The Lincoln Electric Magnum® PRO Copper Plus® 350A Contact Tips feature a revolutionary Anti-Seize™ Thread Design, which flattens the thread profile to enhance the cross-sectional area where heat concentration typically leads to failure. This design minimizes melting, fusion, and seizing, thereby significantly extending the service life of the contact tips. With fewer changes needed, these tips reduce labor and part costs while boosting arc time. Available in both standard and tapered designs, each package includes 10 pieces, rated for up to 350A at 100% duty cycle. These contact tips offer durability and reliability, optimizing welding performance for professional applications.
