OVERVIEW

Keep Your Aluminum Running Smoothly

Welding aluminum is tough enough without having to fight your equipment. If you are running 1/16" aluminum wire through a Magnum® PRO gun, the Lincoln KP2745-116AT Copper Plus® contact tip is the upgrade you need to keep your arc stable and your downtime low. These tips are built heavier and thicker than standard tips, meaning they stay cooler even when you are pushing 550 amps. A cooler tip means the wire doesn't soften and stick inside the bore—a common cause of the dreaded "burn-back" that stops production and forces you to reset your liner and drive rolls.

The "Tapered" design isn't just about looks; it helps you see what you are doing. When you are trying to lay a precise bead in a tight corner, the slim profile of this tip gives you a clear view of the puddle and ensures your shielding gas gets exactly where it needs to be. Because these are designed specifically for aluminum, the bore sizing is optimized to let the wire expand slightly as it heats up without jamming, giving you that smooth, buttery feed that makes aluminum MIG welding satisfying.

No More Stuck Tips

We have all been there: you go to change a worn-out tip, and it's welded itself to the diffuser. You grab the pliers, crank on it, and end up stripping the threads or ruining the diffuser. Lincoln's Anti-Seize™ threads solve this problem. The unique thread design prevents the tip from locking up, so when it's time for a fresh tip, you can twist the old one out easily by hand or with a light touch of a tool. This pack of 10 ensures you have plenty of backups on hand, though with the extended life of Copper Plus®, you won't be reaching for a new one nearly as often.

FAQ

These contact tips are designed exclusively for the Lincoln Electric Magnum® PRO series of MIG welding guns.

This tip is sized for 1/16 inch (1.6 mm) welding wire.

The 'A' in the SKU and the engineering specifications denote that the bore tolerance is optimized for aluminum wire, which expands more than steel when heated. Using a standard steel tip for aluminum can cause feeding issues.

Copper Plus tips have a larger diameter and mass, which improves heat dissipation. This keeps the tip cooler, extends its lifespan, and maintains better electrical conductivity.

Tapered refers to the shape of the tip's nose. A tapered tip is narrower at the end, allowing for better visibility of the weld pool and easier access into tight corners compared to standard flat tips.

The threads have a specialized profile that reduces the contact surface area slightly to prevent the metal from fusing (seizing) to the diffuser under high heat, making removal much easier.

This product is sold as a package of 10 contact tips.

While it may physically fit 1/16" steel wire, the bore is slightly oversized to accommodate aluminum expansion. For steel, it is recommended to use the standard steel version for optimal arc stability.
