12401862 - Tweco Velocity VNM62SC MIG Nozzle, 5/8" Bore (2-Pack)

Technical Overview of Tweco Velocity VNM62SC Nozzles

The Tweco 1240-1862 (VNM62SC) is a high-performance MIG welding nozzle designed for the Velocity consumable platform. This nozzle features a 5/8-inch (15.9 mm) bore, making it suitable for a wide range of medium to heavy-duty industrial welding applications where adequate gas coverage is critical. The VNM62SC utilizes Tweco's proprietary Velocity technology, which replaces traditional threaded connections with a threadless, drop-in style. This design integrates the contact tip seating area directly into the nozzle structure, optimizing electrical conductivity and heat transfer.

Constructed from solid copper, the VNM62SC is engineered to dissipate heat more efficiently than standard two-piece or insulated nozzles. The absence of threads eliminates the common issue of nozzles seizing to the conductor tube or gas diffuser, significantly reducing downtime during consumable changeovers. This specific SKU is supplied as a package of two nozzles, ensuring operators have immediate replacements available. It is directly compatible with Tweco Fusion MIG guns and Spray Master guns that have been retrofitted with Velocity conductor tubes.
