Bernard Large Centerfire Nozzle is made of copper and has a 3/4" ID. It can accommodate "T" series contact tip and is compatible with all standard air-cooled Bernard MIG guns. Nozzle comes with a built-in spatter shield, which smoothens and concentrates gas flow for lowered weld oxidation as well as contamination. It is ideally suited for use in heavy-duty and light commercial applications and fits most competitive brand guns in order to improve the performance. Nozzle allows fixed tip positioning at 1/4" recess and is ideal for welding applications.
