The Tweco Smoke Master SM400 (SKU: 10461108) is a high-performance air-cooled MIG gun designed for source capture of welding fumes. Engineered for industrial environments, this gun integrates a vacuum chamber and hose directly into the handle and cable assembly, allowing for the immediate removal of particulate matter and gases generated during the welding process. This specific configuration is rated for 400 Amps at a 60% duty cycle using CO2 gas, making it suitable for heavy fabrication, structural steel, and high-deposition flux-cored applications.
The gun features a 15-foot cable assembly that houses the power cable, liner, gas hose, and vacuum hose within a durable outer sheath, often reinforced with leather for abrasion resistance. The rear connection is a standard Tweco style, ensuring compatibility with a wide range of wire feeders equipped with Tweco adapters. This unit comes pre-configured for 1/16-inch (1.6mm) welding wire, utilizing a specific liner and contact tip setup optimized for this diameter. The front-end consumables are compatible with standard Tweco 14 series parts, simplifying inventory management for MRO departments.
Operational efficiency is maintained through an adjustable slide valve located on the handle, which allows the operator to regulate the vacuum flow volume (CFM). This is critical for balancing fume capture efficiency against the potential for shielding gas turbulence. When paired with an appropriate high-vacuum, low-volume extraction unit, the Smoke Master SM400 meets stringent industrial hygiene standards for hexavalent chromium and manganese exposure control.
