Precision digital control for reliable welding The Spot Welder Machine Time Control Board features a digital display and encoderbased adjustment, delivering more accurate and stable control with a longer service life than traditional potentiometers. Foot pedal with anti shake function The foot pedal design ensures each press completes a welding cycle, reducing the risk of miswelds caused by poor switch contacts or other factors. Flexible multifunction control Offers adjustable single and double weld settings, welding count, synchronous triggering, and poweroff saving. The 41A thyristor version can control a transformer below 1000W. AC transformer powered, not compatible with DC Requires an AC transformer powered supply in the 12V–17V range; DC power supplies are not supported. Practical use scenarios 1) Building or repairing battery packs and tab welds where repeatable, controlled welds are essential. 2) Small electronics assembly or micro metal bonding that benefits from adjustable weld counts and synchronous triggering for consistent results. 3) Hobbyist or light industrial sheet metal work requiring reliable one or twostep welds with energysaving operation. Compatibility and performance notes Designed to work with appropriate AC transformers (12V–17V). The board is available in a 41A thyristor version suitable for transformers under 1000W, offering strong performance in compact spotwelding applications.
