KP2745-764-B100 - Lincoln Magnum PRO Copper Plus Contact Tip 550A 7/64 (100 Pack)

Keep Your Arc Stable with Lincoln Magnum® PRO Tips

Welders know that the contact tip is the final transfer point for welding current, making it one of the most critical components in the MIG gun assembly. The Lincoln Electric KP2745-764 Copper Plus® Contact Tip (100 Pack) is designed to keep you welding longer with fewer interruptions. Built for the heavy-duty Magnum® PRO 550A guns, these tips are sized for large 7/64-inch (2.8 mm) wire, making them the go-to choice for structural steel, heavy equipment repair, and other thick-plate applications. This bulk pack of 100 ensures your shop is stocked up, saving you money and the hassle of frequent reordering.

Why Choose Copper Plus®?

Not all contact tips are created equal. Lincoln Electric's Copper Plus® tips are manufactured from a specialized alloy that outperforms standard copper in heat resistance and durability. When you are pushing 550 amps, heat buildup is your enemy. It causes tips to soften, the bore to wear out (keyholing), and the wire to wander. Copper Plus® technology helps the tip stay cooler and hold its shape longer. This means you get a consistent arc, better bead placement, and less frustration with burn-backs. For professional welders, this reliability means you can focus on the puddle rather than troubleshooting your gun.

Designed for the Magnum® PRO System

These tips feature the innovative Magnum® PRO connection system. The threads are designed to provide a larger contact patch with the diffuser, which improves conductivity and keeps the connection tight. Have you ever struggled to remove a fused tip? These tips feature anti-seize threads that resist welding themselves to the gun, making changeovers quick and painless. The 7/64-inch diameter is precision-drilled to provide the perfect balance between electrical contact and smooth wire feedability, ensuring that your wire glides through without snagging.

Value and Performance

Buying in bulk is the smart move for high-volume shops. The KP2745-764-B100 pack provides 100 premium contact tips, lowering the cost per tip and ensuring you always have a replacement on hand when you need it. Whether you are running flux-cored wire for deep penetration or solid wire for clean finishes, these tips deliver the performance Lincoln Electric is famous for. Upgrade your consumables to match the quality of your welding machine and experience the difference that Copper Plus® technology makes in your daily fabrication work.
