11601770 - Tweco Velocity VTH-764 Contact Tip 7/64" (Pack of 10)

High-Performance Velocity Contact Tips

The Tweco 1160-1770 VTH-764 Velocity Contact Tip represents a significant evolution in MIG welding consumable technology. Engineered for heavy-duty industrial applications utilizing 7/64-inch (2.8mm) wire, these tips utilize Tweco's proprietary Velocity™ platform. Unlike traditional threaded tips, the Velocity system employs a threadless, drop-in design that integrates the gas ports directly into the tip base. This innovation eliminates the risk of cross-threading and seizing, common issues in high-heat environments where thermal expansion can lock components together.

Constructed from high-grade copper, the VTH-764 ensures a solid electrical connection with the conductor tube. The design maximizes surface area contact, facilitating efficient heat dissipation and maintaining lower operating temperatures even at high amperages. This thermal management extends the lifespan of the consumable and ensures consistent arc characteristics. The "VTH" designation indicates a heavy-duty specification, suitable for demanding fabrication tasks where arc stability and wire feed consistency are paramount.

By removing threads, the electrical path is shortened and made more robust, reducing resistance and improving the transfer of welding current to the wire. This results in a smoother arc and reduced spatter. The tips are easily rotated to optimize wear life before replacement is necessary, providing excellent value and performance for automated or manual welding setups.
