OVERVIEW

Genuine Miller Replacement Hardware for Arc Armor Headgear

The Miller 257090 Arc Armor Hardware Kit is a critical maintenance component for the longevity and functionality of Miller welding helmets. Designed specifically for the Miller "Arc Armor" line, this kit replaces the mounting hardware that connects the headgear suspension system to the helmet shell. Over time, the friction washers and threaded knobs on a welding helmet can wear down due to the repetitive raising and lowering of the hood. This wear results in a loss of tension, causing the helmet to drop unexpectedly or fail to remain in the upright position.

This OEM kit includes all necessary components to refurbish the pivot points on both sides of the helmet. It is engineered to fit a wide range of Miller series, including the Digital Infinity, Digital Elite, Digital Performance, Pro-Hobby, Classic, and MP-10 series. It is compatible with Generation 1 through Generation 3.5 headgear systems. By replacing these components with genuine Miller parts, users ensure that the detent and friction mechanisms function as originally designed, maintaining the precise "nod-down" capability that professional welders rely on.

Installation is straightforward and typically requires no tools, allowing for quick repair in the field or workshop. The components are molded from high-durability industrial plastics designed to withstand the heat and rigors of a welding environment. Regular inspection and replacement of this hardware can significantly extend the service life of the entire welding helmet assembly.
