Condition: new, Year of construction: 2026, CORMAK WL3000 laser welding machine is a professional 3-in-1 device with a power output of 3000 W, designed for laser welding, cleaning, and cutting. It has been developed for industrial plants and workshops requiring reliability, precision, and high operating efficiency. Thanks to fiber laser technology, the machine provides exceptional beam stability and enables processing of a wide range of metal materials while maintaining a minimal heat-affected zone. Main advantages of the machine Maximum power of 3000 W – increased penetration depth and higher welding speed. Water cooling system – ensures stable operating conditions during continuous operation. Ergonomic welding head – lightweight and flexible, with adjustable spot size from 0–5 mm and interchangeable nozzles. Automatic dual wire feeder – integrated with the control system. Welding speed up to 215 mm/s – up to 10 times faster than traditional methods. Ability to process thin materials – for example stainless steel with a thickness of 0.5 mm. Operating modes: continuous / modulated – full control over weld parameters. Welding with or without wire – versatile technological solution. Cleaning and cutting functions – expanded range of applications. Design and technology The machine is based on a fiber laser source with a wavelength of 1070 nm and a 10 m fiber optic cable. Thanks to its compact housing and integrated connections for shielding gases and cooling systems, the CORMAK WL3000 ensures safe and efficient operation. The high-power welding head enables welding at various angles, while the optical system guarantees excellent beam quality and stability. Precision and work efficiency The CORMAK WL3000 laser welder enables fast and repeatable welds without the need for additional finishing operations. Due to the small heat-affected zone, the material structure remains unchanged. Low levels of reflected radiation improve operator safety while maintaining excellent final weld quality.
