12401882 - Tweco Velocity VNH752PC Heavy Duty Nozzle 3/4 Inch Bore Recessed

Heavy Duty Tweco Velocity Nozzles for Industrial Performance

The Tweco Velocity VNH752PC MIG Nozzle is a premium consumable designed to meet the rigorous demands of heavy industrial fabrication. Sold in a convenient package of 2, these nozzles are engineered for welders who require consistent performance, superior gas coverage, and extended consumable life. As part of the revolutionary Tweco Velocity™ system, this nozzle integrates seamlessly with Velocity conductor tubes and contact tips to provide a stable and efficient welding arc.

The VNH752PC model is a Heavy Duty variant featuring a substantial 3/4-inch (19.1 mm) bore. This large opening is critical for applications utilizing high amperage and spray transfer modes, where a broad envelope of shielding gas is necessary to protect the molten weld pool from atmospheric contamination. The nozzle is constructed from high-quality solid copper, ensuring excellent thermal conductivity that helps dissipate heat rapidly, keeping the front-end consumables cooler even during long duty cycles.

A key feature of this nozzle is its 1/8-inch (3.2 mm) recessed tip relationship. By positioning the contact tip slightly back inside the nozzle, the design offers enhanced protection against radiant heat and spatter, significantly prolonging the life of the contact tip. This recess also helps in maintaining a proper stick-out distance, which is vital for controlling voltage and arc characteristics in manual welding operations. Whether you are welding structural steel, heavy machinery, or pressure vessels, the Tweco Velocity VNH752PC ensures your MIG gun performs at its peak.

Key Benefits for the Welder

• Superior Gas Coverage: The wide 3/4" bore minimizes porosity risks in high-heat applications.
• Extended Durability: Heavy-duty copper walls resist deformation and melting.
• System Compatibility: Designed specifically for Tweco Spray Master™ V-Series and other Velocity-ready platforms.
