23608212 - ESAB 50k Ohm Linear Potentiometer 2W Replacement Part

Technical Overview of the ESAB 23608212 Potentiometer

The ESAB 23608212 is a specialized linear potentiometer designed for integration into the control circuitry of ESAB welding power sources and wire feeders. As a variable resistor, this component plays a critical role in the user interface of industrial equipment, translating mechanical rotation into electrical signals that govern key welding parameters. The device features a resistance value of 50.0 kOhms (50,000 Ohms), a standard specification for voltage division circuits in analog control logic.

One of the defining characteristics of this component is its linear taper (indicated by 'LIN'). Unlike logarithmic (audio) taper potentiometers which change resistance exponentially, a linear taper ensures that the resistance changes at a constant rate relative to the angle of rotation. This is essential for welding controls, where the operator expects a 50% turn of the knob to correspond to a 50% change in the output setting, whether that be voltage, amperage, or wire feed speed. This linearity allows for intuitive and precise fine-tuning of the arc characteristics.

The unit is rated for 2.00 Watts of power dissipation. In the context of control potentiometers, this is a robust rating, indicating the component is built to handle the thermal loads associated with continuous industrial operation without drifting in value or failing prematurely. The 0.88-inch shaft length is dimensioned specifically to fit through the front panel chassis of supported ESAB models, ensuring the control knob sits at the correct distance from the faceplate. As an OEM part, it meets strict manufacturing tolerances for linearity, rotational torque, and contact resistance, ensuring that the restored machine performs exactly as it did when it left the factory.

Technicians replacing this part should verify the specific mechanical footprint and electrical values match the failed unit. The use of genuine ESAB parts like the 23608212 safeguards the integrity of the machine's control board and ensures compliance with the original electrical schematics.
