Tweco Centrovac fume-extraction GMAW guns capture harmful fumes at the source

Tweco, an ESAB brand, has introduced three models of Centrovac fume-extraction GMAW guns that remove welding fumes at the gun nozzle. When paired with the appropriate extraction unit, the guns reduce exposure to hexavalent chromium (generated when welding stainless steel), manganese, aluminum, and other harmful fumes.

The 250C air-cooled unit is designed for light-duty fabrication applications. The 415C air-cooled gun meets the needs of medium- and heavy-duty fabrication, such as trailer manufacturing, shipyards, aerospace, tank, and vessel welding. The 420CW water-cooled gun is designed for heavy-duty welding and long duty cycles. Its high cooling flow rate allows the front end of the gun to cool more rapidly, extending consumables life.
