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

Maximize Your Welding Uptime with Heavy-Duty Contact Tips

Keep your production line moving and your welds consistent with the Tweco Style 16S-45 Heavy Duty Contact Tip. Designed for the professional welder who demands reliability, this contact tip is built to handle the heat of high-amperage MIG welding. Whether you are working on heavy structural steel, automotive fabrication, or general industrial repairs, the quality of your contact tip directly influences the stability of your arc and the quality of your bead. This 25-pack ensures you have plenty of stock on hand, minimizing downtime caused by frequent trips to the supply room.

The 16S-45 is specifically engineered for .045-inch wire, a standard size for many industrial applications. Its heavy-duty construction means it has more copper material than standard tips, allowing it to withstand higher amperages—up to 600 amps—without overheating or melting prematurely. This durability translates to fewer tip changes per shift and more arc-on time. If you are using Tweco Spray Master guns or the popular Eliminator series front-end parts, these tips are a perfect fit, screwing in smoothly to your existing gas diffusers (like the EL52CT-16 or HD54-16).

Don't let poor conductivity ruin your weld. A worn contact tip can cause erratic feeding, sputtering, and burnback, leading to frustrating troubleshooting and wasted material. By switching to these high-quality generic replacements, you get the performance of the original equipment manufacturer (OEM) part at a fraction of the cost. The precision-machined bore ensures the wire glides through smoothly while maintaining the solid electrical contact needed for a crisp, hot arc.
