Designed to work seamlessly with a 100A SCR welding circuit, this control board includes a digital display that shows time settings and current levels in real time. Crossing detection technology enables accurate phase shifting of the thyristor, delivering stable and efficient welding performance. Optocoupler isolation provides safe separation between power and control circuits, enhancing user safety during operation. Screwless quick connection terminals for the power cord and foot switch allow hassle setup and reliable connections. Benefits at a glance: Realtime monitoring of current and timing for precise control Consistent weld quality through accurate thyristor phase control Safer operation with electrical isolation between control and power circuits Easy installation with tool, quickconnect terminals Practical applications: Automotive or sheet metal welding tasks requiring stable current and repeatable results Workshop setups that use a foot switch for hands operation Upgrading or retrofitting existing SCR based welding systems to improve control and reliability
