KP2744-045T-B100 - Lincoln Magnum PRO 350A Tapered Contact Tip .045 (100-Pack)

Stay Cool and Weld Longer with Magnum PRO

Every welder knows the frustration of a contact tip failing in the middle of a critical pass. Burnback, micro-arcing, and erratic wire feeding are often symptoms of a tip that has overheated and lost its conductivity. The Lincoln Electric KP2744-045T-B100 Magnum PRO contact tips are built to solve exactly these problems. Rated for 350 amps and designed for .045" wire, these tips use Lincoln's Copper Plus alloy, a material formulation that resists heat buildup far better than generic copper tips. This means the tip stays cooler, the wire feeds smoother, and the arc remains stable for longer durations, even during high-duty cycle welding.

The "Tapered" design of this tip is a game-changer for visibility. When you are welding in a tight corner, a root pass on a pipe, or a complex structural joint, a bulky standard tip can block your view of the weld pool. The KP2744-045T features a slimmed-down front profile that lets you see exactly where the wire is hitting the joint. This improved visibility helps you maintain proper stick-out and gun angle, leading to higher quality welds with less rework. Despite the tapered end, the body of the tip retains enough mass to effectively pull heat away from the bore, preventing the wire from fusing to the tip.

Another feature welders will appreciate is the thread design. Magnum PRO tips use coarse threads that are less likely to cross-thread or seize up. When it is finally time to change the tip, it spins off easily without requiring excessive force or damaging the gas diffuser. The larger contact area of the threads also ensures that the welding current flows efficiently from the gun to the wire, giving you a crisp, responsive arc start every time. This 100-pack ensures you have a fresh supply of premium tips ready to go, keeping your booth running smoothly and your welds looking professional.

Whether you are running mild steel, stainless, or flux-cored wires, the stability provided by the Magnum PRO system allows you to focus on your technique rather than fighting your equipment. Upgrade your front-end consumables to Copper Plus and experience the difference in arc control and tip longevity.
