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.

A laser protection device, in particular a laser protection helmet, includes at least one optical glare protection filter, which in particular has a nose cutout, further includes at least one sensor unit which is configured for a detection of a working state and for actuating, as a function thereof, a transmittance of the glare protection filter, and includes at least one shield unit which is configured to protect a face of a user and in which the at least one glare protection filter is fixedly accommodated, wherein the laser protection device further comprises at least one radiation protection unit, which extends around the glare protection filter and at least partially consists of a laser-absorbing, in particular metallic, material.

The present invention relates to a welding helmet including a wireless auto light shield part and a controlling method thereof. More particularly, the present invention relates to a welding helmet including a wireless auto light shield part capable of improving convenience of a welding operation, protecting eyes of a worker from direct light during welding operation, and preventing frost from being formed on the viewing window by shielding or opening a viewing window through elevation of a shield glass while automatically driving the light shield part in a wireless scheme by operation of a torch switch, and a method of controlling the same.

A personal powered air respirator, for example a welding or spraying helmet (10), includes a remote controller (30) for adjusting one or more operating parameters of the helmet and a means of displaying information regarding said parameter in, on or adjacent the interior of the vision panel (12) of the helmet. The invention allows for convenient adjustment in use. The remote controller is adapted to clothing, such as belt, glove or pocket, or may be incorporated in equipment for use with the helmet.

A welder protection device comprising a shell and a transparent front cover for protection of a wearer of the welder protection device, and an auto-darkening optical filter. The welder protection device further comprises a retracting mechanism arranged to move the optical filter optical filter from an active position to a retracted position and vice versa. In the active position, the optical filter lies inside the welder protection device and in the wearer's field of view, and in the retracted position the optical filter lies inside the welder protection device and outside the wearer's field of view.

Apparatus and methods are disclosed for the rapid and reliable replacement of protective windows of the shields and electric-arc shields. A locking device releasably connects the face shield window with the helmet or cap bracket.

A welding information providing device is proposed. The device may include a body provided to cover at least a portion of a worker' face and including a first region facing the worker' face and a second region located in a region opposite to the first region. The device may also include a camera unit located in the second region of the body and capturing a welding video to acquire a video frame. The device may further include a display unit located in the first region of the body and providing a video generated through the video frame.

A welding-type helmet includes a cover with a channel recessed from an external surface of the cover, the channel being configured to house a removable light source within the channel.

A welding protection device that includes a shield body, an automatic darkening filter insertable in the shield body, and a haptic sensing unit to sense a touch pattern occurring on the shield body or automatic darkening filter assembly. Upon sensing of a touch pattern, a user definable command is executed that can place the welding protection device in a specific operational state.
