Tweco, an ESAB brand, introduced Centrovac fume extraction MIG guns that remove welding fumes at the gun nozzle. When paired with the appropriate extraction unit, the guns reduce exposure to harmful fumes. The guns can assist with meeting particulate limits in the operator’s breathing zone and when working in confined areas or other situations with limited ventilation. Three models are available and each features a light, well-balanced ergonomic handle with the vacuum vent located at the front of the handle. This allows the operator to easily adjust fume extraction rates by simply turning a band.
