639994 - ESAB Replacement Mixer Throat #150 for Oxy-Fuel Torches

Keep Your Flame True

There is nothing more frustrating than trying to lay down a clean weld or make a precise cut when your torch is acting up. If you are experiencing a fluttering flame, difficulty setting a neutral flame, or hearing that popping sound that makes every welder flinch, the issue might be deep inside your torch handle. The ESAB 639994 Mixer Throat #150 is the genuine replacement part you need to get your rig back in fighting shape. It’s the piece inside the mixer that does the heavy lifting, blending your oxygen and fuel just right before it hits the tip.

Old mixer throats get clogged with soot or pitted from heat and age. When that happens, your gas flow gets turbulent in the wrong way, and your flame control goes out the window. Swapping out the throat is a smart, cost-effective repair that can save you from buying a whole new attachment. This is a solid brass piece, built to take the heat and keep on ticking. It fits right into compatible ESAB and Victor-style mixers, restoring that smooth, hissing flame you want to hear.

Don't gamble with aftermarket knock-offs when it comes to gas equipment. A poorly machined part can lead to leaks or flashbacks, putting you and your shop at risk. Stick with the real deal. This ESAB mixer throat is made to factory specs, so you know it fits and you know it works. Keep one in your repair kit or toolbox so you aren't left stranded in the middle of a job. Maintenance is part of the trade, and keeping your torch internals clean and fresh is key to quality work.
