KP2744-045 - Lincoln KP2744-045 Magnum PRO .045 Contact Tips (10-Pack)

Lincoln Electric KP2744-045 Magnum PRO Contact Tip Overview

The Lincoln Electric KP2744-045 is a premium contact tip designed specifically for the Magnum® PRO series of MIG welding guns. Engineered with Lincoln's proprietary Copper Plus® technology, this consumable offers superior performance and longevity compared to standard copper tips. The .045-inch (1.2 mm) diameter is precision-machined to ensure optimal electrical conductivity and smooth wire feeding, which are critical factors in maintaining a stable arc and achieving high-quality welds in industrial environments.

One of the standout features of the KP2744-045 is its material composition. The Copper Plus® alloy utilizes a larger diameter mass which allows for a higher copper content. This increased thermal mass effectively disperses heat generated during the welding process, keeping the tip cooler for longer periods. By managing thermal buildup, the tip resists softening and deformation, significantly extending its service life and reducing the frequency of changeovers. This translates to less downtime and higher productivity for welding operators.

In addition to its thermal properties, this contact tip features Anti-Seize™ threading. In high-amperage applications, contact tips can often fuse to the diffuser due to extreme heat and spatter accumulation. The specialized thread design of the Magnum PRO series prevents the tip from melting or seizing in the gas diffuser, ensuring that replacements are quick and tool-free when necessary. Rated for 350A applications, this tip is robust enough for heavy-duty fabrication while maintaining the precision required for detailed work.

This product is supplied in a convenient 10-pack, ensuring that welding stations remain stocked with essential consumables. It is compatible with Lincoln Magnum PRO 250L and other Magnum PRO 350A rated gun assemblies. Whether used in automotive manufacturing, heavy equipment repair, or general structural fabrication, the KP2744-045 delivers consistent current transfer and reliable wire guidance.
