11501205 - Tweco 15H52 Heavy Duty Contact Tip 0.052" (25 Pack)

Heavy Duty Performance for Industrial Welding

The Tweco 15H52 Contact Tip is a premium consumable designed to meet the rigorous demands of heavy industrial fabrication. Engineered specifically for 0.052-inch (1.3 mm) welding wire, this contact tip is part of Tweco's renowned 15 Series, which features a heavy-duty construction. The "H" designation indicates a thicker wall design compared to standard duty tips, allowing for significantly improved heat dissipation. This thermal management is critical when welding at higher amperages, as it prevents the tip from overheating, softening, and deforming, thereby extending the lifespan of the consumable and reducing downtime for tip changes.

Manufactured from a high-quality copper alloy, the 15H52 ensures optimal electrical conductivity, which is essential for maintaining a stable and consistent welding arc. The bore is precision-drilled to tight tolerances, ensuring smooth wire feeding and minimizing the risk of micro-arcing inside the tip, which can lead to burn-backs and erratic weld quality. These tips are designed to fit Tweco No. 4 and No. 5 MIG guns, as well as other MIG guns that utilize standard Tweco-style consumables. Whether you are working on structural steel, heavy equipment repair, or general manufacturing, these contact tips provide the reliability professional welders expect.

This product comes in a convenient package of 25, ensuring you have an ample supply on hand for continuous production. By choosing genuine Tweco consumables, you ensure compatibility and performance consistency across your welding operations. The 1/4"-28 UNF thread allows for quick and secure installation into standard gas diffusers.
