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.

Abstract: A protective helmet having a cover plate over a front vision area and a cover plate knock out assembly for moving the cover plate a predetermined distance away from the helmet so that a finger of a user can get behind the cover plate to enable its removal from the front vision area of the helmet. The cover plate knock out assembly comprises a step-shaped actuator element and a light blocking cover. The upper portion of the step-shaped actuator pushes the cover plate away from the helmet when the lower portion of the step-shaped actuator is pressed. The cover plate made of clear plastic includes a spring tendency when slightly compressed when attached to the helmet thereby pushing the upper portion of the step-shaped actuator into a resting position in the helmet.

The cover plate knock out assembly comprises a step-shaped actuator element and a light blocking cover. The upper portion of the step-shaped actuator pushes the cover plate away from the helmet when the lower portion is pressed towards the cover plate. The cover plate is made of clear plastic and has a tendency, when slightly compressed and attached to the helmet, to push the upper portion of the step-shaped actuator into a resting position in the helmet.

Abstract: A protective helmet having a cover plate over a front vision area and a cover plate knock out assembly for moving the cover plate a predetermined distance away from the helmet so that a finger of a user can get behind the cover plate to enable its removal from the front vision area of the helmet. The cover plate knock out assembly comprises a slide/pushbutton element and a light blocking cover. The slide pushes the cover plate away from the helmet when the push button portion is pressed. The cover plate made of clear plastic comprises a spring tendency when slightly compressed when attached to the helmet thereby pushing the slide into a resting position in the helmet.

Abstract: A welding machine having a first receiver for remote control of the operating parameters, a viewing module having a second receiver for remotely controlling the operating parameters of the viewing module, and a control module for controlling the operating parameters of the welding machine and the viewing module wherein the control modules and the viewing modules may be mounted in a helmet. A master control module is provided for remotely controlling a plurality of control modules wherein each control module controls a viewing module. Each pair of control module and viewing ,module controlled by the master control module may be mounted in a helmet.
