Tweco® introduces Centrovac fume extraction MIG guns

Tweco® has introduced three models of Centrovac fume extraction MIG guns that remove welding fumes at the gun nozzle to help meet OSHA and ACGIH standards. When paired with the appropriate extraction unit, Centrovac reduces exposure to hexavalent chromium (generated when welding stainless steel), manganese, aluminum and other harmful fumes. The guns can assist with meeting particulate limits in the operator’s breathing zone and when working in confined areas, inside tanks or other situations with limited ventilation.

To meet customer needs in a variety of applications using solid, cored or aluminum wires, Tweco offers three models of fume extraction MIG guns: (i) The Tweco Centrovac 250C air-cooled unit is designed for light-duty fabrication applications; (ii) The Tweco Centrovac 415C air-cooled gun meets the needs of medium- and heavy-duty fabrication like trailer manufacturing, shipyards, aerospace, tank and vessel welding; (iii) The Tweco Centrovac 420CW water-cooled MIG 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 by three to five times compared to air-cooled guns.
