258347 - Miller 258347 Field Kit for 137901 Contactor Replacement

Reliable Power Control Restoration

The Miller 258347 Kit is a specialized field replacement unit designed to replace the 137901 contactor in select Miller welding power sources. Contactors are critical electromechanical components responsible for switching the high-current power required for welding operations. Over time, the internal contacts can wear, pit, or fuse due to the intense electrical arcing that occurs during switching, leading to machine failure or erratic arc performance.

This genuine Miller Electric kit ensures that your equipment is restored to its original operating standards. Unlike generic aftermarket replacements, this OEM part is engineered to handle the specific inductive loads and duty cycles of Miller welding machines. Installing the correct contactor is essential for maintaining the safety and longevity of your welder, preventing overheating and ensuring consistent arc starts.

Whether you are performing routine maintenance or an emergency repair, the 258347 Field Kit provides the necessary hardware to swap out the older 137901 unit efficiently. Trust in genuine Miller parts to keep your industrial operations running smoothly with minimal downtime.
