The present invention discloses a glare shielding device. The glare shielding device includes a microprocessor for controlling an activation time and a driving time of a liquid crystal panel. The microprocessor generates an activation control signal of a liquid crystal activating portion, a driving control signal of a liquid crystal driving portion, and a power off control signal in response to a simultaneous detection of a welding light and a high frequency generated during a welding process. The liquid crystal activating portion becomes a floating state in a standby mode and activates the liquid crystal panel using a minus voltage between a high voltage and an activation voltage. The liquid crystal driving portion becomes a floating state in a standby mode and drives the liquid crystal panel in response to the driving control signal.

A method and system for controlling ventilation in a welding helmet is provided. The invention may be adapted to a wide variety of system types, and may reduce or eliminate the need for a shroud or barrier around the head and neck of the welder, of the type used in PAPR systems. The airflow system includes forward and rearward air streams, directed onto the face of the welder, onto the top of the head of the welder, and toward the back of the head of the welder. The air streams help to cool the welder, provide a fresh source of air for breathing, and create a positive pressure system that reduces or excludes entrainment of contaminated external air into the forwardly directed air flow. Certain embodiments may include streams that are filtered, split or redirected via deflectors and conduits to achieve the aforementioned goals.

A welding helmet having an auto-darkening welding filter comprises a viewing module and a control module attached to the helmet separate from the viewing module. In a first embodiment a control module is attached to a side of the welding helmet having a pair of variable resistor shafts extending through the side housing of welding helmet for adjustment of the auto-darkening viewing module by a user without removing the welding helmet from in front of the user's eyes. In a second embodiment the control module is attached to the inside of the helmet below the auto-darkening viewing module, and the control module comprises switches integrated on a surface of the control module which are operated by the user.

An airflow system is provided for a welding helmet. The airflow system includes an air intake with a filter, a blower, and a battery mounted to the rear of headgear for a welding helmet. A manifold wraps around the side and front of the headgear and directs air from the blower to the front of the headgear. The manifold includes a lower vent for directing air onto a user's face and an upper vent for directing air over a user's head toward the rear of the headgear. The vents are intended to create positive pressure to impede the entry of unfiltered air into the user's breathing zone. The manifold further includes a portion of flexible tubing for adjusting the size of the airflow system in conjunction with adjustment of the headgear diameter. The airflow system generally conforms to the structure and shape of the headgear to maintain a location close to the user's head.

A welding helmet having a headband that fits upon a head of a welder, and a face shield with a viewing port having a light filtering window that pivots on the headband between a raised up non-shielding position and a lower down shielding position has an automatic lighting system with a power source component secured to a interior bottom surface of a top portion of the face shield, and an illumination component secured to a top exterior surface of the top portion of the face shield for lighting a work area outside the helmet. The energizing of the lighting system is responsive to the position of the raising and lowering of the face shield of the helmet so as to permit the welder to better perceive his/her surroundings.

A personal safety protective device that includes a lens and a support structure onto which the lens is secured. The lens includes a substrate and a hard-coat layer located on the substrate of the lens. The hard-coat layer has a low surface energy outer surface that is derived from a) an additive that includes at least one of i) a perfluoropolyether urethane that includes hydrolysable silane groups, and ii) an acrylate polymer that includes at least one perfluoropolyether moiety and at least one hydrolysable silane group, and b) a silsesquioxane-based hard-coat composition. The provision of such a lens on a personal safety protective device enables the lens to be durable to abrasion and to be easily cleaned without use of solvents that could shorten the service life of the lens.

A welding helmet includes a helmet body for covering the face of an operator, an opening in a front surface of the helmet body, a cartridge for protecting the eyes of the operator from light generated during a welding operation, and structure including hooks projected from an upper side of the opening in the helmet body, pressing projections projected from both sides of the opening in the helmet body, hooking projections projected from an upper side of the cartridge to engage with the hooks, and fitting projections from both sides of the cartridge to fit to the pressing projections, the aforementioned structure removably engaging the cartridge to the helmet body. Fumes generated upon welding or cutting are prevented from directly flowing into the helmet body and injurious light generated upon welding is blocked. The cartridge can be readily removed for repair or replacement.

Arc welding systems, methods, and apparatus that provide dual-spectrum, real-time viewable, enhanced user-discrimination between arc welding characteristics during an arc welding process.
