KP2745-035-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip .035 (100-Pack)

High-Performance Consumables for Industrial Fabrication

The Lincoln Electric KP2745-035-B100 Copper Plus® Contact Tip is a premium consumable designed to meet the rigorous demands of heavy industrial welding. Engineered specifically for the Magnum® PRO 550 series of MIG guns, this contact tip represents a significant advancement in consumable technology. The "Copper Plus" designation refers to the tip's enhanced physical dimensions; by utilizing a larger diameter, Lincoln Electric has increased the total copper content of the tip. This additional mass acts as a superior heat sink, effectively drawing thermal energy away from the wire interface and dispersing it more efficiently than standard contact tips. For industrial operations running high-duty cycles at amperages up to 550A, this thermal management is critical for maintaining arc stability and preventing premature failure.

In addition to thermal benefits, these contact tips feature Lincoln's proprietary Anti-Seize™ threading. In high-heat environments, standard threads can often deform or fuse to the gas diffuser, leading to costly downtime and potential damage to the gun assembly during removal. The flattened thread profile of the KP2745-035 series prevents this seizing effect, ensuring that maintenance personnel can change tips quickly and easily without the need for excessive force or specialized tools. This feature directly translates to improved operational efficiency and reduced maintenance overhead.

This product is supplied in a bulk pack of 100 units (B100), making it an ideal inventory choice for large-scale manufacturing facilities, shipyards, and structural steel fabricators. The .035 inch (0.9 mm) bore is precision-machined to ensure optimal electrical contact with the welding wire, promoting consistent arc starts and reducing micro-arcing within the tip. By combining superior materials, intelligent thermal design, and practical maintenance features, the Lincoln Electric KP2745-035-B100 stands out as a top-tier solution for professional welding applications.
