20312238 - Tweco 2031-2238 Potentiometer Assembly with Knob

Restore Precision to Your Welder with the Tweco 2031-2238 Potentiometer

When your welding machine's controls become erratic or unresponsive, it can severely impact the quality of your work. The Tweco 2031-2238 Replacement Potentiometer with Knob is the genuine OEM solution designed to bring your equipment back to optimal performance. Manufactured to the exact specifications of Thermal Arc and Tweco power sources, this component ensures that your voltage, amperage, or wire feed speed settings are accurate and stable.

Over time, the internal tracks of a potentiometer can wear down due to constant adjustment and exposure to shop dust. This often manifests as "dead spots" where the machine loses power, or jumpy settings that make fine-tuning the arc impossible. Replacing the faulty unit with this high-quality assembly eliminates these frustrations. The included knob ensures a fresh, secure grip and a professional appearance, replacing any worn or lost original dials.

Using authentic replacement parts like the 2031-2238 is critical for maintaining the longevity of your welding equipment.

This Tweco part guarantees a direct fit and correct electrical function, allowing you to install it with confidence and get back to welding quickly.
