S7 Water-cooled Handheld Fiber Laser Welding Machine

Product Overview

The LNX-S7 is a 3000W water-cooled stationary fiber laser welder designed for professional workshops, metal fabricators, and manufacturers handling heavy-duty and deep-welding applications.

It welds stainless steel, aluminum, and carbon steel with a rated welding depth of up to 7 mm. The water-cooled system is designed for sustained high-power welding, while the benchtop workstation configuration provides a stable setup for demanding stationary industrial applications.

The S7 features a 50 μm fiber core, QBH/RD dual fiber interface, and 10 m output fiber for flexible workpiece positioning. Operating in continuous-wave mode, it is suitable for heavy machinery, pressure vessels, structural fabrication, automotive frames, pipelines, shipbuilding, mining equipment, and other heavy-duty welding applications.

With AC380V 50/60Hz three-phase power and a 220±20 kg configuration, the S7 is designed for industrial facilities requiring high-power stationary welding capability.

Application Areas

The LNX- S7 Water-Cooled Laser Welder is purpose-built for ultra-heavy industrial welding applications requiring maximum power and deepest penetration. Ideal applications include: extra heavy-gauge stainless steel industrial tanks and pressure vessels, thick aluminum alloy structural frameworks and heavy-duty components, carbon steel heavy machinery and large equipment fabrication, automotive heavy chassis and frame assembly, shipbuilding thick hull plate and structural welding, bridge construction and heavy infrastructure metalwork, mining and construction equipment manufacturing, industrial pipeline and heavy conduit construction, and any stationary welding application requiring deep penetration up to 7mm on ferrous and non-ferrous metals in the most demanding industrial environments.

Note: The LNX- S7 represents the absolute pinnacle of the S-series desktop water-cooled laser welders, delivering 50% more power than the S6 and 100% more than the S5. With its industry-leading 7mm welding depth capability, massive 50um fiber core diameter, and 3000W output, the LNX- S7 achieves unmatched penetration in a benchtop format. The AC380V three-phase power requirement and 220±20kg weight reflect the substantial engineering required for this level of sustained performance. For facilities with three-phase power infrastructure, the LNX- S7 delivers ultimate welding capability in a stationary workstation configuration.
