Overview
The Sunstone CD Dual-Pulse Advanced (DPA) Series represents the most advanced capacitive discharge welding platform in the Sunstone lineup. Built specifically for automation-driven environments, DPA models combine Sunstone’s proven dual-pulse welding technology with an upgraded digital interface that allows precise control over weld energy, pulse sequencing, and timing.
Unlike standard or RS models, the DPA Series is engineered for repeatability, traceability, and integration—making it ideal for robotic cells, PLC-controlled systems, and high-precision production workflows. These systems deliver consistent, high-quality welds across demanding applications where process control and reliability are critical.
