The Tweco 1160-1607 (EL16AT364) is a premium contact tip designed for use with Tweco Eliminator series MIG guns, specifically tailored for welding with 3/64-inch (1.2mm) aluminum wire. In the world of industrial welding, using the correct consumable for the base material is not just a recommendation—it is a necessity. Aluminum wire is softer and expands more aggressively when heated than steel wire. Using a standard steel contact tip for aluminum often results in friction, shaving, and eventual fusion of the wire to the tip. The EL16AT364 solves this by featuring a slightly oversized ID (Inside Diameter) relative to the wire gauge, allowing for smooth feeding even under high-amperage thermal loads.
The Eliminator series consumables are distinguished by their robust design intended to lower operating temperatures and extend part life. The EL16AT364 utilizes a coarse thread or drop-in design (depending on the specific diffuser setup of the Eliminator line) that ensures a positive electrical connection. This solid seating is crucial for aluminum MIG (GMAW) welding, where resistance heating at the contact tip can cause erratic arc starting and porosity in the weld. By maintaining a cool running temperature, the tip retains its hardness longer, resisting the keyholing effect that degrades arc directionality over time.
This product comes in a package of 25, making it an economical choice for industrial environments where consumable turnover is a regular part of operations. The tapered geometry of the tip is particularly beneficial for fillet welds and complex assemblies, reducing the nozzle diameter profile to allow the gas cup to get closer to the work piece. This proximity improves shielding gas coverage—critical for aluminum, which is highly susceptible to atmospheric contamination and oxidation. Trust genuine Tweco parts to maintain the performance standards of your welding equipment and ensure the integrity of your aluminum fabrication projects.
