F4S Air-cooled Handheld Fiber Laser Welding Machine

Product Overview

The LNX-F4S is a 1600W air-cooled handheld fiber laser welder designed for professional workshops, metal fabricators, and manufacturers handling deep-penetration and high-throughput welding applications.

It welds stainless steel, aluminum, and carbon steel with a rated welding depth of up to 4 mm. The air-cooled design requires no separate water chiller, while continuous, pulse, and fish scale welding modes support a wider range of fabrication applications.

The F4S features a BWX20 welding gun, 0.8–1.6 mm single-wire or 1.2–1.6 mm dual-wire feeding, and a welding speed of 10–30 mm/s, making it suitable for pressure vessels, heavy machinery, structural fabrication, automotive frames, pipelines, shipbuilding, and other heavy-duty metal fabrication.

Key Features

1600W Air-Cooled System — High output for deep-penetration welding applications.
Single & Dual-Wire Feeding — Supports flexible filler wire configurations from 0.8–1.6 mm.
Fish Scale Welding — Supports decorative and controlled weld patterns with welding widths up to 8 mm.

The LNX-F4S is a practical choice for businesses seeking a high-output laser welding solution with flexible wire feeding and advanced welding functions for heavy fabrication.

Application Areas

The LNX- F4S Handheld Laser Welder is purpose-built for ultra-heavy industrial welding applications requiring maximum power and penetration depth. Ideal applications include: heavy-gauge stainless steel tank and pressure vessel manufacturing, thick aluminum alloy structural framework welding, carbon steel heavy machinery and equipment fabrication, automotive chassis and frame assembly, industrial pipeline and conduit construction, shipbuilding hull plate welding, bridge and infrastructure metalwork, heavy-duty mining and construction equipment manufacturing, and any application requiring deep penetration welding up to 4mm on ferrous and non-ferrous metals at production-line speeds.

Note: The LNX- F4S represents the pinnacle of the F-series handheld laser welders, More comprehensive functions. With an industry-leading 4mm welding depth capability, dual-wire feeding support (1.2-1.6mm), and the fastest welding speeds (10-30mm/s), the LNX- F4S is engineered for ultra-high-volume heavy fabrication where maximum penetration and productivity are critical. The advanced water-cooled thermal management system and upgraded 20um fiber core diameter ensure superior beam quality and sustained performance during extended high-power operation on thick materials.
