21K70 - ESAB W-200 Series Replacement Throat Mixer No. 30

Restore Your W-200 Torch to Peak Performance

If your trusty W-200 welding torch is sputtering, popping, or struggling to hold a consistent flame, the issue might be deeper than just a dirty tip. The ESAB 21K70 Throat Mixer No. 30 is the heart of your flame control, responsible for perfectly blending oxygen and fuel gas. When this part wears out or gets clogged with soot, your welding performance suffers, and the risk of flashbacks increases. Swapping out your old mixer for this genuine ESAB replacement is a quick and effective way to get your rig running like new again.

Designed specifically for the W-200 handle, this mixer drops right in without any modification. It’s built from heavy-duty brass, so it can take the heat and abuse of daily shop life. Whether you are doing fine detail welding, brazing pipes, or applying heat for bending, a clean and functioning mixer is what gives you that smooth, quiet, and controllable flame you need. Don't fight with a fluctuating flame that ruins your puddle; a fresh mixer ensures your gas ratios stay constant, letting you focus on your bead rather than adjusting your knobs every few minutes.

Safety is paramount in oxy-fuel welding. A damaged mixer can lead to unstable combustion inside the torch. By installing the 21K70, you are not just fixing a performance annoyance; you are ensuring the safety of your equipment. This part is an essential spare to keep in your toolbox. If you rely on your W-200 for critical repairs or fabrication, having a backup mixer means you won't be shut down by a clogged port or worn seat. Get back to welding with confidence using original ESAB parts.
