0558004246 - ESAB FC-5C Replacement Potentiometer 10K Linear 2W

Restore Smooth Amperage Control to Your FC-5C Pedal

Is your TIG welding foot pedal acting up? If you are experiencing jumpy amperage, dead spots where the arc cuts out, or an inability to reach full power, the culprit is likely a worn-out potentiometer. The ESAB 0558004246 is the genuine replacement potentiometer for the classic FC-5C foot control, designed to get your remote back to working like new. Over time, the carbon tracks inside a potentiometer wear down from the constant up-and-down motion of the pedal, causing erratic resistance readings that confuse your welder.

This isn't just a generic electronics part; it is a "High Life" 2-watt linear potentiometer built to handle the abuse of a shop floor. The linear taper is essential for TIG welding—it means that when you press the pedal halfway down, you get exactly half your set amperage, giving you the predictable control you need for critical welds on aluminum or stainless steel. A 2-watt rating ensures it won't burn out under load, providing years of reliable service.

Don't let a cheap electronic component ruin your weld quality. Replacing the potentiometer is a cost-effective way to save a foot pedal that might otherwise cost hundreds of dollars to replace entirely. This part is the exact spec required for the FC-5C, ensuring that your calibration remains accurate and your arc remains stable. Get back to stacking dimes with confidence by installing a fresh potentiometer in your remote.
