The Lincoln Electric KP2744-364AT Copper Plus Contact Tip is a high-performance consumable designed specifically for the rigorous demands of aluminum MIG welding. Engineered for use with Magnum® PRO welding guns, this contact tip features a 3/64-inch (1.2 mm) bore tailored for aluminum wire feeding. Aluminum welding presents unique challenges, particularly regarding thermal expansion and conductivity; the KP2744-364AT addresses these with Lincoln's proprietary Copper Plus® technology. By utilizing a larger diameter mass, these tips contain more copper alloy, which significantly improves heat dissipation. This keeps the tip cooler during extended welding arcs, reducing the risk of the wire melting back to the tip (burnback) and ensuring consistent electrical conductivity.
One of the most frustrating aspects of high-amperage welding is the tendency for contact tips to fuse to the gas diffuser due to excessive heat and spatter accumulation. Lincoln Electric has solved this with their innovative Anti-Seize™ threads. The thread design on the KP2744-364AT features a flattened profile that reduces surface area contact where seizing typically occurs, ensuring that tip changes are quick and tool-free when necessary. This feature drastically reduces downtime in industrial environments where every minute of arc-on time counts.
Visibility is key when welding intricate aluminum joints. The tapered geometry of this contact tip allows the welder to access tighter spaces and maintain a clear line of sight to the weld puddle. Furthermore, the tapered shape works in conjunction with Magnum PRO nozzles to smooth gas flow, providing optimal shielding gas coverage—critical for preventing porosity in aluminum welds. Sold in a convenient pack of 10, these tips are an essential stock item for any fabrication shop utilizing Lincoln Magnum PRO systems for aluminum work.
