JCT Launches Breakthrough 6000W Water-Cooled Handheld Fiber Laser Welder
*[Jinan, China, July 31]** – Marking a major breakthrough in the field of handheld industrial metal welding, we are proud to announce the official launch of the highly anticipated water-cooled JCT-WU-6000W handheld fiber laser welding machine. Designed to simultaneously meet the demands of heavy-duty industrial welding and provide the flexibility of manual operation, the JCT-WU-6000W is the result of 18 months of intensive R&D and rigorous field testing across three continents.
For many years, the handheld laser welding market has been dominated by water-cooled 1,500W, 2,000W, and 3,000W systems. While these lower-power devices perform exceptionally well when welding thin stainless steel and aluminum sheets, they fall short of meeting the demands of heavy-duty applications such as shipbuilding, steel structure fabrication, and thick-plate processing. For steel plates thicker than 10 millimeters, traditional MIG (Metal Inert Gas) welding has long been the only viable option, despite its well-known drawbacks, such as excessive heat input, severe thermal distortion, and the need for extensive post-weld grinding. The launch of the JCT-WU-6000 series has completely transformed this landscape.
Breaking Through Thickness Limitations
The core breakthrough of the JCT-WU-6000 series lies in its use of a cutting-edge 6,000W continuous-wave (CW) Raycus fiber laser, which was jointly developed through a strategic partnership with a world-leading manufacturer of optical components. This unprecedented power density enables operators to achieve single-pass full-penetration welding on carbon steel up to 10 mm thick and aluminum alloys up to 8 mm thick.
“Customers in the heavy equipment industry had clearly expressed their dissatisfaction,” our chief engineer noted. “They loved the speed and smooth weld bead surface of our 6,000W [handheld laser welder], but they wanted to achieve exactly the same performance when welding structural components. The JCT-WU-6,000W is our definitive answer. “We are no longer just replacing TIG welding; we are actively replacing heavy-duty MIG welding.”
Technological Innovations in the JCT-WU-6000W
Increasing the power of a handheld laser to 6,000W presents significant thermal management and optical challenges. To ensure the device can operate around the clock in harsh industrial environments without overheating or component degradation, our engineering team has introduced several patented technological innovations:
1. Dual-Circuit Intelligent Active Cooling System:
The 6,000W Raycus laser generates a significant amount of heat. The WU-6000 integrates a more sophisticated dual-circuit industrial cooling system. One circuit, utilizing chiller technology, maintains the laser source at its optimal temperature, while the other circuit independently cools the handheld welding gun and QBH connector. This ensures that operators can maintain a comfortable grip on the handle even during continuous, high-load welding cycles, effectively eliminating the thermal shutdown issues commonly found in earlier high-power systems
2. Next-Generation Ergonomic Dual-Oscillation Welding Gun Head
Controlling 6,000W of laser energy requires absolute precision. The newly designed welding gun is constructed from aerospace-grade aluminum alloy and advanced composite materials, resulting in a 15% weight reduction compared to the previous generation. It incorporates our proprietary electric “oscillation” technology, which enables the beam to oscillate at high frequency. This creates a wider, more forgiving molten pool that easily bridges misalignments and gaps of up to 2.5 millimeters—a critical feature when addressing the practical challenges of thick-plate fabrication.
3. Integrated Intelligent Wire Feeder
To further enhance its welding capabilities for thick materials, the JCT-WU-6000 comes standard with a fully synchronized dual-drive automatic wire feeder. The system’s central PLC precisely adjusts the wire feed speed based on the laser power and oscillation frequency, ensuring perfect volume filling for large joints and fillet welds without requiring the operator to rely on experience-based estimates
Comprehensive Safety and Global Compatibility
High power output requires absolute safety. The JCT-WU6000 series has received global certifications and bears the CE and FDA compliance marks.
The JCT-WU Series 6000W handheld fiber laser welding machine is now officially available for order through our network of authorized global distributors. To support this new product launch, we will roll out a comprehensive on-site training program to ensure that even operators with no prior laser operation experience can achieve perfect, high-strength welds within their first week of operation.
As the manufacturing industry continues to face challenges in recruiting skilled welders and the need for higher production capacity, we remain committed to providing engineering solutions that turn bottlenecks into competitive advantages.
