Sunstone Micro Resistance - Advanced Dual Pulse CD Spot Welder
The Sunstone CDDP-A series to any business that needs high-precision, industrial-grade micro-resistance welding. This machine stands out because it combines raw welding power with intelligent monitoring and automation features that dramatically improve workflow speed, weld consistency, and long-term production reliability.
The CDDP-A uses Sunstone’s next-generation dual-pulse capacitive discharge technology, which allows the welder to deliver fast, clean energy bursts ideal for highly conductive materials such as copper, aluminum, and brass. The first pulse prepares the material by removing surface inconsistencies, while the second creates a strong, stable bond—reducing splatter, electrode wear, and material waste.
What truly sets the CDDP-A apart is its built-in intelligence. With real-time weld monitoring (current, voltage, and power), statistical process data, waveform visualization, and auto-generated weld quality alerts, the machine gives operators complete control over consistency and quality. Whether you're building battery packs, welding sensors, working with fine mesh, or manufacturing components that require hundreds or thousands of welds per day, the CDDP-A is engineered for accuracy, repeatability, and smooth integration into both manual and fully automated production lines.
Its intuitive touch-screen interface, cloning feature, Wi-Fi, built-in videos, and full PLC connectivity make setup and training incredibly simple—even across multiple machines. From small workshops to high-volume production, the CDDP-A is built to deliver long-term performance with low maintenance and high reliability.
