OVERVIEW

Precision Engineering for 5/64" Wire Applications

The Tweco 14-564 Contact Tip represents the standard of excellence for heavy-duty MIG welding consumables. Designed to accommodate 5/64" (2.0mm) wire, this tip is part of the widely used 14 Series, known for its versatility and robustness in industrial environments. This package contains 25 genuine OEM tips, providing a cost-effective solution for high-volume welding operations that require frequent consumable changes due to high heat and amperage.

Technically, the 14-564 is machined from a specialized copper alloy tubing that provides a consistent and smooth inside diameter surface. The internal diameter tolerance is held to a strict +/- .003", which is critical for maintaining optimal electrical contact with the wire while minimizing drag. This precision fit reduces micro-arcing inside the tip, a common cause of premature failure and unstable arcs. The tip features a standard 1/4"-28 UNF thread, ensuring a secure mechanical and electrical connection to the gas diffuser, which helps in effective heat dissipation.

These contact tips are compatible with standard Tweco gas diffusers (such as the 52, 52-23, 54A) and fit seamlessly into Tweco Classic No. 2, 3, 4, and 5 MIG guns, as well as many other Eliminator and Spray Master series guns that utilize the 14-series geometry. The 1.5-inch length is optimized to position the arc correctly within the nozzle, providing adequate gas coverage for the weld pool.

For professionals running flux-cored or solid wires of 5/64" diameter, the Tweco 14-564 offers the reliability needed for critical welds. The stamped part number ensures you are always using the correct size, preventing feeding issues associated with mismatched tip-to-wire ratios. By choosing OEM Tweco parts, you ensure that your equipment operates at its rated duty cycle and performance levels.
