Multi function control: Spot Welder Control Board offers adjustable single and double welding modes, welding count, synchronous triggering, and poweroff saving. Benefit: supports different weld tasks with energy efficiency and reliable operation. The 41A thyristor version can drive a transformer below 1000W for compatible applications. Precision double controller: Spot Welder Machine Time Control Board features a digital display with clear readout and precise encoderbased adjustments. Benefit: more accurate, stable timing, and noticeably longer service life than traditional potentiometers. Enhanced design and easy installation: The control board uses a doublesided welding design with optimized component layout, which facilitates easier installation inside the machine housing. Benefit: quicker setup, tidier integration, and reliable performance in compact spaces. Foot pedal anti shaking function: The foot pedal is designed to prevent miswelding by ensuring each press completes a welding cycle, even if switch contacts or other factors vary. Benefit: consistent weld quality and reduced rework. Use scenarios DIY battery pack assembly and electronics projects: Use adjustable weld modes and precise timing to create uniform welds on battery tabs or metal connectors, with energysaving operation. Smallscale fabrication and electronics assembly: Ideal for welding thin metal sheets or tabs in electronics, copper or aluminum components, or hobby/ projects requiring repeatable, reliable cycles. Workshop retrofitting and service applications: Upgrade or retrofit existing spot welders with a digital timing display and robust control, enabling easier installation in existing machine housings and improving reliability for ongoing production or work.
