OVERVIEW

Reliable Feeding for Aluminum MIG Welding

Welding aluminum can be frustrating, especially when your contact tip isn't up to the task. The Lincoln Electric KP2745-364A5356 Copper Plus Contact Tip is designed to solve the specific headaches associated with running 3/64-inch aluminum wire. If you are welding with 5356 alloy, you know it feeds differently than steel or softer 4043 aluminum. This tip is precision-drilled to handle the specific expansion rates of 5356 wire, ensuring smooth feeding without the snagging or dragging that leads to birdnesting at the drive rolls.

Built for high-amperage guns (rated up to 550A), these tips are beefy enough to handle the intense heat of spray transfer aluminum welding without melting or deforming prematurely. The Copper Plus™ alloy resists wear better than standard tips, meaning you spend less time walking back to the tool crib for replacements and more time laying down beads. The larger diameter of the tip body also helps pull heat away from the wire exit point, reducing the chance of the wire fusing to the tip during stops.

These tips fit Lincoln Magnum PRO MIG guns and come in a convenient 10-pack, making them an essential stock item for any shop fabricating aluminum trailers, boats, or structural components. When your arc starts to stutter, or your wire starts to stick, upgrading to a tip specifically designed for your base material and wire alloy can make all the difference in weld appearance and productivity.

FAQ

This contact tip is designed for 3/64 inch (1.2 mm) welding wire.

Yes, the '5356' in the part number indicates the bore is optimized for 5356 aluminum alloy, which has different stiffness and expansion characteristics than 4043.

These tips are rated for use up to 550 Amps.

These are compatible with Lincoln Electric Magnum® PRO series MIG guns (semi-automatic and robotic).

Copper Plus is a proprietary Lincoln Electric alloy that provides better heat dissipation and wear resistance than standard copper, extending tip life.

This product is sold as a package of 10 contact tips.

While physically possible if the diameter matches, it is not recommended. The bore tolerance is loose to accommodate aluminum expansion; using it on steel may result in poor electrical contact and wandering arcs.

Aluminum expands significantly more than steel when heated. A standard tip would cause the aluminum wire to seize inside the bore, leading to burnback.
