16401390 - Tweco Velocity VCT-50 MIG Nozzle, 1/2 Inch Bore, Conical (Pack of 5)

High-Performance Tweco Velocity VCT-50 Nozzles

The Tweco Velocity VCT-50 MIG Nozzle represents a significant advancement in welding consumable technology. Designed for professional fabricators and industrial applications, this nozzle is part of the renowned Velocity series, which redefines the gas delivery system in MIG welding. This specific model, the VCT-50, features a 1/2-inch (12.7 mm) bore and a conical shape, making it the standard choice for a wide range of welding tasks, from short-circuit transfer on thin gauge sheet metal to spray transfer on heavier plates.

Constructed from high-grade solid copper, the VCT-50 is engineered to withstand high amperage and reflective heat. The key innovation of the Velocity line is its integrated system approach. Unlike traditional slip-on nozzles that rely on O-rings or friction springs, the Velocity nozzle utilizes a threaded connection. This design ensures a secure, concentric fit onto the conductor tube, optimizing electrical conductivity and heat transfer. By effectively drawing heat away from the front end, the nozzle runs significantly cooler, which reduces spatter adhesion and extends the lifespan of the consumable.

This pack contains five (5) nozzles, ensuring your welding station remains stocked for continuous production. The conical geometry provides excellent gas coverage while maintaining a narrow profile, allowing welders better visibility of the arc and puddle, as well as improved access into corners and tight joints. Whether you are using a Tweco Fusion gun or a Spray Master upgraded with Velocity consumables, the VCT-50 delivers consistent gas flow and arc stability.
