MAGICIAN PATTERN AUTOMATIC VARIABLE LIGHT ELECTRIC WELDING PROTECTIVE MASK (BLACK)

Main Features:
● Eye protection: double filter, to avoid the electric radiation and harmful radiation generated by arc ultraviolet, and injury on the eyes caused by welding light, to prevent the occurrence of electro-optical ophthalmia
● Facial protection: effectively prevent the splash of the operation, and harmful substances from the face, reduce the incidence of skin burns
● Respiratory protection: air flow, effectively reduce the release the damage caused by harmful gases and dust to the body, to prevent the occurrence of occupational pneumoconiosis diseases
● No battery needed, the solar charging system will charge the inserted battery automatically
● High-quality PP and fire retardant materials, can prevent resistance, anti-aging
● The auto darkening filter lens can prevent against ultraviolet, infrared, splash and welding radiation, avoid the side effect of the arc light on your face and eyes, it works the moment you start work with this advanced circuit design
● The streamlined design avoids the lens blur at low temperature because of breathing, and ensure breathe normally
● Sensitivity and delay time is adjustable
● It's a good partner for welders
