Optimize your aluminum MIG welding setup with genuine Tweco 14A-364 contact tips. Designed expressly for 3/64-inch (1.2mm) aluminum welding wire, these consumables are a critical component for achieving consistent, high-quality welds. Aluminum wire behaves differently than steel; it is softer and expands significantly more when subjected to the heat of the welding arc. Using a standard steel tip for aluminum often results in the wire expanding and jamming inside the tip, leading to frustrating burn-backs and production stoppages.
The "A" designation in the 14A-364 part number signifies a specific internal geometry tailored for aluminum. The bore is precision-drilled to a slightly larger diameter than a standard .045" or 3/64" steel tip, providing the necessary clearance for the wire to expand without binding. This ensures smooth, uninterrupted wire delivery to the weld pool, which is crucial for processes like spray transfer often used with aluminum.
These tips feature the robust construction Tweco is known for, machined from conductive copper alloy to ensure efficient current transfer. They fit the ubiquitous Tweco 14 Series platform, making them compatible with the vast majority of medium-to-heavy-duty Tweco MIG guns found in industrial environments. Whether you are repairing aluminum trailers, fabricating boat hulls, or performing general maintenance, using the correct contact tip is the first step toward a defect-free weld.
