10261122 - Tweco 400A Fume Extraction MIG Gun, 15ft, Miller Style

Industrial Source Capture Solution

The Esab Tweco 415C Air-Cooled Fume Extraction MIG Gun (SKU: 10261122) represents a critical advancement in welding safety and industrial hygiene. Designed for heavy-duty fabrication environments, this 400-amp air-cooled gun integrates high-efficiency fume extraction directly into the handle and nozzle assembly. By capturing hazardous welding fumes right at the arc—before they can enter the welder's breathing zone or disperse into the facility—the 415C aids significantly in compliance with OSHA and other safety regulations regarding hexavalent chromium and manganese exposure.

Engineered with the legendary durability of the Tweco brand, this gun features a robust 15-foot cable assembly that houses the power cable, liner, and vacuum hose within a protective outer sheath. The connection is specifically terminated for Miller wire feeders and power sources, ensuring a seamless plug-and-play experience for shops already utilizing Miller equipment. The gun is rated for 400 amps at a 60% duty cycle when using CO2, making it suitable for structural steel, heavy equipment manufacturing, and general industrial fabrication.

Performance and Ergonomics

Despite the added functionality of the vacuum system, the Tweco 415C maintains a focus on operator comfort. The handle is designed to balance the weight of the vacuum hose, minimizing wrist strain during prolonged use. An adjustable slide valve on the handle allows the welder to regulate the suction airflow manually, preventing shielding gas disturbance while maintaining effective fume capture. The front-end consumables are standard Tweco parts, meaning maintenance teams can utilize existing inventory of tips, nozzles, and diffusers, reducing operational complexity and cost.
