable weld cycles. Accurate phase shifting technology Features a robust crossing detection circuit that guarantees reliable thyristor phase shifting, contributing to stable welding performance and consistent weld quality. Safety through isolation Strong and weak currents are separated by optocouplers, providing safe operation and protecting control circuitry during welding projects. Quick connection systems The power cord and foot switch use screwless quickconnect terminals for fast, tool assembly and dependable connectivity. Applications In metal fabrication shops using 100A SCR based spot welders, for welding sheet metal components such as automotive panels or chassis parts where precise timing and current control matter. In battery pack production or , where consistent weld cycles and safe isolation improve quality. In maintenance or workshop settings, to reduce setup time and ensure reliable connections for welding systems.
