OVERVIEW

Reliable Feeding for Aluminum MIG Welding

Stop struggling with burnbacks and erratic feeding when welding aluminum. The Lincoln Electric Magnum® PRO Copper Plus® Contact Tip (KP2745-364AT5356) is built to handle the heat. Specifically designed for 3/64" (1.2 mm) 5356 aluminum wire, this tip takes the frustration out of aluminum fabrication. Aluminum wire is softer and expands more rapidly than steel when heated, which can cause it to drag or seize in a standard tip. Lincoln Electric has engineered this tip with the perfect bore tolerance to let 5356 wire glide through smoothly while maintaining the solid electrical contact needed for a stable arc.

Built to Last Longer

Time spent changing contact tips is time you aren't welding. That’s why the Copper Plus® design is a game-changer. These tips are thicker and heavier than your average contact tip, allowing them to disperse heat much more efficiently. This keeps the tip cooler, even when you are pushing 550 amps on heavy plate. A cooler tip means less wear, less keyholing, and fewer interruptions to your workflow. Whether you are building boat hulls, repairing trailers, or working on automotive parts, these tips deliver the consistency you need to lay down perfect beads.

Better Visibility, Better Welds

The tapered shape of this contact tip is designed with the welder in mind. It gives you a clear line of sight to the puddle, which is essential when you are moving fast on aluminum. It also helps you get the nozzle into tight spots without snagging. Sold in a convenient pack of 10, these tips are an essential addition to any shop running Magnum® PRO guns. Upgrade your consumables and experience the difference that a dedicated aluminum contact tip can make in your weld quality and daily productivity.

FAQ

This tip is specifically optimized for 5356 aluminum alloy wire. The bore tolerances are adjusted to account for the specific thermal expansion properties of 5356 aluminum.

This Magnum PRO contact tip is rated for high-amperage applications up to 550A.

While it is physically possible if the diameter matches, it is not recommended. The bore is slightly larger to accommodate aluminum expansion, which may cause poor electrical contact (micro-arcing) with steel wire.

Copper Plus refers to Lincoln Electric's design featuring a larger diameter and mass, which improves heat dissipation and extends the life of the contact tip.

No, this tip is designed specifically for the Magnum® PRO series of MIG guns and expendables.

The tapered design reduces the profile of the tip end, allowing for better visibility of the weld puddle and easier access into tight joints.

These contact tips are sold in a pack of 10.

This tip is sized for 3/64 inch (1.2 mm) wire.
