OVERVIEW

Heavy-Duty Tweco Contact Tips for Industrial Fabrication

The Tweco WeldSkill WS15H-564 Contact Tip is a premium consumable designed for high-amperage MIG welding applications requiring 5/64-inch (2.0mm) welding wire. Part of the renowned WeldSkill series by ESAB, these contact tips are engineered to provide a balance of professional-grade performance and operational economy. The "15H" designation indicates that these tips belong to the heavy-duty 15 Series, characterized by a thicker wall and larger outer diameter compared to standard light-duty tips. This additional mass is critical for heat dissipation during prolonged welding cycles, reducing the risk of overheating and premature failure in industrial environments.

Manufactured from high-quality copper alloy, the WS15H-564 ensures optimal electrical conductivity, which is essential for maintaining a stable arc and consistent weld penetration. The bore is precision-drilled to tight tolerances, accommodating 5/64" wire with just enough clearance to prevent binding while maximizing electrical contact. This specific SKU (1150-1235) is packaged in a quantity of 25, making it an ideal stock item for maintenance, repair, and operations (MRO) departments and heavy fabrication shops that consume consumables at a steady rate.

These contact tips feature a standard 3/8"-24 UNF thread, making them compatible with a wide range of Tweco MIG guns, particularly the heavy-duty No. 5 and No. 6 models, as well as any MIG gun setup configured to accept 15 Series consumables. Whether running solid wire or flux-cored wire in structural steel, shipbuilding, or heavy equipment manufacturing, the WS15H-564 delivers the reliability required to keep production lines moving efficiently.

FAQ

This contact tip is designed for use with 5/64 inch (approx. 2.0mm) welding wire.

The '15' refers to the Tweco 15 Series of consumables, and the 'H' stands for Heavy Duty, indicating a thicker wall for better heat resistance compared to standard tips.

This package contains 25 individual contact tips.

It depends on your diffuser setup. Typically, No. 4 guns use 14 series tips. The 15H series is larger (3/8"-24 thread) and is standard on Tweco No. 5 and No. 6 guns. You would need a gas diffuser that accepts 15 series tips to use this on a smaller gun.

Yes, 5/64" is a common diameter for flux-cored wires, and the heavy-duty design of the 15H tip is well-suited for the high heat of FCAW applications.

The thread size is 3/8"-24 UNF.

While you can physically use it if the wire size matches, aluminum usually requires slightly oversized tips (e.g., a tip marked for 3/32" might be used for 5/64" aluminum) to accommodate thermal expansion. However, for 5/64" hard wire or flux core, this is the correct tip.
