Key benefits Precise time control for repeatable welds: the digital display and readingenabled control board provide accurate encoder adjustments, delivering stable performance and longer life than traditional potentiometerbased controls. Flexible, multifunction operation: supports adjustable single and double welding settings, weld counting, synchronous triggering, and poweroff saving, giving you versatile control for various tasks. Reliable weld cycles with antishake foot pedal: the foot pedal antishaking feature ensures each press completes a full welding cycle, reducing the risk of miswelds caused by switch contact issues or other factors. Safe and compatible power supply: designed to be powered by an AC transformer in the 12V–17V range; not compatible with DC power supplies, ensuring proper operation and safety. What it offers Precision Double Controller: Spot Welder Machine Time Control Board features a digital display for easy reading, more accurate encoder adjustment, and a longer service life compared with traditional potentiometers. Multi function: The Spot Welder Control Board supports adjustable single and double welding settings, welding count, synchronous triggering, and poweroff saving. The 41A thyristor version can control transformers below 1000W. Foot pedal anti shaking function: The Spot Welding Equipment is equipped with a foot pedal antishaking function to ensure that every press completes a welding cycle, preventing miswelds due to poor switch contacts or other factors. AC transformer requirements: The Transformer Control Board must be powered by an AC transformer (12V–17V) and is not compatible with DC power supplies. Compatibility and power requirements Compatible with AC transformers in the 12V to 17V range for reliable operation. Not compatible with DC power supplies. The 41A thyristor version supports control of transformers below 1000W. Use scenarios Hobby and small workshop welding: ideal for precise, repeatable spot welds on metal parts using a transformer under 1000W, with easy timing control and repeatable cycles. Smallscale production or tasks: suitable for operations that require consistent weld counts and synchronization between welding pulses, improving throughput and uniformity. Assembly or with foot pedal control: enables hands operation and stable cycles in scenarios where continuous or timed welding is needed, such as electronics enclosures, metal brackets, or chassis assemblies. Notes For results, power the system with a suitable AC transformer within the specified voltage range (12V–17V). The board provides enhanced control accuracy and longer component life compared with traditional potentiometerbased systems, delivering dependable performance in everyday spot welding tasks.
