Every welder knows that the contact tip is the last point of contact before the arc strikes, making it one of the most important parts of your MIG gun. If your tip is worn out or poorly made, you're going to fight the puddle, deal with erratic feeding, and waste time clearing burnbacks. The Tweco 11-45 Contact Tip is the industry standard for running .045" wire, designed to keep your arc stable and your day productive. These are genuine 11 Series tips, built to fit the classic Tweco guns you likely have in your shop, from the light-duty No. 1 up to the heavy-duty No. 4.
Why stick with genuine Tweco? It comes down to the copper. These tips are made from a high-quality copper alloy that handles heat better than cheap generics. When you are running long beads, heat buildup causes the tip to expand, which can pinch the wire and cause drag. Tweco's alloy is formulated to resist this expansion and maintain a consistent bore size, letting the wire slide through smoothly while still making solid electrical contact. The result is a crisp start every time and a stable arc that goes where you point it.
This pack of 25 is perfect for the busy shop. You don't want to be digging around for a spare tip when you're in the middle of a project. With 25 tips in the box, you can keep a handful in your toolbox, some in the supply cabinet, and never get caught short. Whether you are welding mild steel, stainless, or flux-core, if you are running .045 wire through a Tweco-style gun, these are the tips you need to get the job done right.
