A welding lens includes a variable light transmission shutter that automatically darkens in response to light emitted from a source. An intensity of the emitted light is sensed by a photo-sensor located on a front face of the welding lens. Internal circuits located within a housing of the welding lens receive data from the photo-sensor and correspondingly darkens or lightens the variable light transmission shutter based on the intensity of the light. The housing is 50.80 mm in width and 107.95 mm in length to fit in corresponding welding helmets and the housing is made from stainless steel to reflect infrared radiation that would otherwise overheat the internal circuits within the welding lens.

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.

An anti-glare welding apparatus includes a switch and a controller. The controller is electrically connected to the switch. When the controller determines that the switch is switched from an OFF state to an ON state, the controller generates a welding helmet turn-on signal to switch on a filter of a welding helmet. The controller further generates a welding machine turn-on signal after a first delay time to switch on a welding machine. The filter of the welding helmet can be fully darkened during the first delay time when receiving the welding helmet turn-on signal, and the welding machine is switched on after the filter of the welding helmet is fully darkened. Therefore, there is no welding arc when the filter is darkening, and the eyes of the welding worker can be fully protected from damage.

The present disclosure provides a head-mounted welding mask, which includes a mask shell, a head-mounted mechanism, and a flip device, the flip device includes a knob which is connected to the mask shell, a link mechanism which is connected to the knob, and a base which is connected to the head-mounted mechanism, the link mechanism is disposed on the base, when the knob is moved, the knob drives the link mechanism to reciprocate in an arc, so that the mask shell flips relative to the head-mounted mechanism, and the barycenter of the mask shell moves into a predetermined range that is determined based on the gravity line where the barycenter of the head-mounted mechanism is located. The flip device changes the position of the barycenter of the mask shell through the movement of the link mechanism, so that the barycenter of the mask shell moves into a predetermined range that is determined based on the gravity line where the barycenter of the head-mounted mechanism is located. And reduces the pressure on welder's head after the mask shell is flipped up.

Welding cameras, welding helmets, welding masks, and associated display systems are described herein that utilize darkening or attenuating filters in conjunction with long-exposure imaging to capture flicker-free video of a welding process. Example embodiments include one or more of a darkening filter, an image sensor to capture long-exposure images as frames of a video, an optical image stabilization subsystem, a data storage to store video, and an electronic display to display the video. For example, captured images may be displayed on an electronic display within the welding mask without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different images to each eye of the operator to provide a stereoscopic video feed.
