A welding helmet is an essential piece of protective gear for welders. It offers safety and protection from sparks, intense light, ultraviolet radiation, and infrared radiation that is emitted when you are welding. While it may be black inside of a welding helmet when you place it over your head, the action of welding is easily seen once you strike your welding rod against the metal you are working with.What setting should you use for the lens shade?
The lens shade in a welding helmet is offered so that you can adjust the darkening effect to a shade that you prefer. If you prefer a darker effect, the setting can be adjusted to a higher number. Many individuals mistake this setting for the protection that is provided by a helmet. In reality, a quality helmet that has been well constructed will provide you with 100% protection from the harmful infrared and ultraviolet wavelengths that are present when you are welding.What is the difference between a variable- and fixed-shade helmet?
When you are working with different welders and types of materials, a variable-shade welding helmet will allow you to make adjustments to the darkening effect inside of your welding mask. If you don't use different welders or material and stay with the same welding process, a fixed-shade welding mask will offer you a sufficient amount of darkness.How does an auto-darkening welding helmet work?
An auto-darkening helmet will automatically create a black environment inside of your welding mask when an arc is initiated. The darkening response is powered via solar or battery power, liquid crystals, and light sensors. An auto-darkening welding helmet provides welders with both infrared and ultraviolet ray protective qualities at all times. The darkening mechanism yields more comfort when welding. The transition time for the filter to change from light to dark is typically in a range of 1/400 of a second and occurs after you start welding. This is fast when you compare the blink of your eye, which takes about 1/10 of a second.What advantages does an auto-darkening welding helmet provide?
The advantage of using an auto-darkening helmet comes into play for you or other welders who are constantly using welding equipment on a daily basis. Instead of having to flip your welding helmet up and down to see a project, an auto-darkening welding helmet automates the filter and light that come through the lens of the helmet.
