Lincoln Electric KP2744-052 Copper Plus Contact Tip .052" 350A (10-Pack)

Keep Your Arc Smooth and Your Gun Cool

Every welder knows the frustration of a contact tip that overheats, keyholes, or fuses to the diffuser right in the middle of a job. The Lincoln Electric KP2744-052 Copper Plus® Contact Tip is built to solve exactly these problems. Designed for the Magnum® PRO series of MIG guns, this tip isn't just a piece of copper—it's a performance upgrade for your torch. The "Copper Plus" design puts more metal in the tip, creating a larger heat sink that pulls thermal energy away from the wire exit point. This means the tip stays cooler, lasts longer, and maintains a stable arc for extended periods, even when you are pushing 350 amps.

Changing tips should be a ten-second job, not a ten-minute wrestling match with a pair of pliers. That is why Lincoln equipped the KP2744-052 with Anti-Seize™ threads. The unique thread design reduces the contact area inside the diffuser, preventing the tip from seizing up due to thermal expansion or micro-arcing. When it is time to swap out a worn tip, it spins out smoothly, letting you get back to laying beads faster. This feature alone saves countless headaches and protects your gas diffuser from damage caused by stuck tips.

This specific tip is sized for .052 inch (1.3 mm) wire, a common choice for heavy fabrication where deposition rates matter. The bore is machined to tight tolerances to ensure excellent electrical contact with the wire without causing drag. Good electrical transfer is critical for a smooth, spatter-free arc, and the KP2744-052 delivers it consistently. Whether you are welding structural steel or heavy equipment, having a reliable contact tip means fewer interruptions and better weld quality.

Sold in a pack of 10, these tips are a must-have for your consumables kit. Don't let cheap, inferior tips slow you down or ruin your diffusers. Stick with genuine Lincoln Electric parts for your Magnum PRO gun. The combination of Copper Plus cooling and Anti-Seize threads makes the KP2744-052 one of the most reliable contact tips on the market, giving you the confidence to weld all day long.
