599670 - ESAB 250k Ohm Linear Potentiometer 2W

Technical Overview of the ESAB 599670 Potentiometer

The ESAB 599670 is a precision linear potentiometer designed specifically for use within ESAB welding power sources and wire feeders. As a critical component in the control circuitry, this potentiometer allows for the accurate adjustment of variable parameters such as voltage, amperage, or wire feed speed. It features a resistance value of 250 kOhms (250,000 Ohms) and utilizes a linear taper, meaning the resistance changes at a constant rate relative to the angle of rotation. This linearity is essential for predictable and user-friendly machine calibration.

Constructed to handle the demands of industrial environments, this component is rated for 2 Watts of power dissipation. This power rating ensures the device can withstand the electrical currents typical of control circuits without overheating or degrading over time. The unit features a shaft length of approximately 0.88 inches, designed to interface correctly with standard ESAB control knobs and mount securely through the machine's front panel. Using genuine OEM parts like the 599670 ensures that the electrical characteristics match the original engineering specifications of the welding machine, preventing calibration drift and maintaining optimal arc performance.

Maintenance personnel and technicians should verify the resistance and taper requirements of the faulty component before replacement. This unit is identified by the markings indicating 250.0K and 2.00W. Proper installation requires soldering or connecting to the specific terminals as dictated by the machine's wiring diagram.
