OVERVIEW

Reliable Feeding and Cooler Operation

Upgrade your welding performance with the Lincoln Electric KP2745-072R Copper Plus contact tip, the professional's choice for Magnum PRO MIG guns. When you are pushing high amperage day in and day out, your contact tip is the first line of defense against arc instability and burn-backs. The KP2745-072R is built with "Copper Plus" technology, which simply means there is more metal to handle the heat. The larger outer diameter pulls heat away from the wire exit point, keeping the tip cooler and significantly reducing the likelihood of the wire melting back or spatter adhering to the face.

One of the most frustrating aspects of MIG welding is a contact tip that won't come off when it's time to change it. Lincoln has solved this with their patented Anti-Seize™ threads. The threads are designed with a flattened profile that allows for thermal expansion and contraction without locking up inside the diffuser. This means you can spin the old tip off and thread a new one on in seconds, keeping your focus on the weld puddle rather than fighting with your torch. This feature is a massive time-saver in high-production environments.

Precision is the hallmark of a good weld, and it starts with consistent electrical contact. These tips feature tighter internal diameter tolerances than standard tips, ensuring the wire is guided directly to the center of the arc. This improves arc starting reliability and maintains a stable arc length, which is crucial when welding with .068" to .072" wires. Rated for up to 550 amps, these tips are designed for heavy fabrication, structural steel, and other demanding applications. Sold in a convenient 10-pack, the KP2745-072R ensures you have the high-quality consumables you need to keep your Magnum PRO gun running at peak efficiency.

FAQ

These contact tips are designed specifically for Lincoln Electric Magnum PRO MIG welding guns.

This tip is sized for wire diameters between .068 inches and .072 inches (1.7 mm to 1.8 mm).

Copper Plus tips have a larger diameter and mass, which improves heat dissipation and keeps the tip cooler, extending its service life.

The threads have a flattened profile that reduces the contact area with the diffuser, preventing the tip from fusing or seizing due to heat expansion.

These contact tips are rated for welding applications up to 550 Amps.

The KP2745-072R is sold in a package of 10 contact tips.

Yes, the tighter tolerances and resistance to annealing make it excellent for robotic applications requiring consistent Tool Center Point (TCP).

It is made from a Copper Chrome Zirconium alloy which offers better resistance to wear and annealing than standard copper.
