11601104 - Tweco 16S-45 Heavy Duty Contact Tip .045" (Pack of 25)

Reliable Performance with Tweco 16S-45 Contact Tips

The Tweco 16S-45 Contact Tip (Part Number 1160-1104) is a standard heavy-duty consumable designed to deliver consistent performance in demanding MIG welding environments. Engineered for use with 0.045-inch (1.2 mm) welding wire, this contact tip is a critical component for maintaining stable electrical transfer and arc quality. It is compatible with Tweco Spray Master and Tweco No. 6 MIG guns, as well as other welding guns that utilize the 16 Series consumable platform. Whether you are working in a fabrication shop or on a heavy industrial site, using genuine Tweco parts ensures that your equipment operates at its peak potential.

Manufactured from high-quality 122 DHP copper alloy, the 16S-45 tip offers excellent electrical properties. The choice of material is crucial for contact tips, as it directly influences conductivity and heat resistance. This tip features a thick-walled design that acts as an effective heat sink, conducting thermal energy away from the arc source. This thermal management capability helps to prevent overheating and premature wear, significantly extending the service life of the tip compared to standard light-duty alternatives. The tip is machined from copper alloy tubing, ensuring a smooth and consistent inside diameter surface that minimizes friction and promotes smooth wire feeding.

Precision is key in welding consumables, and the Tweco 16S-45 delivers with a nominal inner diameter of 0.054 inches, held to a strict tolerance of +/- 0.003 inches. This tight tolerance ensures optimal electrical contact with the wire without causing binding or drag. The tip features a standard M8 x 1.25 threaded connection, allowing for a secure and vibration-resistant fit into the gas diffuser. Each tip is clearly stamped with the part number and wire diameter, making identification quick and easy on the shop floor. Sold in packs of 25, these contact tips provide a cost-effective solution for high-volume welding operations requiring reliable and durable consumables.
