When it comes to MIG welding aluminum, precision and compatibility are paramount. The Tweco 16AS-364 Contact Tip is engineered specifically to address the unique challenges of feeding soft aluminum wire. Unlike standard steel tips, these "A" style tips feature a slightly oversized bore tolerance. This critical design element accommodates the rapid thermal expansion of aluminum wire as it heats up, preventing the wire from seizing or dragging inside the tip—a common cause of "bird-nesting" and erratic arcs.
This package contains 25 high-quality contact tips, making it an ideal choice for industrial fabrication shops and professional welders who demand consistency. Designed to fit the industry-standard Tweco No. 3 (300 Amp) and No. 4 (400 Amp) MIG guns, these tips integrate seamlessly into your existing setup. They thread securely into standard gas diffusers (such as the 34A or 34CT series) using a robust 3/8"-24 UNF thread.
Manufactured from premium copper alloy, Tweco 16 Series tips offer excellent electrical conductivity and heat transfer. This ensures that the welding current is transferred efficiently to the wire, resulting in a stable arc and superior weld bead profile. Whether you are fabricating aluminum trailers, repairing boat hulls, or working on architectural aluminum, using the correct consumable is the first step toward a quality weld. Stock up with this 25-pack to ensure your production line keeps moving without interruption.
