Specification Brand : HARFINGTON BulletPoint : Package list: 12pk tip ( 10-PK Contact Tips + 1-PK Gas Diffuser + 1-PK Nozzle ) BulletPoint1 : Size - Nozzle orifice: 12.5mm / 1/2"; nozzle length: 55mm / 2.17"; package content: 2 x gas welding nozzles. BulletPoint2 : Material - The gas welding nozzle is made of copper, which has good wear resistance, is not easy to deform, and has a long service life; it has good electrical and thermal conductivity, can more effectively transmit current and dissipate heat, and reduces energy loss. The surface is nickel-plated to improve corrosion resistance, can remain stable in a humid environment, and cannot rust easily. BulletPoint3 : Feature - The conical surface design is conducive to airflow focusing, making the airflow more concentrated and accurate, thereby improving welding accuracy. The threaded design ensures that the gas welding nozzle is tightly connected to the welding equipment to avoid loosening or displacement, and improves the firmness during welding. BulletPoint4 : Application - This gas welding nozzle is suitable for 250L PRO curve 200 MIG gun 200A/300A/400A welding gun models. It is used for gas-shielded welding, gas cutting, and other metal processing operations during welding. It is suitable for welding workshops, construction, automobile manufacturing, ship repair, and other places. BulletPoint5 : Note - Before purchasing, please make sure you select the gas welding nozzle size that matches your welding gun model.
