KP2745-035 - Lincoln Electric Magnum PRO Copper Plus Contact Tip - .035 in, 550A (10-Pack)

Superior Arc Stability with Lincoln Magnum PRO Copper Plus

The Lincoln Electric KP2745-035 Magnum PRO Contact Tip represents a significant advancement in MIG welding consumable technology. Designed specifically for the heavy-duty demands of industrial fabrication, these contact tips feature Lincoln's proprietary Copper Plus technology. By engineering the tip with a larger diameter and greater mass, Lincoln Electric has increased the copper content significantly compared to standard tips. This additional mass acts as a superior heat sink, effectively drawing thermal energy away from the bore and the arc zone. The result is a contact tip that runs cooler, maintains its structural integrity longer, and resists the keyholing effects that often lead to erratic arcs and burn-backs.

In high-amperage applications, heat buildup is the primary enemy of consumable longevity. The KP2745-035 is rated for up to 550 amps, making it an ideal choice for structural steel, heavy equipment manufacturing, and other intensive welding environments using .035" (0.9 mm) wire. Beyond thermal management, these tips address a common frustration for welders: seized components. The Magnum PRO tips are machined with Anti-Seize threading. This specialized thread profile accommodates the thermal expansion and contraction cycles inherent in welding without locking the tip into the gas diffuser. This ensures that when it is finally time to replace the tip, the changeover is quick, tool-free, and does not result in damaged diffusers or swan necks.

Reliability in the welding arc starts at the contact point. These tips provide consistent electrical transfer to the welding wire, ensuring a stable arc and reduced spatter. Whether you are running solid MIG wire or flux-cored variants, the precision bore of the KP2745-035 ensures smooth feeding and optimal conductivity. Supplied in a convenient pack of 10, these consumables are an essential stock item for any shop utilizing Magnum PRO 450 or 550 series MIG guns. Invest in consumables that reduce downtime and improve weld quality with Lincoln Electric's Magnum PRO series.
