The revolutionary 3M™ Speedglas™ 9000 helmet features aerodynamically designed exhaust vents that help to remove axhaled air.
Welders experiencing lower humidity, less heat, and reduced "stuffiness". The welder's natural breathing action directs the exhaust airflow; no moving parts are involved. Fresh, incoming air is not drawn through the special vents; instead, it chooses the path of least resistance — the area around the welder's neck, which is typically further away from the smoke plume.
Increased Ease - Of - Use
We've eliminated those time-consuming lens fastener screws! Now you simply snap-off the helmet's front panel and squeeze two locking tabs together to quickly remove the lens casette. Changing the inner and outer protective lens plates has never been easier or faster!
Speedglas™ 9000 construction : Note the aerodynamic exhaust vents that are located directly behind the front silver panel. The patented helmet is extremely comfortable, weighing only 17.4 ounces (includung lens) and has excellent ballance. Its narrow wodth is ideal for welding in tigh spots. Chemical resistant and extremely durable.

Introduction To Auto - Darkening Welding Fiters (ADF's)
Safety Products That Increase Your Performance
Now welders can always see their work, at comfortable light levels, with constant eye and face protection. Speedglas™ lenses turn dark the moment an arc is struck and transparent again when welding stops-all the time with full UV / IR protection. Auto-darkening eliminates the neck-strain of "helmet flipping" while greatly increasing the accuracy of electrode placement.
This, in turn, reduces the need for grinding and rework. In addition, welders can get into tight, cramped spaces with full protection and have a clear view-in effect, making extremely awkward welds a lot easier.
How It Works
Each Speedglas™ lens is a laminate of seven different layers : a UV / IR filter, three polarizers, two liquid crystal elements and a cover glass. The UV / IR filter continually blocks harmful radiation, whether the lens is ON, OFF, light or dark. Aided by surfacemounted electronics, the proprietary liquid crystal elements act as shutters that detect and react to the welding arc by instantly shading the lens.
Fail-Safe Darkening
When you pick up an unenergized Speedglas™ lens, it is in an intermediate dark shade; you must turn it ON to make it go into light state. If anything catastrophic happens to the lens, it simply defaults back to the darker intermediate OFF shade. As mentioned above, UV / IR protection is always present.
