10461138 - Tweco Smoke Master 400A Fume Extraction MIG Gun, 15ft, Lincoln Connection, 1/16 Wire

Advanced Fume Extraction for Industrial Welding

The Tweco Smoke Master S415L116-15FT-LIN (SKU: 10461138) is a premium air-cooled MIG gun designed specifically for source capture of welding fumes. Engineered to meet the rigorous demands of heavy industrial fabrication, this 400-amp gun integrates a high-efficiency vacuum chamber directly into the handle and nozzle assembly. By capturing fumes at the generation point—the arc—the Smoke Master significantly reduces the welder's exposure to hazardous particulates, including hexavalent chromium and manganese, helping facilities comply with OSHA and ISO air quality standards.

This specific configuration is tailored for compatibility with Lincoln Electric wire feeders, featuring a direct-plug Lincoln backend connection. It comes pre-configured with a liner and contact tip setup for 1/16-inch (1.6mm) welding wire, making it an immediate solution for structural steel, heavy equipment manufacturing, and shipbuilding applications where larger diameter wires are standard. The 15-foot cable assembly offers a generous working radius, allowing operators to navigate around large workpieces without repositioning the feeder.

Technically, the S415 series is built for durability. The coaxial cable design houses the power conductor, gas hose, and control leads within the vacuum hose, protected by a rugged outer sheath that resists cuts, burns, and abrasion. The gun is rated for a 60% duty cycle at 400 amps using CO2 gas, ensuring it can withstand long arc-on times associated with high-deposition welding. The extraction nozzle is designed to efficiently pull smoke away without disturbing the shielding gas envelope, preventing porosity and ensuring weld integrity. Maintenance is straightforward, with standard Tweco consumables that are widely available and easy to replace.

Investing in the Tweco Smoke Master S415 is an investment in both productivity and safety. It eliminates the need for cumbersome positioning of extraction arms, as the extraction point moves with the welder. This "source capture" method is widely recognized as the most effective engineering control for welding fumes.
