KP2078-1B1 - Lincoln Electric KP2078-1B1 Aluminum Contact Tips .035 for Magnum 100L (10-Pack)

Reliable Aluminum Welding with Lincoln Electric

Achieving high-quality welds on aluminum requires precision and the right equipment. The Lincoln Electric KP2078-1B1 Contact Tip is specifically engineered to address the unique challenges of MIG welding with aluminum wire. Unlike standard steel tips, these contact tips are designed with slightly larger bore tolerances to accommodate the rapid thermal expansion of aluminum as it heats up. This critical design feature prevents the wire from seizing inside the tip, a common frustration that leads to burnback and downtime.

Designed to fit the popular Magnum 100L MIG Gun, these tips are a perfect upgrade for welders working on automotive repairs, signage, or light fabrication projects involving aluminum. The .035 inch (0.9 mm) size is standard for many aluminum applications, offering a balance of deposition rate and control. By using genuine Lincoln Electric consumables, you ensure that your equipment operates at peak efficiency, maintaining the smooth wire feed necessary for the soft nature of aluminum filler metals.

This package contains 10 contact tips, providing excellent value and ensuring you have plenty of replacements on hand for long projects. Aluminum wire can be unforgiving; having a fresh, clean contact tip is often the key to resolving arc instability or erratic feeding. Whether you are a professional fabricator or a serious hobbyist, stocking your shop with the correct consumables is the first step toward consistent, professional-grade aluminum welds.

Trust in the durability and precision of Lincoln Electric parts available at Josef Gas. These standard-duty tips are built to withstand the rigors of daily use while delivering the electrical conductivity required for a stable arc.
