The Tweco 1160-1111 (Model 16S-3/64) is a standard heavy-duty contact tip engineered for industrial MIG welding applications using 3/64-inch (1.2mm) wire. Part of the widely utilized 16S series, this consumable is designed to fit Tweco Professional Series No. 3, No. 4, and No. 5 MIG guns, as well as the Spray Master series (350A and 450A). The tip features a 3/8"-24 UNF thread, allowing it to screw securely into standard 54A gas diffusers, ensuring optimal electrical conductivity and thermal transfer.
Manufactured from high-quality copper alloy, the 16S-3/64 tip offers excellent resistance to wear and erosion caused by the friction of the moving wire and the intense heat of the welding arc. The bore is precision-drilled to tight tolerances to provide a stable electrical contact point without causing excessive drag on the wire. This balance reduces micro-arcing inside the tip, which prolongs the lifespan of the consumable and maintains a consistent arc characteristic during welding.
This product is supplied in a package of 25, making it an economical choice for high-volume fabrication environments. The heavy-duty design features a thicker wall compared to the 14-series tips, providing greater heat sink capacity and durability for higher amperage welding procedures. It is suitable for use with solid wires, aluminum wires (where 3/64" is common), and flux-cored wires of the corresponding diameter.
