0558003776 - ESAB 15k Ohm Linear Potentiometer 2W 1-Inch Shaft

Restore Precision Control to Your ESAB Welder

Is your welder's voltage or wire speed jumping around unpredictably? Or perhaps the dial has become scratchy, loose, or completely unresponsive? A failing potentiometer is often the culprit behind these frustrating issues. The ESAB 0558003776 is the genuine replacement potentiometer you need to get your machine back to running smoothly. When you turn the knob on your welder, you expect the machine to react instantly and accurately; this high-quality component ensures that tactile connection between you and the arc is restored.

This 15,000 Ohm (15k) linear potentiometer is built to handle the rigors of the shop environment. With a 2-watt power rating, it is robust enough to last, providing years of reliable service. The linear taper means that when you turn the knob halfway, you get exactly half the output range—no guessing games or sudden jumps in power. It features a standard 1-inch shaft that fits your existing knobs perfectly, making installation straightforward for anyone comfortable with basic machine repair.

Don't let a small, inexpensive part compromise the quality of your welds. A drifting setting can lead to burn-through, lack of fusion, or messy spatter. By swapping out your old, worn-out pot with this factory-original ESAB part, you ensure your machine operates exactly as the engineers intended. Whether you are fixing a wire feeder or a power source, this potentiometer is the key to dialing in that perfect weld every time.
