Hongniu portable fiber laser welding machine integrates advanced air-cooling technology with a lightweight handheld design to achieve efficient and precise metal joining. With power options ranging from 0.8 kW to 2 kW, it delivers smooth, clean weld seams on stainless steel, carbon steel, and aluminum alloys. The compact size and ultra-light welding gun (≤ 0.7 kg) make it perfect for workshop use or on-site operations. Offering welding speeds three to five times faster than traditional TIG or MIG welding, it significantly reduces labor time and post-processing costs. The air-cooled system eliminates the need for water circulation, minimizing maintenance and improving portability.
