AUTO - DARKENING FILTERS
A Balanced Hard Hat Designed for Welders: ProTop
3M™ Speedglas™ ProTop System
The new ProTop combination hard hat, welding helmet, and auto-darkening filter system is especially designed for welders working in areas with overhead hazards.
The key to the Speedglas ProTop system is the exclusive pivot mechanism that connects the welding helmet to the hard hat. Traditional welding hard hats create a very high center-of-gravity when the welding helmet is raised; as a result, the user feels off-balance, and the leveraged weight may put additional strain on neck muscles. On the other hand, the ProTop pivot mechanism has two sets of axes: one to lift the welding helmet away from the welder’s face, and another axis to “nest” the welding helmet down low over the hard hat, in a balanced, secure position.
In addition to having a much more comfortable (lower) center-of-gravity, the nested welding helmet is much less likely to bump into obstacles as the welder moves around the work area.
