KP2067-1B2 - Lincoln Electric 0.035 Aluminum Contact Tips (10-Pack)

Reliable Performance for Aluminum MIG Welding

Welding aluminum requires precision and the right consumables to ensure a strong, clean bond. The Lincoln Electric KP2067-1B2 Contact Tip is specifically designed to address the unique challenges of feeding aluminum wire. Sold in a convenient 10-pack, these contact tips are sized for 0.035-inch (0.9 mm) wire, making them an essential addition to your welding toolkit if you work with soft alloys.

Aluminum wire behaves differently than steel; it is softer and expands more significantly as it heats up. Using a standard contact tip designed for steel can often lead to feeding problems, such as wire shaving or the wire seizing inside the tip due to thermal expansion. The KP2067-1B2 tips feature a bore geometry optimized for aluminum, allowing for this expansion while maintaining excellent electrical contact. This results in a stable arc, reduced burnback, and less frustration during your projects.

Whether you are a hobbyist repairing a boat or a professional fabricator working on aluminum structures, using genuine Lincoln Electric consumables ensures compatibility and performance. These tips are built to the high standards Lincoln is known for, offering durability and consistency. Keep your MIG gun running smoothly and your welds looking professional by swapping out worn tips with these specialized aluminum contact tips.

Why Choose Specific Tips for Aluminum?

One of the most common issues in aluminum MIG welding is "birdnesting" or erratic feeding. While a spool gun or push-pull gun solves the mechanical feeding issues, the contact tip is the final transfer point for the welding current. If the tip is too tight (like a standard steel tip would be), the expanding aluminum wire drags and chatters. These Lincoln tips eliminate that variable, providing a smooth path for the wire to exit the gun and enter the weld pool.
