12401886 - Tweco Velocity VNH75C Heavy Duty MIG Nozzle, 3/4" Bore, 1/8" Recess (2-Pack)

Tweco Velocity VNH75C Heavy Duty MIG Nozzle (1240-1886)

The Tweco® Velocity™ VNH75C (Part Number 1240-1886) is a premium heavy-duty MIG gun nozzle designed for the Velocity™ consumable platform. Engineered for industrial environments where durability and performance are paramount, this nozzle features a substantial 3/4-inch (19.1 mm) bore opening. The large bore size is critical for high-amperage welding procedures, such as spray transfer or flux-cored arc welding, where a high volume of shielding gas is required to protect the molten weld pool from atmospheric contamination. The nozzle is constructed from high-grade copper, ensuring excellent thermal conductivity to dissipate heat rapidly, thereby extending the service life of the consumable during prolonged welding cycles.

A key specification of the VNH75C is its 1/8-inch contact tip recess. By positioning the contact tip slightly inside the nozzle, the design provides a physical shield that reduces the accumulation of spatter on the tip face and minimizes the risk of arcing against the workpiece. This recess also helps focus the shielding gas column, improving coverage in drafty conditions or when welding in deep joints. As part of the Velocity series, this nozzle utilizes Tweco's innovative threadless, drop-in technology. Unlike traditional nozzles that screw onto a gas diffuser—often seizing due to thermal expansion and spatter—the Velocity nozzle clamps securely over the conductor tube, ensuring a consistent electrical path and easy removal.

This product is supplied as a package of two (2) nozzles, making it a cost-effective solution for maintaining inventory in high-production shops. It is directly compatible with Tweco Fusion™ MIG guns and any Tweco Spray Master™ or other MIG guns that have been retrofitted with the Velocity consumable system. The VNH75C is the ideal choice for fabricators requiring a robust, high-flow nozzle that reduces downtime associated with consumable changeovers.
