The Lincoln Electric KP2745-116-B100 represents the pinnacle of contact tip engineering for the Magnum® PRO series of MIG guns. Designed for 1/16" (1.6 mm) wire applications requiring up to 550A, these tips are built to withstand the extreme thermal stresses of high-amperage welding. This 100-pack offering provides a cost-effective solution for large-scale operations that demand consistency and longevity from their consumables. The core of this product's performance lies in two proprietary technologies: Copper Plus® and Anti-Seize™ threading.
Standard contact tips often fail prematurely due to overheating, which softens the copper and leads to keyholing (wear of the bore) or burn-back. Lincoln Electric's Copper Plus® technology addresses this by utilizing a larger outer diameter compared to standard tips. This increase in physical volume provides a greater thermal mass, which acts as a more efficient heat sink. By dispersing heat more effectively, the tip remains cooler during operation. A cooler tip maintains its structural integrity longer, ensuring consistent electrical conductivity and precise wire targeting over a longer service life.
Seized contact tips are a major cause of downtime and can lead to the destruction of costly gas diffusers. The KP2745-116-B100 features a specialized thread profile known as Anti-Seize™. This design incorporates a flattened thread crest that reduces the surface area in contact with the diffuser threads while maintaining a secure mechanical connection. This unique geometry prevents the thermal expansion and micro-arcing that typically cause tips to fuse or "freeze" in place. The result is a contact tip that remains easy to remove even after hours of high-heat welding.
These tips are classified as "Standard" relationship tips, meaning they sit flush or slightly recessed depending on the nozzle configuration, suitable for a wide range of spray transfer and globular transfer modes. By integrating these advanced features, Lincoln Electric ensures that the Magnum PRO system delivers superior arc performance and reduced consumable waste.
