Sunstone High Power - Micro Resistance - Advanced CD Spot Welder
The CDDP-A 1200 Fine-Spot Capacitive Discharge Welder is Sunstone’s most advanced precision welding system, engineered for professionals who need clean, strong, and highly repeatable welds on small or delicate metal components. Whether you’re assembling battery packs, joining micro-wires, working with copper alloys, or producing high-tech prototypes, the CDDP-A delivers ultra-fast energy release, reliable performance, and pinpoint accuracy typically found only in specialized industrial welding systems.
At the core of the CDDP-A is a powerful 1200-watt-second capacitive discharge engine that produces consistent weld energy unaffected by line-voltage fluctuations. The rapid energy delivery creates a very small heat-affected zone, making it ideal for thin metals, conductive materials, and precision assemblies. Dual-pulse functionality enhances results by cleaning surface inconsistencies with the first pulse and forming a strong, clean weld with the second—ensuring repeatability in demanding production environments.
A modern touchscreen interface gives users full control with waveform visualization, data logging, SPC tools, and Wi-Fi connectivity. Operators can save settings, monitor performance, export data, and update firmware directly from the interface. Compact, low-maintenance, and engineered for accuracy, the CDDP-A 1200 is built for labs, small manufacturing facilities, R&D departments, and any application requiring high-quality micro-resistance welds.
