Sunstone Micro Resistance - Dual Pulse CD Spot Welders
If your operations demand clean, consistent, and high-strength spot welds, the Sunstone Dual Pulse CD Welders are one of the smartest investments you can make. As a reseller, I confidently recommend these welders to manufacturers, technicians, and industrial shops looking for dependable power with superior weld control.
The CDDP Series—available in 200Ws, 400Ws, and 600Ws models—delivers a significantly higher energy output compared to standard CD welders. The dual-pulse system improves weld quality by removing contamination on the first pulse and applying the main weld energy on the second. The result? Stronger, cleaner, and more repeatable welds across a wide range of materials.
With fast recharge rates and an intuitive interface, these machines are a perfect fit for applications like battery pack assembly, thermocouple welding, copper and aluminum connections, honeycomb tacking, and more. Whether you're in electronics, automotive, aerospace components, or precision manufacturing, the CDDP welders provide reliability without the steep cost of large industrial welding systems.
Designed with performance and affordability in mind, these welders offer both beginners and advanced users a tool that delivers production-grade results with minimal setup.
