KP2744-116 - Lincoln Magnum PRO 350A Contact Tip 1/16 Inch (10-Pack)

Superior Thermal Management for High-Amperage Welding

The Lincoln Electric KP2744-116 Magnum® PRO Contact Tip represents a significant advancement in MIG welding consumable technology, specifically engineered for high-demand industrial environments. Designed to handle 350 Amperes and accommodate 1/16-inch (1.6 mm) wire, this contact tip integrates Lincoln's proprietary Copper Plus® technology. Unlike standard contact tips, Copper Plus® tips are manufactured with a larger outer diameter. This increase in mass allows for a greater volume of copper, which significantly improves thermal conductivity. By effectively acting as a heat sink, the tip disperses arc heat more rapidly, maintaining a lower operating temperature even during prolonged welding cycles. This thermal efficiency is critical in preventing tip deformation, keyholing, and maintaining consistent electrical transfer to the wire, which ultimately results in a more stable arc and higher quality welds.

Engineered for Reliability and Uptime

In addition to its thermal properties, the KP2744-116 features Lincoln's innovative Anti-Seize™ threading. In high-heat applications, standard threads can often fuse to the gas diffuser due to thermal expansion and micro-arcing, leading to seized components that require tools or force to remove—often damaging the gun in the process. The Anti-Seize™ design mitigates this risk by employing a specialized thread profile that accommodates thermal cycling. This ensures that the contact tip remains easy to remove and replace by hand or with minimal torque, even after being subjected to extreme heat. This feature directly translates to reduced downtime on the shop floor, as operators can perform consumable change-outs quickly and return to welding without frustration or equipment damage.

Precision and Compatibility

This contact tip is a core component of the Magnum® PRO ecosystem, designed to work seamlessly with Magnum® PRO MIG guns. The internal bore is precision-machined to strict tolerances for 1/16-inch wire, ensuring optimal electrical contact and arc stability. Poor contact can lead to micro-arcing inside the tip, burn-back, and erratic arc performance; the KP2744-116 is built to minimize these issues through superior manufacturing standards. Whether used in heavy fabrication, structural steel, or manufacturing, these tips provide the durability and consistency required for professional-grade welds. The package contains 10 contact tips, ensuring a ready supply for continuous operation and minimizing inventory management frequency for busy workshops.
