11401209 - Tweco 14-564 Contact Tip 5/64" (2.0mm) - Pack of 25

Reliable Arc Performance with Tweco 14-564 Tips

Every welder knows that the contact tip is the final transfer point for welding current, and its condition directly affects the quality of the arc. When you are running heavy 5/64-inch wire, you need a contact tip that can handle the heat and deliver current smoothly without snagging or overheating. The Tweco 14-564 contact tip is the industry standard for a reason—it offers a perfect balance of durability and performance for your Tweco MIG guns. Whether you are welding thick structural beams or repairing heavy machinery, these tips help maintain a stable, crisp arc that puts the metal where you need it.

One of the biggest frustrations on the shop floor is burnback or an erratic arc caused by a worn-out tip. As the bore of a contact tip wears into an oval shape (keyholing), electrical contact becomes intermittent, leading to sputtering and poor weld bead appearance. By keeping a fresh pack of 25 Tweco 14-564 tips in your toolbox, you ensure that you can swap out a worn tip the moment performance drops, keeping your production line moving. These tips are designed to fit the trusty Tweco #2, #3, and #4 guns that are the workhorses of the welding world, so you likely already have the compatible diffusers and nozzles on hand.

Installation is quick and easy with the standard 1/4"-28 thread. Simply unscrew the old tip, check your gas diffuser for any spatter buildup, and thread in the new 14-564 tip. Remember not to overtighten—snug is enough to ensure good electrical flow. The 5/64" size is specific for larger wire diameters often used in flux-cored or high-deposition MIG welding, so having the correct tip size is non-negotiable for feeding performance. Don't let a cheap or worn tip ruin your weld; stick with the proven quality of Tweco 14 Series consumables.
