The ESAB Tweco Smoke Master SNA-415 (SKU: 10261120) is a high-performance air-cooled MIG gun designed for source capture of welding fumes. Engineered for heavy-duty industrial applications, this 400-amp gun integrates a vacuum chamber and shroud directly into the nozzle assembly, allowing for the efficient removal of hazardous particulate matter and gases at the point of generation. This specific configuration features a 10-foot cable assembly and a Miller-style rear connection, ensuring seamless compatibility with standard Miller wire feeders.
The gun is rated for 400 amps at a 60% duty cycle when using CO2 shielding gas, making it suitable for high-deposition structural steel fabrication, heavy equipment manufacturing, and general industrial welding. The coaxial cable design combines the power conductor, gas hose, and vacuum hose into a single, durable assembly that resists abrasion and heat. The vacuum shroud is adjustable, allowing operators to balance shielding gas coverage with fume extraction efficiency. The unit utilizes standard Tweco consumables, simplifying inventory management and maintenance procedures.
Integration with a high-vacuum extraction unit (sold separately) is required to operate the fume removal capabilities. The gun's design minimizes the bulk typically associated with fume extraction torches, maintaining a profile that allows access to moderately restricted joints while ensuring compliance with air quality regulations.
