KP2745-116A - Lincoln Magnum PRO 550A Aluminum Contact Tip 1/16 (10-Pack)

Reliable Consumables for Heavy-Duty Aluminum Fabrication

Maximize your welding uptime and weld quality with the Lincoln Electric KP2745-116A Contact Tip, designed exclusively for use with Magnum® PRO 550A MIG guns. Welding aluminum presents distinct challenges, particularly regarding wire feedability and heat management. This contact tip addresses those challenges head-on with a purpose-built design for 1/16-inch (1.6 mm) aluminum wire. The internal bore is precision-machined to allow for the natural expansion of aluminum as it heats up, preventing the wire from binding inside the tip. This ensures a steady, uninterrupted feed, which is essential for producing porosity-free, high-quality aluminum welds.

Durability is a hallmark of the Magnum® PRO line, and these contact tips are no exception. Manufactured from Lincoln's exclusive Copper Plus® alloy, they are built to withstand the intense heat of 550-amp welding procedures without softening or deforming. This resilience means you spend less time changing out worn tips and more time welding, directly improving your shop's efficiency. The 10-pack packaging ensures you have a ready supply of consumables on hand for large projects, reducing the risk of unexpected downtime due to stockouts.

The KP2745-116A also features the innovative Magnum® PRO connection system. The contact tip threads securely into the gas diffuser with a design that promotes excellent electrical conductivity. A stable electrical connection is vital for maintaining a consistent arc length and reducing spatter, especially when welding aluminum which requires precise parameter control. Whether you are working in marine fabrication, trailer manufacturing, or general industrial repair, these contact tips provide the reliability and performance professional welders demand.
