Welding Shields

3M welding guards, masks

In 1981, we revolutionized the world of welding with the first commercially viable, auto-dimming filter (ADF). Since then, the Speedglas ™ brand and the technology behind it have been the standard that everyone wants. The automatic dimming system allowed welders to significantly increase the comfort, productivity, and quality of welding work, due to the fact that it was no longer necessary to constantly raise and lower the welding shield in preparation for welding, in addition, this technology made it possible to inspect the weld immediately after disconnecting the welding arc. Today Speedglas ™ is the world’s leading brand of personal protective equipment for welders and an essential component of the 3M ™ line of protective equipment.

Auto darkening

The technology used in the 3M ™ Speedglas ™ welding filters provides instant (0, 0001 s) and uniform dimming of the filter in response to the welding arc. This allows the welder to work without hindrance without the need to raise and lower the welding shield, since the automatically dimming filter has excellent visibility and protection both in the darkened and non-darkened state. Even in the darkened position, the filter passes only visible light and reflects ultraviolet and infrared rays, the welder’s vision before exposure to light radiation. The use of automatically dimming filters allows you to increase welding productivity up to 20%.

Expiratory air

The unique expiratory air exhaust system used in the 3M ™ Speedglas ™ welding shields provides moisture and heat removal from the under-mask space and allows you to work comfortably for a long time without experiencing discomfort due to fogging and increased temperature in the under-mask space.
