KP2745-564R-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip 5/64in 550A (100-Pack)

Experience Superior Arc Stability with Magnum PRO Copper Plus Tips

For professional welders, the contact tip is the critical transfer point of welding current to the wire. A worn or overheating tip can lead to micro-arcing, erratic feeding, and unstable arcs. The Lincoln Electric KP2745-564R Copper Plus Contact Tip is the premium solution for welders using Magnum® PRO MIG guns. Designed to handle the heat of 550A output, these tips feature a larger diameter and specialized alloy construction that keeps the tip cooler during extended welds. This thermal efficiency translates directly to a smoother arc and less spatter, giving you better control over the puddle.

This 100-pack of contact tips is sized for 5/64 inch (2.0 mm) wire, commonly used in heavy industrial applications. One of the standout features of the Copper Plus line is the anti-seize thread design. We've all struggled with tips that weld themselves to the diffuser after a long day of burning wire; Lincoln's flattened thread profile prevents this, ensuring that when it is finally time to swap the tip, it comes out easily without damaging your gun's front-end parts.

The extended life of these tips means you spend more time welding and less time walking back to the tool crib. The precision-drilled bore ensures excellent electrical contact with the wire, which is essential for maintaining consistent penetration and bead appearance. Whether you are welding thick structural plate or running hardfacing wire, these tips provide the durability and performance professional fabricators demand.

Key Benefits for the Welder

• Cooler Operation: Stays cooler than standard tips, preventing wire burn-back and sticking.
• Consistent Feeding: High-tolerance manufacturing reduces friction and drag on the wire.
• Easy Replacement: Threads designed to resist seizing, even after high-amperage cycling.
• Value Pack: The 100-count box ensures you have plenty of spares for the long haul.
