KP2745-364AT - Lincoln Magnum PRO 3/64 Aluminum Contact Tip, Tapered, 550A (10-Pack)

Premium Aluminum Welding Performance with Lincoln Electric

The Lincoln Electric KP2745-364AT is a high-performance contact tip engineered specifically for the demands of aluminum MIG welding. Part of the renowned Magnum® PRO line, these contact tips are designed to address the unique thermal and feeding challenges associated with aluminum wire. Aluminum welding often requires higher amperages and generates significant heat, which can lead to premature tip failure or wire burn-back. The KP2745-364AT utilizes Lincoln's proprietary Copper Plus™ technology, which increases the diameter of the tip to provide a larger copper mass. This additional mass acts as a superior heat sink, effectively dispersing arc heat and keeping the tip cooler during extended welding sessions. The result is a contact tip that lasts longer, maintains better electrical conductivity, and reduces the frequency of interruptions for maintenance.

One of the standout features of this contact tip is the Anti-Seize™ threading. In heavy industrial applications, heat cycling can cause standard contact tips to expand and fuse to the gas diffuser, making removal difficult and often damaging the gun components. The Anti-Seize™ threads on the KP2745-364AT are flattened and designed to prevent this fusion, ensuring that tip changes are quick, consistent, and tool-free when necessary. This feature significantly improves operational efficiency in high-volume fabrication environments.

This specific model is sized for 3/64-inch (1.2 mm) aluminum wire and features a tapered geometry. The tapered shape is essential for welders who need to access tight corners or complex joint configurations without sacrificing gas coverage. Rated for up to 550 amps, these tips are built to withstand the rigors of heavy-duty manufacturing. Sold in a convenient package of 10, the Lincoln KP2745-364AT ensures your welding station is stocked with reliable consumables that deliver consistent arc stability and superior weld quality.
