11601617 - Tweco EL16A116 Eliminator Contact Tip, 1/16" Aluminum, 25-Pack

Superior Aluminum Welding with Tweco Eliminator Tips

For professional welders tackling aluminum projects, the Tweco EL16A116 Eliminator Contact Tip is a game-changer. Welding aluminum presents a unique set of challenges compared to steel, primarily due to the softness of the wire and its high rate of thermal expansion. Standard contact tips often cause the wire to bind or "burn back" as it heats up and expands inside the tip. The EL16A116 is specifically engineered with an "A" designation, meaning it features a slightly larger internal clearance to accommodate this expansion, ensuring smooth, uninterrupted wire feeding for 1/16" (1.6 mm) aluminum wire.

The Eliminator series front-end consumables are designed to keep you welding longer with less downtime. The EL16A116 contact tip offers superior electrical transfer, which is vital for maintaining a stable arc in aluminum MIG welding. A stable arc results in cleaner welds, reduced spatter, and better bead appearance. The high-quality copper construction withstands the intense heat of the welding arc, resisting keyholing and wear that can degrade weld quality over time. With a pack of 25, you have plenty of replacements on hand, ensuring you can swap out a worn tip immediately and get back to the job.

One of the frustrations with aluminum MIG welding is "birdnesting" at the drive rolls or jamming in the liner. While the liner and drive rolls play a huge part, the contact tip is the final exit point. If the wire drags here, the whole system backs up. The smooth internal bore of the EL16A116 minimizes friction, allowing the soft aluminum wire to glide through effortlessly. This is particularly important when pushing wire over longer distances or when using push-pull guns compatible with Eliminator consumables.

Installing the EL16A116 is quick and easy, thanks to the Eliminator's user-friendly design. The tip seats securely into the gas diffuser, providing a solid electrical connection that won't loosen during operation. Whether you are fabricating aluminum boat hulls, repairing trailers, or working on aerospace components, using the correct contact tip is a small detail that makes a massive difference. Trust genuine Tweco Eliminator parts to deliver the precision and reliability your craftsmanship demands.
