11601537 - Tweco 16S-45 Contact Tip for .045 Wire

Smooth Feeding and Consistent Arcs with Tweco 16PS Tips

Every welder knows that the contact tip is the unsung hero of the MIG gun. It’s the final point of contact where the power meets the wire, and if it’s not performing, your entire weld suffers. The Tweco 16PS Series Contact Tip (Part #11601537) is designed to keep you welding smoothly when running .045" wire. If you've ever struggled with a stuttering arc, burnback, or wire that seems to drag, a worn-out or low-quality tip is often the culprit. Upgrading to genuine Tweco 16PS tips ensures that your machine's power is transferred efficiently to the wire, giving you that crisp, frying-bacon sound you look for.

This tip features a 0.054" bore, which is the perfect size for .045" wire. It’s tight enough to ensure good electrical connection but has just enough clearance to allow the wire to feed without jamming, even if the wire has a slight cast or helix. Made from durable copper, these tips resist overheating and spatter adhesion better than budget alternatives. When you are in the middle of a project, the last thing you want is to stop every ten minutes to unclog a tip or deal with a fuse-back. With Tweco's reliable construction, you can spend more time under the hood and less time troubleshooting your gun.

Replacing your contact tip regularly is one of the cheapest and easiest ways to improve your weld quality. As tips wear, the hole becomes oval-shaped, causing the arc to wander and making it hard to aim your puddle accurately. By keeping a fresh stock of Tweco 16PS-45 tips in your toolbox, you ensure that your equipment is always ready for the job. Whether you are working on mild steel repairs, structural fabrication, or automotive frames, these tips deliver the consistency you need for professional-looking results.
