KP2745-035R - Lincoln Magnum PRO Copper Plus Contact Tip .035 550A (10-Pack)

Maximize Arc Time with Magnum PRO Copper Plus Tips

For professional welders, downtime is the enemy. Every time you have to stop to change a burned-back contact tip or wrestle with a seized thread in your diffuser, you are losing valuable arc time. The Lincoln Electric KP2745-035R Copper Plus™ contact tip is built to solve exactly these problems. Designed for use with Lincoln's Magnum® PRO MIG guns, these tips are engineered to handle the heat of heavy-duty welding, rated up to 550 amps. If you are running .035" wire and pushing your machine to the limit, these are the tips that will keep up with you. The secret lies in the "Copper Plus" design—these tips are physically larger and heavier than standard tips. That extra metal isn't just for show; it acts as a massive heat sink, pulling heat away from the wire and keeping the tip cooler, longer.

No More Seized Tips

One of the most frustrating experiences in MIG welding is trying to unscrew a contact tip that has fused itself to the diffuser. You end up damaging the diffuser, or worse, the gun neck, trying to get it loose. Lincoln Electric has addressed this head-on with their Anti-Seize™ thread technology. The threads on the KP2745-035R are designed with a unique profile that prevents the tip from melting and locking up inside the diffuser. This means when it is finally time to change the tip, it spins out easily, allowing you to get back to welding in seconds, not minutes. This feature alone saves significant frustration and protects your other gun components from damage during maintenance.

Precision and Consistency

Beyond durability, these tips offer superior welding performance. The internal bore is machined to tight tolerances for .035" (0.9 mm) wire, ensuring that the wire feeds smoothly and contacts the tip consistently. This results in a stable arc and precise wire placement, which is essential whether you are welding manually or overseeing a robotic operation. The Copper Chrome Zirconium material resists wearing out the hole into an oval shape (keyholing), which causes erratic arcs. With the KP2745-035R, you get a crisp, consistent arc start after start. Sold in a convenient pack of 10, these extended-life tips are an investment in smoother operations and higher quality welds.
