KP2745-045T - Lincoln Magnum PRO .045 Tapered Contact Tip (10-Pack)

Precision and Durability for Professional Welders

When you are under the hood, the last thing you want to worry about is your contact tip overheating or fusing to the gun in the middle of a critical pass. The Lincoln Electric KP2745-045T Magnum PRO Contact Tip is built to solve exactly these problems. Featuring Lincoln's Copper Plus® technology, this tip is designed with a larger diameter and more mass than conventional tips, allowing it to dissipate heat rapidly. This keeps the tip cooler, prevents the wire from sticking, and maintains a stable arc even when you are pushing 550 amps. If you are welding with .045" wire and need a tip that can keep up with high duty cycles, this is the upgrade your MIG gun needs.

The "T" in the SKU stands for Tapered, a feature that makes a massive difference when visibility is key. Unlike standard blunt tips that can obscure the weld puddle, the tapered design of the KP2745-045T gives you a clearer line of sight to the arc, allowing for better puddle control and more precise bead placement. This is particularly useful when welding in tight corners or deep V-grooves where access is limited. Despite the tapered end, the body of the tip retains the heavy-duty robustness required for industrial applications.

One of the most frustrating aspects of changing contact tips is dealing with seized threads. Lincoln has addressed this with their patent-pending anti-seize thread design. The coarse, flattened threads resist melting and deformation, meaning you can easily unscrew the old tip and install a fresh one without fighting the gun or damaging the diffuser. Whether you are running mild steel, stainless, or flux-cored wire, these tips provide the consistent electrical contact necessary for smooth, spatter-free welding. This pack contains 10 tips, ensuring you have plenty of backups for the long haul.
