11101311 - Tweco Velocity VTS-40 Contact Tip, 0.040 in (1.0 mm) - 10 Pack

Technical Overview of Tweco VTS-40 Velocity Contact Tips

The Tweco 11101311 (VTS-40) is a high-performance contact tip designed for the Velocity consumable platform, specifically engineered to accommodate 0.040-inch (1.0mm) welding wire. Unlike traditional MIG contact tips that rely on threaded connections, the Velocity system utilizes a threadless, drop-in design. This engineering choice addresses several critical failure points in standard MIG guns, primarily thermal bottlenecking and thread seizure. By eliminating the threads, the VTS-40 achieves a more substantial surface area contact with the gas diffuser, facilitating a more efficient transfer of welding current and a superior thermal path for heat dissipation.

Manufactured from high-grade solid copper, these tips are machined to precise tolerances to ensure consistent wire feeding and arc stability. The "VTS" designation stands for Velocity Tapered Standard, indicating a geometry that balances robust wall thickness with a tapered front end to improve operator visibility of the weld puddle. The integration of the tip into the Velocity system also means that the gas flow is optimized; the shielding gas ports are located on the diffuser but the tip's seating mechanism ensures a leak-proof seal that directs gas concentrically around the wire, reducing turbulence and porosity risks.

For industrial procurement and maintenance planning, the VTS-40 offers significant value by reducing downtime associated with consumable changeovers. The drop-in nature allows for rapid replacement without the need for pliers or wrenches, and the cooler operating temperature extends the lifespan of the tip compared to threaded counterparts. This package contains 10 contact tips, ensuring a ready supply for production environments utilizing 1.0mm wire in mild steel, stainless, or aluminum applications where the Velocity system is deployed.

Compatibility is key: these tips are designed for use with Tweco Fusion series MIG guns and any other Tweco platform (such as Spray Master) that has been converted to the Velocity consumable system. They are not compatible with standard threaded diffusers found on legacy Tweco #2 or #4 guns without the appropriate conversion parts.
