264050 - Miller Replacement Potentiometer for RFCS-14 & 14HD Foot Controls

Restore Precision to Your TIG Welding

There are few things more frustrating in TIG welding than a foot pedal that doesn't listen to you. You press down for more power, and nothing happens—until suddenly the amperage spikes, blowing a hole in your material. Or perhaps you are trying to taper off at the end of a weld, and the arc flickers or cuts out prematurely. These are classic signs of a worn-out potentiometer in your foot control. The Miller 264050 Potentiometer with Leads is the genuine replacement part you need to get your RFCS-14 or RFCS-14HD foot pedal back to behaving like new.

Your foot pedal is the gas pedal for your welder; it needs to be smooth, responsive, and predictable. Inside the pedal, the potentiometer is the part that actually does the work of telling the machine how much power you want. Because it is a moving part, it eventually wears out from thousands of cycles of use. When it does, your control over the puddle suffers. Instead of buying a brand-new foot pedal, which can be a significant investment, you can often fix the issue simply by swapping out this internal component. This part is built by Miller for Miller, meaning it fits perfectly inside the housing and connects exactly as it should.

This kit comes ready to install with leads already attached, saving you the headache of trying to solder tiny wires in a tight space. It is designed to handle the shop environment and provide the smooth, linear response you expect from professional equipment. Whether you are working on critical aerospace parts or just fixing things in the garage, having reliable amperage control is non-negotiable.

Don't let a glitchy pedal ruin your welds or your patience. If your RFCS-14 or 14HD is acting up, check the potentiometer. Installing the Miller 264050 is a cost-effective maintenance step that restores the fine control necessary for high-quality TIG work, ensuring that when you ask for 5 more amps, you get exactly 5 more amps.
