Abstract
Welding helmets, systems, and kits providing real-time fume exposure monitoring and warning capability during an arc welding process. A welding helmet configured to protect the head of a user during a welding process is configured with an intelligent warning apparatus and an air-sampling pick-up and output port. The air-sampling pickup and output port connects to a proximal end of an air sampling tube for sampling breathable air within the welding helmet, and a distal end of the air-sampling tube connects to an air-sampling in-take port of an external aerosol monitoring device. The intelligent warning apparatus communicates with the aerosol monitoring device to receive air sample output data from the aerosol monitoring device, and to process the air sample output data to generate warning data and/or warning signals based on preset exposure level set points and/or exposure warning operating modes.
