Introducing SUNKE: Revolutionizing Welding with Capacitive Discharge Technology
Release Time：
2025-07-25
At SUNKE, we are excited to introduce our reliable brand and our range of innovative welding solutions, particularly our capacitive discharge welders (CD welders). These advanced machines are designed to provide exceptional precision and efficiency in various welding applications. By leveraging trusted technology, we ensure that our products meet the highest standards of performance and reliability.
What is Stored Energy Welding
Stored energy welding is a technique that utilizes capacitors to store electrical energy before discharging it to the workpiece. Our capacitive discharge welders harness this concept through advanced electronic voltage elevation and constant-current charging circuits. By doing so, we can store electrical energy effectively and discharge it instantaneously during the welding process. This method allows us to reach welding currents that can range from tens to hundreds of thousands of amperes in a remarkably short period. The result? Minimal heat loss and flawless welds, perfect for high-precision applications.
Key Features of Our Capacitive Discharge Welders
Our capacitive discharge welders come equipped with a variety of features that enhance their efficiency and usability. One of the standout specifications is the input voltage capability, which ranges from 3-phase AC 110V to 480V ±10%. This versatility ensures that our welders can be used in various industrial settings without compatibility issues. Moreover, our welders offer an output voltage range of 15–400Hz with PWM up to 1000V. This flexibility allows operators to adjust settings according to specific welding requirements. Additionally, our machines boast a duty cycle (ED) of 10%, meaning they can handle demanding tasks without overheating. With energy options available in 10, 20, 30, and 40 KJ, our systems cater to diverse welding needs.
Efficiency Through Advanced Cooling and Control Methods
To maximize performance, our capacitive discharge welders feature a water-cooled system that minimizes thermal buildup during operation. This cooling method is crucial for maintaining optimal performance, especially during extended welding sessions. Control is another significant aspect of our welders. We offer various control methods, including KSR, KUR, PHA, and SAIRS, which provide operators with the flexibility to choose the best approach for their specific applications. Furthermore, our solenoid valve control operates at 24 volts, while the proportional valve control can handle signals from 0–10V, 4–20mA, and 0–20mA. These advancements ensure precise control over the welding process, leading to consistent and high-quality results.
Conclusion
In conclusion, our brand SUNKE is proud to introduce a line of capacitive discharge welder that utilize stored energy welding technology to deliver superior performance. With features designed for precision, efficiency, and reliability, we are confident that our welders will meet your needs in the fast-paced world of modern manufacturing.
