A light blocking welding helmet having a helmet body with a shell having a head aperture produces an image from at least one (1) exterior camera within the helmet body. The helmet body includes an interior cavity containing an adjustable headband and an internal power source for powering the viewing screen and camera. The camera is mounted on the helmet body. Electrical circuitry is operatively connected to the power source, to the viewing screen, and to the camera such that the electrical circuitry causes the viewing screen to display the image produced by the camera. The image can be transmitted to a remote receiving unit where a weld can be monitored. Multiple cameras may be used and a control switch then selects which camera that will produce an image.

A welding helmet (100, 200, 300, 400, 500) having a filter arrangement is disclosed. The welding helmet is provided with a main filter (102, 202, 302, 402, 502) and at least one auxiliary filter (104, 204, 304, 404, 504) separate from and positioned next to the main filter. The at least one auxiliary filter comprises an electro-optic element (10, 20) adapted to attenuate the transmission of optical radiation incident on the auxiliary filter.

The present application discloses a wireless projector-type auto-darkening welding helmet comprising: a helmet housing; a headband structure for securing the helmet housing; an auto-darkening filter secured on the helmet housing; a wireless communication module; and a micro-projector which is data-connected to the auto-darkening filter and the wireless communication module, wherein when the auto-darkening filter is in a transparent state, the micro-projector is adaptable to project operating parameters of the auto-darkening filter and/or data received by the wireless communication module, as images, onto a plane in front of the welding helmet such that they can be watched by an operator who wears the welding helmet on his/her head. The present application also discloses a welding apparatus equipped with said wireless projector-type auto-darkening welding helmet.

A welding helmet includes a helmet shell and a lens device mounted on the helmet shell. The lens device includes a filter control module and a single LCD panel. The logic control module controls the transmittance of the single LCD panel based on a sensed light signal and a shading-level signal designated by a user. Therefore, when the welding helmet is operated in an environment having intense light such as a welding arc, the single LCD panel will turn dark and lower its transmittance to block the intense light.

Provided are a welding protector, a worker healthcare system, and an operating method of the system.

The welding protector includes a sensor generating a sensing signal obtained by sensing a wearing state of the welding protector worn by a worker; a memory storing at least one instruction; and a processor configured to execute the at least one instruction to generate a feedback signal, wherein the least one instruction includes information for identifying based on the sensing signal whether the worker is to perform a welding operation.
