K2 Air-cooled Handheld Fiber Laser Welding Machine
Product Overview
The LNX-K2 is a compact 550W air-cooled handheld fiber laser welder designed for metal fabricators, professional workshops, and manufacturers working with medium-thickness metal components.
It welds stainless steel, aluminum, and carbon steel with a rated welding depth of up to 2 mm. The air-cooled design requires no separate water chiller, while continuous and pulse modes support flexible welding applications.
The K2 features a DWS20 welding gun, 0.8–1.0 mm single-wire feeding, and a 29 kg compact configuration, making it suitable for industrial equipment, automotive components, metal furniture, structural fabrication, machinery repair, pipelines, and general metal manufacturing.
Key Features
550W Air-Cooled System — Higher output for medium-thickness metal welding applications.
Compact 29 kg Configuration — Suitable for workshops with limited floor space.
Continuous & Pulse Welding — Flexible modes for different fabrication requirements.
The LNX-K2 is a practical choice for businesses seeking a compact, higher-output laser welding solution for medium-thickness fabrication and repair.
Technical Specifications
Application Areas
The LNX- K2 Handheld Laser Welder is designed for medium-duty industrial welding applications including: stainless steel tank and vessel fabrication, aluminum alloy structural framework welding, carbon steel machinery component assembly, automotive exhaust system and chassis repair, metal furniture and architectural fixture manufacturing, industrial pipeline and conduit construction, general metal fabrication workshops, and any application requiring welding depth up to 2mm on ferrous and non-ferrous metals.
Note: The LNX- K2 delivers 57% more power than the K1 (550W vs 350W) with a 33% increase in welding depth (2mm vs 1.5mm). Despite the higher power output, the LNX- K2 maintains a compact footprint identical to the K3 and K4 models, making it an excellent choice for workshops requiring versatile mid-range welding capability without sacrificing floor space.
