The Lincoln Electric KP2745-364AT-B100 is a bulk package of 100 Magnum® PRO Contact Tips, specifically engineered for high-amperage aluminum welding applications. These tips are designed to accommodate 3/64-inch (1.2 mm) aluminum wire, featuring a specialized bore tolerance that accounts for the higher thermal expansion rate of aluminum compared to steel. This precise engineering reduces friction and micro-arcing within the tip, ensuring smooth wire feeding and stable arc characteristics essential for code-quality aluminum welds.
Manufactured using Lincoln's proprietary Copper Plus® technology, these contact tips offer superior hardness and thermal conductivity. The alloy composition resists keyholing and wear, providing a service life up to four times longer than standard copper tips. This durability is critical in automated or high-volume manual welding environments where downtime for consumable changes directly impacts productivity. The "Tapered" geometry (indicated by 'AT' in the SKU) provides a narrower profile at the arc end, facilitating better gas coverage and access into tight corners or deep V-grooves.
Rated for up to 550 Amps, these tips feature a larger mass than standard light-duty tips, acting as an effective heat sink to prevent overheating. The base of the tip utilizes flattened threads to maximize surface contact with the diffuser, improving electrical conductivity and reducing heat generation at the connection point. This bulk B100 pack is ideal for heavy fabrication shops, shipyards, and manufacturing facilities standardizing on the Magnum PRO platform.
