639693 - ESAB 639693 Replacement Mixer Throat #15A for Oxy-Fuel Torches

Restore Your Torch's Performance

There is nothing more frustrating than trying to lay down a clean weld or heat a stubborn bolt when your torch flame won't behave. If you are experiencing a sputtering flame, popping sounds, or finding it impossible to dial in that perfect neutral flame, the issue might be buried inside your torch handle. The mixer is where the magic happens, and the throat is one of its most important parts. The ESAB 639693 Mixer Throat #15A is the genuine replacement part you need to get your equipment running like new again. Over time, carbon buildup, heat stress, and general wear can degrade the internal geometry of your mixer, killing your performance.

This isn't just a piece of brass; it's the component that ensures your oxygen and fuel gas mix smoothly and flow evenly to the tip. When the throat gets worn out or damaged, you lose control over your heat input. A fresh Mixer Throat #15A restores that smooth, consistent gas flow, giving you back the stable cone and defined feather you need for precise work. Whether you are welding thin sheet metal or heating up heavy plate, having a reliable torch is non-negotiable for professional results and shop safety.

Don't risk your safety or the quality of your work with worn-out equipment. A damaged mixer can increase the risk of flashbacks, which can damage your torch handle or worse. Swapping out the mixer throat is a smart, cost-effective maintenance step that extends the life of your expensive torch outfit. This part is built by ESAB to fit perfectly into compatible setups, meaning no fighting with threads or worrying about leaks. Keep a spare in your toolbox so you aren't left stranded in the middle of a job. Get your flame back to being hot, steady, and reliable with this high-quality replacement part.
