10462226 - Tweco S2462HV High Volume Nozzle for Smoke Master MIG Guns

Tweco S2462HV Smoke Master High Volume Nozzle

The Tweco S2462HV is a specialized high-volume replacement nozzle designed exclusively for the Tweco Smoke Master series of air-cooled fume extraction MIG guns. Engineered to support heavy-duty industrial welding, this nozzle is rated for applications up to 450 Amps. In the realm of fume extraction welding, the nozzle plays a dual role: it must direct the shielding gas to protect the weld pool while simultaneously allowing the vacuum shroud to capture hazardous fumes generated at the arc. The S2462HV is optimized to balance these needs, providing a wide bore that facilitates high-volume fume intake without turbulence that could disrupt shielding gas flow.

Constructed from high-grade copper alloy, this nozzle offers excellent thermal conductivity, helping to dissipate the intense heat generated during high-amperage welding. This durability ensures a longer service life in demanding fabrication environments. As a genuine Tweco component, it guarantees a precise fit with the Smoke Master conductor tube and gas diffuser, preventing gas leaks and ensuring consistent electrical performance. Regular inspection and replacement of the nozzle are essential for maintaining the effectiveness of the fume extraction system and the quality of the weld.

This nozzle is an essential consumable for shops prioritizing welder health and safety through source-capture ventilation. It is compatible with standard Tweco Smoke Master air-cooled configurations and is designed for easy removal and installation, minimizing downtime during maintenance.
