Abstract
Improvements to helmet assemblies with flip-type welding visors are provided. In one embodiment, a return mechanism applies a predetermined force to a wireform spring. The return mechanism applies a force between a welding visor and a grinding shell, while concurrently reducing rotational forces needed to flip up the welding visor from the grinding shell. In another embodiment, a combination of an adjustable spring and a slide stop provides an adjustable stopping position for the wireform spring. The adjustable stopping position permits adjustable balancing of the forces that are applied to the wireform spring.
