Engineered for High-Quality Oxygen (O₂) Cutting

Unlike single-layer variants, double-layer laser nozzles are specialized for carbon steel, mild steel, and low-alloy steel cutting using Oxygen (O₂) as an auxiliary gas. The dual-wall construction and 2.5mm orifice optimize gas velocity, preventing turbulence and allowing the oxygen to spark a clean, controlled exothermic reaction that rapidly removes molten metal without leaving heavy dross or carbon burrs.

Chromed T2 Copper Structure for Extended Lifespan

Manufactured from premium-grade T2 copper, this nozzle offers superior electrical and thermal conductivity. The advanced chromium electroplating forms a smooth, non-stick shield on the outer shell. This prevents cutting sparks, flying slag, and molten metal spatter from adhering to the tip, ensuring stable distance tracking and a significantly longer component service life.

Flawless Compatibility and Sensor Alignment

With an exact 32mm base diameter, 15mm height, and standard M14 threading, the 120GJT0620 guarantees a secure, leak-free seat on the laser head. Its precise physical alignment ensures reliable capacitance height sensing data, eliminating calibration errors and avoiding costly collisions between the laser head and the metal sheet during fast production cycles.
