0700200197 - ESAB MXH Push-Pull Gun Potentiometer 2.5k

Get Your Remote Control Back

If you are welding with an ESAB MXH Push-Pull gun, you likely rely on the convenience of adjusting your wire speed right from the handle. It is one of the biggest advantages of the system, especially when you are working 20 feet away from your feeder on a large aluminum boat hull or a trailer body. However, when that little dial stops working, it becomes a major headache. You find yourself shouting to a helper to adjust the machine, or wasting time walking back and forth to dial in your settings. The ESAB 0700200197 Potentiometer is the direct replacement part you need to fix a broken or glitchy control knob and get back to welding efficiently.

Signs Your Potentiometer is Failing

How do you know if you need this part? Usually, the signs are obvious. You might notice that your wire speed jumps erratically even when you barely touch the dial. Or, you might find "dead spots" where the wire stops feeding entirely at certain knob positions. Sometimes, the knob simply spins freely without changing anything, or it feels gritty and rough. These are all symptoms of a worn-out potentiometer. In a shop environment filled with grinding dust and dirt, these electrical components eventually wear down. Swapping it out is a standard maintenance task that brings your gun back to like-new performance.

Installation and Fit

Because this is a genuine ESAB part, you don't have to worry about modifying your gun handle to make it fit. It is sized exactly for the MXH series torches. Installation typically involves opening up the gun handle (usually just a few screws), disconnecting the old pot, and connecting the new one. It’s a quick repair that can be done on a workbench in a few minutes. Don't let a small electrical part slow down your production. Keep your push-pull system running the way it was designed to—smooth, responsive, and under your complete control.

Why Genuine Parts Matter

While it might be tempting to find a generic electronic part, welding torches have specific requirements for durability and resistance values. Using the wrong resistance (like a 5k or 10k pot) will mess up your speed settings, making the dial extremely sensitive or barely responsive. Stick with the correct 2.5 kOhm OEM part to ensure your wire speed matches what you expect when you turn the knob.
