M16 Welding Nozzle 5 Pack Laser Cutting Nozzle, 35mm Height Copper Replacement Parts, Fit forLaser Welding Machine Wire Feeding Handheld Laser Welder Torch

• It is precision-machined from high-purity red copper with excellent electrical and thermal conductivity. This material can easily withstand the high-temperature environment generated during the laser cutting process, effectively preventing the nozzle from deformation or cracking. Its outstanding heat dissipation performance enables rapid transfer of local heat, extending the service life to 1.5 times that of ordinary brass nozzles; meanwhile, the red copper material ensures stable capacitance signal transmission, providing accurate data support for cutting thickness control
• Ultra-high concentricity of ≤0.03mm is achieved through CNC machining technology, ensuring perfect alignment between the laser beam and the center of the nozzle. This feature can effectively prevent issues such as one-sided molten residue and excessive melting of sharp corners on the cutting section, increasing the smoothness of the cut edge by 40% when cutting thick plates of 3mm or more
• It adopts an industrial-standard M16 threaded interface, which is perfectly compatible with Raytools power heads, CQWY handheld welding machines, Qilin series cutting heads, and 1000-2000W fiber laser equipment. Whether it is a large cutting machine in a metal processing workshop or a handheld welding device in a small workshop, seamless installation can be achieved, meeting the application needs of various scenarios such as hotels, manufacturing factories, and building material stores
• The innovative double-layer cavity design enables flexible switching between oxidative cutting and fusion cutting modes — when oxygen is used as the auxiliary gas (for carbon steel cutting), the outer cavity forms a high-pressure gas field to accelerate metal combustion; when switching to nitrogen for cutting stainless steel/aluminum plates, the inner cavity ensures stable gas flow and prevents the formation of an oxide layer. The surface undergoes anti-oxidation treatment, which reduces the adhesion of molten substances and extends the cleaning cycle to twice that of ordinary nozzles
• The thread surface has undergone special anti-slip treatment, allowing installation and disassembly to be completed by hand, which saves 50% of the replacement time compared with traditional nozzles. The bottom of the nozzle is equipped with a dual-protection structure consisting of a built-in silicone sealing ring and a metal retaining ring. This structure not only prevents pressure loss caused by the leakage of auxiliary gas but also blocks the rebound of molten metal splatters into the interior of the laser head, reducing the risk of focusing lens contamination by 60%
