KP2744-040-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip, 350A, .040 in, 100-Pack

Stay Cool Under Pressure with Copper Plus

Experience the difference that superior engineering makes in your daily welding operations with the Lincoln Electric KP2744-040-B100 Copper Plus Contact Tips. Designed for professional welders using Magnum PRO MIG guns, these tips address the most common frustrations associated with MIG welding: overheating, burn-back, and seized parts. Whether you are laying down long beads on structural steel or performing repetitive tacking, these contact tips provide the consistency and reliability you need to maintain a stable arc and produce high-quality welds.

Engineered for Heat Management

Heat is the enemy of contact tip life. As a tip gets hotter, the copper softens, the bore wears out (keyholing), and electrical conductivity fluctuates. Lincoln's Copper Plus technology combats this by increasing the diameter of the tip, packing more copper into the consumable. This extra mass pulls heat away from the wire interface faster, keeping the tip cooler. The result is a stable arc that tracks true, less spatter, and a tip that lasts significantly longer than standard alternatives. You spend more time welding and less time walking back to the tool crib for replacements.

Hassle-Free Maintenance

We've all dealt with contact tips that weld themselves to the diffuser, requiring pliers, vice grips, and frustration to remove. The KP2744-040-B100 features Anti-Seize Threading with a flattened thread profile that resists thermal expansion locking. This means the tip spins off easily when it's time for a change, saving your diffuser threads and your patience. This 100-pack ensures you are stocked up for the long haul, making it an excellent choice for busy shops running .040" wire at up to 350 amps.

Key Features for the Welder

• Cooler Operation: Larger copper mass dissipates heat to prevent wire burn-back.
• Stable Arc: Precision machined bore ensures consistent electrical contact.
• Easy Changeouts: Anti-seize threads prevent the tip from fusing to the gun.
• Heavy Duty: Rated for 350 amps, ready for industrial workloads.
