K1 Air-cooled Handheld Fiber Laser Welding Machine

Product Overview

The LNX-K1 is a compact 350W air-cooled handheld fiber laser welder designed for small workshops, repair services, and manufacturers working with thin metal components.

It welds stainless steel, aluminum, and carbon steel with a rated welding depth of up to 1.5 mm. The air-cooled design requires no separate water chiller, while continuous and pulse modes support flexible welding applications.

The K1 features a DWS20 welding gun, 0.8–1.0 mm single-wire feeding, and a compact 25 kg design, making it suitable for kitchen equipment, sheet metal enclosures, electronics components, signage, metal furniture, automotive repair, and general precision fabrication.

Key Features

350W Air-Cooled System — Compact configuration for thin-metal welding applications.
Compact 25 kg Design — Suitable for small workshops and space-conscious working environments.
Continuous & Pulse Welding — Flexible modes for different precision welding applications.

The LNX-K1 is a practical choice for businesses seeking a compact and accessible laser welding solution for thin-metal fabrication and repair.

Application Areas

The LNX- K1 Handheld Laser Welder is ideal for light-duty precision welding applications including: stainless steel kitchenware and food equipment manufacturing, thin aluminum alloy decorative parts and jewelry welding, carbon steel sheet metal enclosure assembly, electronics and electrical component welding, signage and advertising metal fabrication, small-scale metal furniture production, automotive trim and accessory repair, and any application requiring precision welding on thin materials up to 1.5mm depth.

Note: The LNX- K1 is the entry-level model in the K-series, offering professional-grade laser welding at an accessible price point. While sharing the same 350W power output as the LNX- F1, the LNX- K1 features a slightly different form factor optimized for compact workshop environments. For applications requiring 2mm welding depth or higher power, please consider the LNX- K2 model.
