11601125 - Tweco 16FC-564 Flux Core Contact Tip, 5/64 Inch, 25-Pack

High-Performance Flux Core Contact Tips

The Tweco 16FC-564 Contact Tip is a specialized consumable engineered specifically for Flux Cored Arc Welding (FCAW) applications. Unlike standard tips designed for solid wire, the "FC" designation indicates a bore geometry optimized for the unique characteristics of flux-cored wires, which often exhibit slight diameter variations and seams. This 25-pack of contact tips is designed to accommodate 5/64-inch (2.0mm) wire, providing the precise electrical contact necessary for stable arc transfer in heavy-duty industrial environments.

Manufactured from high-grade copper alloy, these tips offer superior thermal conductivity and wear resistance. The 16 Series form factor is the industry standard for medium-to-heavy amperage welding, making these tips directly compatible with Tweco Professional No. 3, No. 4, No. 5, and No. 6 MIG guns, as well as many other MIG guns utilizing the 16 Series consumable platform. The 1.5-inch overall length ensures ample surface area for current transfer, reducing micro-arcing inside the bore that can lead to premature failure.

In structural steel fabrication, shipbuilding, and heavy equipment repair, the integrity of the electrical connection at the contact tip is critical. The Tweco 16FC-564 features a robust 3/8"-24 UNF thread that seats firmly into the gas diffuser, maintaining alignment and maximizing current flow. By selecting a tip specifically designed for flux-cored wire, operators can minimize burn-back and feedability issues, ensuring consistent weld quality and reduced downtime for consumable changes.
