12201207 - Tweco VNS-FC Velocity Flux Core Nozzle (Pack of 2)

Tweco VNS-FC Velocity Flux Core Nozzle (Pack of 2)

The Tweco VNS-FC Velocity Flux Core Nozzle is an essential consumable for welders utilizing self-shielded flux-cored arc welding (FCAW-S) processes. Specifically engineered for the Tweco Velocity consumable platform, this nozzle is designed to fit seamlessly with Tweco Fusion 140, Fusion 180, Fusion 220, and Fusion 250 MIG guns. By replacing the standard gas nozzle used in MIG welding, the VNS-FC provides targeted protection for the contact tip and gas diffuser threads without directing shielding gas, which is unnecessary for self-shielded wires.

One of the primary challenges in flux-cored welding is the generation of heavy spatter, which can adhere to exposed gun components and seize threads. The VNS-FC nozzle acts as a robust insulator and shield, covering the sensitive gas ports and threads of the conductor tube. This protection prevents molten metal and slag from building up in critical areas, ensuring that your contact tip remains easy to remove and your gun remains operational for longer periods. The nozzle is constructed from high-quality, heat-resistant materials capable of withstanding the intense temperatures associated with flux-cored welding.

As part of the Velocity system, this nozzle benefits from Tweco's innovative design approach. The Velocity line is known for its superior conductivity and cooler running temperatures, achieved through solid copper conductor paths and fewer threaded connections. While the VNS-FC is a protective shield rather than a conductive gas nozzle, it integrates perfectly with the Velocity contact tips to maintain the system's overall efficiency. This pack contains two nozzles, ensuring you have a spare on hand for continuous productivity in the shop or on the job site.

Key Benefits:

• Specialized Design: Tailored specifically for gasless flux-core applications where shielding gas is not required.
• Component Protection: Effectively shields the gas diffuser and retaining threads from damaging spatter and slag.
• System Compatibility: Direct fit for Tweco Fusion series guns (140/180/220/250) utilizing Velocity consumables.
• Durability: Built to endure the harsh environment of flux-cored welding, reducing replacement frequency.
