10261117 - Tweco Smoke Master 415C Fume Gun 400A 10ft

Technical Overview: Tweco 415C Smoke Master MIG Gun

The Tweco 415C (SKU: 10261117) is a specialized air-cooled MIG gun engineered for Source Capture Fume Extraction. In the welding industry, controlling exposure to metal fumes is critical, and the most efficient method is capturing contaminants immediately as they are generated. The 415C "Smoke Master" achieves this through a coaxial vacuum hose design and a specialized nozzle shroud that channels smoke away from the weld pool without compromising the shielding gas envelope.

Technically, this gun is rated for 400 Amps when using CO2 shielding gas and typically derated slightly for mixed gases (Argon/CO2 blends). The 10-foot cable length is optimal for bench work or production cells where the wire feeder is in close proximity to the workpiece, minimizing cable clutter and maximizing vacuum efficiency. The backend connection is a standard Tweco style (often referred to as a #4 or #5 connection depending on the specific adapter kit, but natively Tweco), making it a drop-in replacement for standard Tweco Spray Master or Classic guns on compatible feeders.

The gun utilizes a high-velocity, low-volume (HVLV) extraction principle. It requires connection to a separate high-vacuum extraction unit (portable or central system). The handle geometry is designed to accommodate the larger diameter required for airflow while maintaining a grip profile that allows for precise torch manipulation. The front-end consumables are based on the robust Tweco platform, ensuring that welders can rely on the longevity of the contact tips and diffusers even under the thermal stress of 400A welding.

Operational Specifications
