Spot Welding Machine Control Board Key benefits Easy installation: enhanced design with double sided welding and optimized component layout makes it straightforward to mount inside a machine housing. Precise control you can trust: a precision double controller with a digital display and encoder adjustments delivers more accurate, stable tuning and longer service life than traditional potentiometers. Flexible, multi function operation: supports adjustable single and double welding settings, welding count, synchronous triggering, and a poweroff saving function to optimize energy use and extend component life. Power for small to mid sized work: the 41A thyristor version can control a transformer below 1000W, suitable for common spot welding tasks. Clear power requirements: must be powered by an AC transformer in the 12V–17V range and is not compatible with DC power supplies. Key features and capabilities Enhanced design for installation: double sided welding and optimized component layout enable a compact, reliable fit within standard machine housings. Digital display and encoder control: readouts provide clear status information; encoder adjustments offer precise and durable tuning compared with traditional potentiometers. Multi function control: enables selectable single or double weld settings, welding count control, synchronous triggering, and a poweroff saving function to reduce unnecessary energy use. Thyristor performance option: the 41A version provides control for transformers below 1000W, expanding suitability for common spot welding setups. Compatibility and power requirements: designed to operate with an AC transformer supplying 12V–17V AC; not compatible with DC power supplies. Physical considerations: compact and robust design intended for integration into typical welding systems and housings. Application scenarios Battery pack fabrication and : use single or double weld modes with controlled welding counts and synchronized triggering to produce consistent tab welds on battery packs while preserving cell integrity. Electronics and small metal tab welding: perform precise spot welds on copper or nickel tabs for smallscale electronics assemblies or prototypes, with repeatable results and energysaving operation. Service and maintenance tasks: apply preset welding sequences to routine repairs or rebuilds, leveraging the poweroff saving function to minimize wear during off states and retain stable settings for quick reuse. Compatibility and power details Input power: AC transformer required; 12V–17V range. Incompatibility: not suitable for DC power supplies. Transformer capacity: 41A thyristor version supports transformers below 1000W.
