The Tweco 15H-564 (SKU: 1150-1209) is a premium standard contact tip designed for industrial MIG welding applications utilizing 5/64-inch (2.0 mm) wire. Part of the renowned Tweco 15 Series, these tips are engineered to withstand the rigors of high-amperage welding environments, making them the standard choice for operators using Tweco No. 5 and No. 6 MIG guns. The "H" designation and the 15-series form factor indicate a robust design with a larger outer diameter and a substantial 3/8"-24 UNF thread, providing superior thermal transfer and mechanical stability compared to lighter-duty consumables.
Manufactured from high-grade copper alloy, these contact tips offer excellent electrical conductivity, which is critical for maintaining a stable arc and ensuring consistent weld penetration. The bore is precision-drilled to tight tolerances, ensuring smooth wire feeding while maintaining sufficient electrical contact to prevent micro-arcing inside the tip. This attention to detail reduces the frequency of burn-backs and extends the service life of the consumable, ultimately lowering downtime in production environments.
This product is supplied in a pack of 25, catering to high-volume fabrication shops and industrial maintenance departments. The 15H-564 is specifically sized for 5/64" wire, a diameter commonly used in heavy structural steel fabrication, shipbuilding, and heavy equipment manufacturing where high deposition rates are required. By using genuine Tweco consumables, users ensure perfect compatibility with their existing gas diffusers (such as the 55 and 55H series) and conductor tubes, maintaining the integrity of the MIG gun's gas shielding and current transfer systems.
Technical specifications include a standard length optimized for the nozzle relationship in Tweco heavy-duty assemblies. The 3/8"-24 thread allows for high torque retention, preventing the tip from loosening during thermal cycling. Whether running solid wire or flux-cored wires, the 15H-564 provides the reliability professional welders demand.
