Tweco 415C Fume Extraction MIG Gun: Cleaner Air, Better Welding

The Tweco 415C Air-Cooled Fume Extraction MIG Gun (10261117) is a premium solution for industrial welders who prioritize safety without sacrificing performance. Designed by Tweco, a leader in welding gun technology, this "Smoke Master" series gun integrates high-volume fume extraction directly into the handle and nozzle assembly. By capturing welding smoke at the source—right at the arc—it significantly reduces the amount of hazardous particulate matter entering the welder's breathing zone and the surrounding shop environment.

Rated at 400 Amps (60% duty cycle with CO2), the 415C is built for heavy-duty fabrication tasks. It features a 10-foot cable that combines the power conductor, liner, and vacuum hose into a single, durable assembly. This specific model comes equipped with a standard Tweco rear connection, ensuring it plugs seamlessly into wire feeders that utilize the industry-standard Tweco adapter. The air-cooled design simplifies setup by removing the need for water cooling lines, making it an excellent choice for mobile fabrication stations or shops where simplicity is key.

At Josef Gas, we understand that modern welding standards require strict adherence to air quality regulations. The Tweco 415C helps shops meet OSHA requirements regarding hexavalent chromium, manganese, and other weld fume constituents. Despite its added functionality, the gun remains relatively ergonomic, featuring a handle design that balances the weight of the vacuum hose to minimize operator fatigue during long shifts.
