258058 - Miller 10 AWG Black Stranded Wire 600V 125C Replacement Cable

Premium Grade Internal Wiring for Industrial Equipment

The Miller 258058 Wire is a high-specification electrical component designed to meet the rigorous demands of industrial welding equipment. Engineered as a genuine OEM replacement part, this wire ensures that your Miller machinery maintains its original safety and performance standards. The wire features a robust 10 AWG (American Wire Gauge) conductor, which is essential for handling significant current loads without excessive voltage drop or heat generation. Its black insulation indicates its standard usage within power distribution or grounding circuits, adhering to common industry color-coding practices.

One of the standout technical characteristics of this wire is its impressive temperature rating of 125°C (257°F). In the environment of a welding power source, where internal components can generate substantial heat during long duty cycles, standard 90°C wire may degrade or become brittle over time. The 125°C rating of the Miller 258058 ensures long-term reliability and safety, preventing insulation failure that could lead to short circuits. Additionally, the wire is rated for 600 Volts, providing a substantial safety margin for most internal control and power circuits found in welding machines.

Flexibility is paramount when routing wire through the compact and complex chassis of a welder. This wire utilizes a 105x30 stranding configuration—meaning it is composed of 105 individual strands of 30 AWG wire. This high strand count provides exceptional flexibility, allowing technicians to route the cable around tight corners and through narrow conduits without stressing the copper conductor or the insulation. The Polyolefin (POE) insulation further enhances the wire's durability, offering excellent resistance to abrasion, chemicals, and environmental stressors commonly found in industrial workshops. With an outer diameter of 0.216 inches, it is precision-manufactured to fit standard Miller strain reliefs and terminal connections perfectly.
