Double-headed Eagle Pattern Automatic Variable Light Electric Welding Protective Mask

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 in 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
● 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
