KP14-52 - Lincoln Magnum .052 Contact Tip 10-Pack

Precision Performance for Industrial MIG Welding

The Lincoln Electric KP14-52 Contact Tip is a critical consumable designed to maintain the efficiency and quality of your MIG welding operations. Engineered specifically for use with Lincoln's renowned Magnum® 300 and Magnum® 400 MIG guns, this contact tip is sized for .052-inch (1.3 mm) welding wire. In high-amperage industrial environments, the contact tip serves as the final point of electrical transfer to the electrode wire. The KP14-52 is manufactured with tight tolerances to ensure that this transfer is consistent, minimizing voltage drops and ensuring a stable arc characteristic essential for structural and heavy fabrication work.

Constructed from a high-grade copper alloy, these tips are built to withstand the intense thermal cycling associated with welding in the 300 to 400-amp range. The material selection prioritizes thermal conductivity, which helps dissipate heat away from the wire-tip interface, reducing the likelihood of the wire fusing to the tip (burnback) and extending the service life of the consumable. The standard geometry of the tip ensures it fits perfectly within the gas nozzle, maintaining the proper stick-out and gas coverage required for defect-free welds.

This product is supplied in a convenient pack of 10, catering to the needs of busy workshops where downtime must be minimized. Regular replacement of contact tips is a standard maintenance procedure to prevent micro-arcing inside the bore, which can lead to erratic wire feeding. By choosing genuine Lincoln Electric parts like the KP14-52, operators ensure compatibility and reliability, preserving the performance standards of their Magnum MIG equipment. Whether used in automotive manufacturing, heavy equipment repair, or general steel fabrication, these contact tips provide the durability and precision professionals demand.

Proper storage and handling of these tips are recommended to prevent oxidation before use. The KP14-52 represents Lincoln Electric's commitment to quality, offering a consumable that supports smooth wire delivery and superior arc control for .052" wire applications.
