639684 - ESAB Size 4 Welding Nozzle for W-Series Torches

Get the Perfect Flame for Your W-Series Torch

If you are running a classic W-250, W-300, or W-400 torch handle, you know that the quality of your flame dictates the quality of your weld. This #4A Welding Tip is built to deliver that soft, neutral flame you need to lay down smooth beads and control your puddle effortlessly. Whether you are brazing heavy castings or welding up 1/8-inch steel brackets, this tip gives you the heat control necessary to do the job right without fighting a sputtering flame.

Made from solid copper, this tip handles the heat like a champ. The swaged design isn't just for looks—it smooths out the gas flow so you get a consistent cone that doesn't wander. This means less time messing with your regulator settings and more time under the hood. It's a direct fit for your heavy-duty ESAB and Purox-style handles, so you can swap it out in seconds and get back to work. No leaks, no seating issues, just a reliable tool that works as hard as you do.

Don't let a worn-out nozzle ruin your weld appearance or compromise joint integrity. A fresh #4 tip restores your torch's performance, making puddle manipulation easier and reducing the chance of popping or flashback. Keep a few of these in your toolbox so you are always ready for medium-duty fabrication and repair tasks.
