KP2745-035A-B100 - Lincoln Magnum PRO Copper Plus Contact Tip .035 Aluminum (100-Pack)

Smooth Feeding for Aluminum MIG Projects

Struggling with bird-nesting or burn-back when MIG welding aluminum? The tip you use makes all the difference. The Lincoln Electric Magnum PRO KP2745-035A contact tip is built specifically to solve the headaches associated with running .035" aluminum wire. Unlike standard tips designed for steel, these "A" style tips feature a precisely oversized bore. This allows the aluminum wire to expand as it gets hot without seizing inside the tip, ensuring a consistent feed and a stable arc from start to finish.

These tips are part of the Copper Plus series, meaning they are tougher and run cooler than generic copper tips. The larger diameter and specialized alloy draw heat away from the contact point faster, which prevents the tip from softening and deforming under high amperage. This is crucial for aluminum welding, where consistent electrical contact is key to preventing weld defects like porosity or lack of fusion. Whether you are welding boat hulls, trailers, or custom aluminum parts, these tips help you lay down high-quality beads with less frustration.

This 100-pack bulk box is perfect for busy shops that need to keep their Magnum PRO guns running without constant reordering. Compatible with Magnum PRO 350 and 550 guns, they snap right into your existing setup. Upgrade your consumables and experience the difference that a purpose-built aluminum contact tip can make in your daily welding operations.
