¡¡¡¡The UV&IR Cut Filters manufactured by Xianglong Optics Co, Ltd could be used in producing light-controlling electric welding mask. They are vacuum-coated optical glasses. The UV&IR Cut Filters can effectively prevent the infrared ray and ultraviolet radiation that are harmful to LCD and welders¡¯ eyes. At the same time, they permit the light of visible area to permeate. The purpose is to ensure the clear eyeshot of welders and to avoid move lens by mechanical action. The UV&IR Cut Filters are the fruit of technology revolution in welding safety production field for the past ten yeas and are broadly used in domestic and overseas electric welding mask manufacturing field.
Comparing with the traditional black glass, the UV&IR Cut Filters have the following obvious advantages when used in producing light-controlling electric welding mask:
- more effectively protect welders¡¯ eyes
- automatically adjust darkness according to brightness arc
- make welders able to see clearly the welding surface and automatically adjust darkness
- capable of enhancing quality of jointing work and efficiency
- capable of saving material and lowering cost
- could be used when working in high altitude and make it not necessary to manually operate the welding mask
