OVERVIEW

Reliable Performance with Genuine Lincoln Electric Parts

When it comes to MIG welding, the smallest components often make the biggest difference in your final weld quality. The Lincoln Electric KP2105-2B1 Contact Tip is designed to provide consistent electrical contact and smooth wire feeding for your welding projects. This pack contains 10 high-quality contact tips, ensuring that you always have a fresh replacement on hand when you need it most. Whether you are a hobbyist working in a garage or a professional fabricator in a busy shop, using genuine Lincoln Electric consumables helps maintain the integrity of your equipment and the quality of your work.

These contact tips are specifically engineered for use with .045 inch (1.2 mm) welding wire, a common size for structural and heavier-gauge fabrication. Over time, contact tips wear out due to the intense heat and friction of the moving wire. A worn tip can lead to an erratic arc, poor bead appearance, and frustrating wire feed issues. By keeping this 10-pack in your toolbox, you can quickly swap out a worn tip and get back to welding with minimal downtime. The tips feature a specific 5/16 inch length and 18-thread design, manufactured to Lincoln's strict tolerances for a perfect fit with compatible welding guns.

Investing in OEM parts like the KP2105-2B1 ensures that your welding setup operates as intended. Generic tips often suffer from poor machining or inferior copper alloys, which can overheat quickly and fuse to the wire. Lincoln Electric's commitment to quality means these tips offer excellent conductivity and durability. They are suitable for a variety of applications, including mild steel, stainless steel, and flux-cored welding processes where .045 wire is utilized. Keep your arc stable and your welds clean with these essential consumables.

This package is an essential addition to your welding supplies. Regular maintenance of your MIG gun's front-end consumables is the key to preventing common welding problems. With ten tips in a single package, you get excellent value and the peace of mind that comes with using parts from a trusted industry leader. Upgrade your consumable inventory today and experience the difference that precision engineering makes in your daily welding tasks.

FAQ

This contact tip is designed specifically for use with .045 inch (1.2 mm) welding wire.

The package contains 10 individual contact tips.

The tip is specified as 5/16 inches (7.9 mm) long with an 18-thread design.

Yes, this is a genuine Lincoln Electric KP2105-2B1 part.

The 18-thread specification ensures the tip screws securely into the compatible gas diffuser or gun neck, providing necessary electrical contact and mechanical stability.

Replace the tip when the bore becomes oval-shaped, causing erratic arc or wire wandering, or if the wire fuses to the tip (burnback).

While it fits .045 wire, aluminum usually requires specific tips with slightly larger bore tolerances due to thermal expansion. Standard copper tips like this are best for steel.

Yes, as long as the flux-cored wire diameter is .045 inches, this tip is suitable.
