Hongniu handheld fiber laser welding machine integrates industry-leading design with versatility and performance to meet the demands of modern fabrication and repair applications. With power options from 1.5 kW to 3 kW, it enables seamless welding of stainless steel, carbon steel, aluminum alloy and other materials, while maintaining ultra-clean weld seams and minimal heat-affected zones. The ultra-light welding gun (≤ 0.7 kg) offers comfortable, ergonomic handling and access to complex geometries. With advanced features such as a swing-weld head, ergonomic gun design, fast-swap lenses, dual-temperature chiller (in the FMW series) and multi-mode functions (weld/cut/clean in the HW series), this machine boosts productivity, reduces re-work, and supports continuous operation. Its compact footprint supports mobile usage or flexible workshop environments.
