Welding nozzles, gasless parts introduced for welding at high amperages

April 15, 2008

Bernard has introduced a line of heavy-duty and gasless Centerfire™ components, designed to help reduce operator downtime and improve weld quality for companies that weld at high amperages or change frequently between GMAW and self-shielded FCAW.

The components feature thick walls, a heat-resistant insulating material, and a removable nozzle cone. They are suitable for applications using mixed gases, for spray transfer processes, for thick aluminum welding, and for other situations in which the heat transferred to the consumables is increased.

The removable nozzle cone allows operators to replace the cone without having to remove and replace the entire nozzle. The removable cone also helps simplify cleaning. The heavy-duty nozzles feature a built-in spatter guard designed to improve weld puddle protection. They are available in various configurations, with several nozzle orifices and tip recesses.

For companies that use the same power source for GMAW and self-shielded welding, the gasless parts allow operators to convert a Q-gun from one process to the other. Operators remove the nozzle and replace it with a tip holder and insulator, which are designed to help improve visibility and joint access for self-shielded applications.

Applications for the nozzles include shipbuilding, trailer fabrication, and other heavy-equipment manufacturing operations. Both the nozzles and gasless parts operate with the standard contact tips and diffusers. The company says both can be used with any major brand of GMAW gun through the use of its conversion parts.
