06-0400-51 - 3M Speedglas 9100 Replacement Headgear Assembly

Genuine Replacement Head Suspension for Speedglas 9100 Series

The 3M Speedglas 9100 Welding Helmet Headband Assembly (06-0400-51) is the definitive replacement suspension system designed specifically for the 3M Speedglas 9100 and 9100FX series welding helmets. As a critical component of the personal protective equipment ecosystem, the headgear serves as the foundational interface between the welder and their optical protection. Over time, daily wear and tear, perspiration, and mechanical stress can degrade the performance of the original suspension, leading to instability or reduced ergonomic support. This genuine OEM assembly ensures that the helmet retains its original safety ratings, balance, and comfort features, which are essential for precision welding operations.

This complete assembly includes every component required to overhaul the helmet's suspension system. It features the highly regarded Speedglas ratchet mechanism, which allows for micro-adjustments to the headband circumference, ensuring a secure fit that does not slip during overhead or out-of-position welding. The assembly also incorporates dual crown straps, a significant improvement over single-strap designs, allowing for precise vertical positioning of the helmet. This vertical adjustment is crucial for aligning the welder's eyes with the optical center of the Auto-Darkening Filter (ADF), thereby maximizing the field of view and optical clarity. The inclusion of friction adjustment knobs allows the user to customize the resistance when raising or lowering the helmet, preventing the 'helmet drop' phenomenon often associated with worn-out hardware.

Designed with the user's long-term health in mind, the 06-0400-51 utilizes an ergonomic geometry that avoids pressure on the sensitive arteries and nerves of the head. This attention to anatomical detail reduces fatigue and headaches associated with long shifts under the hood. The kit comes complete with a comfort head rest and all necessary mounting hardware, facilitating a quick and tool-free installation process. By utilizing genuine 3M spare parts, safety managers and procurement specialists ensure equipment longevity and compliance with manufacturer specifications.
