222326 - Miller 222326 NTC Thermistor 30K Ohm 34-Inch Lead

Miller 222326 Thermistor Product Overview

The Miller 222326 is a specialized NTC (Negative Temperature Coefficient) thermistor designed for precise thermal monitoring within industrial welding equipment. As a genuine OEM component from Miller Electric, this sensor is engineered to meet the exact specifications required for the safe and efficient operation of compatible power sources. The device features a nominal resistance of 30,000 Ohms (30K) at a standard reference temperature of 25 degrees Celsius, ensuring accurate feedback to the machine's control circuitry regarding internal operating temperatures.

This replacement part includes a 34.00-inch lead, providing ample length to route the sensor from the heat-critical component—such as a heatsink, transformer, or rectifier—back to the main control board or thermal management module. The insulated leads are designed to withstand the electrical and environmental conditions found inside welding cabinets, including exposure to heat and potential interference. Maintaining functional thermal sensors is critical for protecting expensive inverter components from thermal runaway and ensuring the machine operates within its rated duty cycle.

Industrial maintenance teams and repair technicians rely on authentic Miller parts like the 222326 to ensure repairs meet factory standards. Using generic sensors with incorrect resistance curves or beta values can lead to erroneous temperature readings, causing nuisance tripping or, conversely, failure to detect overheating events. This unit is supplied as a single package, ready for installation into the appropriate Miller equipment. Please verify fitment with your machine's serial number before ordering.
