Core features Spot Welder Control Board offers adjustable single and double weld modes, welding count control, synchronous triggering, and power off saving for improved welding reliability and energy efficiency. 41A thyristor version provides control of transformers below 1000W, suitable for compact setups. Spot Welder Machine Time Control Board includes a digital display, precise encoder adjustments, and longer service life compared to traditional potentiometers. Spot Welding Machine Control Board adopts double sided welding and optimized component layout to simplify installation in the machine housing. Transformer Control Board must be powered by an AC transformer within 12V17V and is not compatible with DC power supplies. Compatibility and requirements Power: AC transformer 12V17V required. Do not use DC power supplies. The 41A thyristor variant is designed to control transformers under 1000W. Designed for integration into spot welding applications with standard 1217V AC input provisions. Use scenarios Prototyping and smallscale production: Use adjustable single and double weld settings and welding count to create repeatable welds on thin metal parts with consistent quality, supported by synchronous triggering for timing precision. Battery tab and thin sheet assembly: Employ the 41A thyristor version to drive transformers under 1000W for compact, reliable spot welding in battery packs or electronics assemblies, with a digital display for quick setup verification. Custom welding stations and enclosures: Install the control board inside a machine housing using its enhanced design and layout for a cleaner, easiertowire compact welding solution that reduces setup time.
