The following operations require full face protection by using either a welding helmet or a hand shield:
Class 7B – respirator facepiece for non-ionizing radiation protection. Class 6B – face shields for non-ionizing radiation protection. Classes 3 and 4 – welding helmets and hand shields. Class 2C – direct / non-ventilated goggles with non-ionizing radiation protection. Classifications of common protectors for welding operations are listed below: Eye and face protectors should have distinctive markings to identify the manufacturer and their class. Each class is designed for a specific use. The standard is voluntary, so buyers should confirm that the helmet is ANSI Z87.1 compliant (indicated by appropriate labeling).The various types of eye protection are broken down into classes in the CSA standard Z94.3-15 "Eye and face protectors”. The standard requires that auto-darkening helmets provide full protection against both UV and IR even when they are not in the darkened state. In the United States, the industry standard for welding helmets is ANSI Z87.1+ which specifies performance of a wide variety of eye protection devices. In January 2004, 3M acquired all assets of Hornell, including the Adflo and Speedglas auto darkening helmets brand name and patents. The advantage is that the welder does not need to adjust the position of welding helmet manually which not only saves time but also reduces the risk of exposure to the harmful light generated by the welding process. With such electronic auto-darkening helmets, the welder no longer has to get ready to weld and then nod their head to lower the helmet over their face. In 1981, Swedish manufacturer Hornell International introduced an LCD electronic shutter that darkens automatically when sensors detect the bright welding arc, the Speedglas Auto-Darkening Filter. Finally, you will need that your helmet meets the location ANSI Z87.1 standard and choose a shade that is referred to for your task. Similarly, this number increases with an increase in amperage rating.ĭIN number 12 is ideal for arcs ranging from 160 to 200 amps, 13 for the range 200 to 240 amps, and for the welding over 250, a shade number of 14 is usually recommended. For a welding job dealing with arcs of the range 60 to 160 Amps, you should choose a DIN shade number of 11. The welder’s eyesight is also an essential factor here however, we suppose the results for ideal vision. According to OSHA, welding work ranging from 50 to 60 amps requires a shade number of at least 10. The shade of lens suitable for your job depends on the amperage rating of your weld. For example MIG and TIG welding are low-intensity processes, so a lighter lens shade will be preferred. Different lens shades are needed for different welding processes. In most helmets, the window may be made of tinted glass, tinted plastic, or a variable-density filter made from a pair of polarized lenses. Most welding helmets include a window covered with a filter called a lens shade, through which the welder can see to work. The modern welding helmet used today was first introduced in 1937 by Willson Products. #Welding lenses shade 14 skin#
In addition to the radiation, gasses or splashes can also be a hazard to the skin and the eyes. Ultraviolet emissions from the welding arc can also damage uncovered skin, causing a sunburn-like condition in a relatively short period of welding. Both conditions are caused by unprotected exposure to the highly concentrated ultraviolet and infrared rays emitted by the welding arc. Welding helmets can also prevent retina burns, which can lead to a loss of vision. They are necessary to prevent arc eye, a painful condition where the cornea is inflamed. Welding helmets are most commonly used with arc welding processes such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. ( December 2021) ( Learn how and when to remove this template message)Ī welding helmet is a type of headgear used when performing certain types of welding to protect the eyes, face and neck from flash burn, ultraviolet light, sparks, infrared light, and heat.
