11601759 - Tweco VTM-564 Velocity Contact Tips 5/64 Inch (Pack of 10)

Tweco Velocity2 VTM-564 Contact Tip Overview

The Tweco Velocity2 VTM-564 Contact Tip (SKU: 11601759) represents a significant advancement in MIG welding consumable technology, specifically engineered for medium-duty applications requiring a 5/64" (approx. 2.0mm) wire size. Part of the renowned Velocity2 series, these contact tips are designed to address the most common pain points associated with traditional threaded consumables. By utilizing a threadless, drop-in design, the VTM-564 eliminates the risk of cross-threading or seizing, ensuring that maintenance and changeovers are rapid and tool-free. This design innovation not only saves time but also enhances the mechanical and electrical connection between the contact tip and the gas diffuser.

Technically, the VTM series optimizes the electrical surface contact area. Traditional threaded tips often suffer from fluctuating conductivity as threads wear or loosen. The Velocity2 system employs a large surface area engagement that remains stable even under thermal expansion, providing a consistent current transfer to the welding wire. This results in a smoother, more stable arc and reduced voltage drop across the front-end consumables. The VTM-564 is rated for welding outputs up to 250 amps, making it an ideal choice for general fabrication and manufacturing environments utilizing Tweco Spray Master MIG guns equipped with Velocity consumables.

Furthermore, the internal geometry of the VTM-564 is precision-machined to optimize wire feedability. The centered liner path ensures that the wire feeds concentrically through the tip, reducing friction and micro-arcing inside the bore. This is particularly critical for larger diameter wires like 5/64", where feed resistance can lead to erratic arc performance. The tips are also designed to be rotatable; if keyholing begins to occur, the operator can simply rotate the tip to present a fresh wear surface to the wire, effectively extending the lifespan of the consumable before replacement is necessary. This package contains 10 genuine Tweco contact tips, ensuring a reliable supply for continuous operations.
