Centrovac Fume Extraction MIG Guns

Centrovac fume extraction MIG guns remove welding fumes at the gun nozzle to help meet OSHA and ACGIH standards. When paired with the appropriate extraction unit, the guns reduce exposure to hexavalent chromium, manganese, aluminum, and other harmful fumes. The guns assist with meeting particulate limits in the operator’s breathing zone and when working in confined areas.

To meet customer needs in a variety of applications using solid, cored or aluminum wires, Tweco offers three models of fume extraction MIG guns:

• The Tweco Centrovac 482°F (250°C) air-cooled unit is for light-duty fabrication applications; it has a rating of 250A at 60% duty cycle and can accommodate wire diameters up to .039 in.
• The Tweco Centrovac 779°F (415°C) air-cooled gun meets the needs of medium and heavy-duty fabrication. It has a rating of 60% duty cycle at 380A and can accommodate wire diameters up to 1/16 in.
• The Tweco Centrovac 788°F (420°CW) water-cooled MIG gun is for heavy-duty welding and long duty cycles. Its high cooling flow rate allows the front end of the gun to cool more rapidly. It has a rated duty cycle of 100% at 430A and can use wires up to 1/16 in. diameter.

Each gun features a light, ergonomic handle with the vacuum vent located at the front of the handle allowing the operator to easily adjust fume extraction rates by simply turning a band. The gun’s back-end design is available in multiple connections and adapts to most brands of wire feeders. Centrovac guns use standard Tweco PSF consumables.
