238142 - Miller 50W 25 Ohm Wire Wound Resistor

Miller 238142 Resistor, Wire Wound Fixed 50W 25 Ohm 5%

The Miller 238142 is a high-specification electrical component designed for use within Miller welding power sources. This component is a fixed wire-wound resistor, engineered to handle significant power loads with a rating of 50 Watts. With a resistance value of 25 Ohms and a tolerance of 5%, it provides the precise electrical regulation required for the complex circuitry of industrial welding machines. Wire-wound resistors are known for their superior pulse handling capability and stability over time compared to other resistor types, making them ideal for the demanding environment of a welding shop where thermal cycling and electrical surges are common.

As a genuine Miller Electric OEM part, this resistor ensures compatibility with the specific mounting points and electrical parameters of your equipment. Using non-OEM components in power electronics can lead to calibration drifts, overheating, or premature failure of the circuit. The specifications indicate a robust design suitable for the internal environment of heavy-duty power sources, often used in control circuits or power regulation stages where reliability is paramount.

Technicians repairing Miller equipment rely on part number 238142 to restore factory performance. Whether used in the control board assembly, as a bleeder resistor for capacitors, or within the power regulation stage, this component meets the rigorous quality standards set by Miller. Its robust construction features a ceramic core and high-quality resistive wire, coated to protect against moisture, dust, and vibration—factors constantly present in industrial settings. Ensure your maintenance inventory includes genuine Miller parts to minimize downtime and maintain the safety certification of your welding assets.

When diagnosing electrical faults, a failed resistor often presents as an open circuit or a significant drift in resistance value. Replacing a damaged unit with the Miller 238142 restores the intended circuit path, allowing the welder to function correctly. This part is critical for maintaining the reliability and longevity of your investment in Miller welding technology.
