There are some hoods that proclaim the ability to stay darkened even under the environment that welding of welding produces. Let me tell you from my professional experience as a long time welder, that when you use some of the advanced techniques that an expert welder uses, an auto darkening lens is not the best choice. I always find myself going back to the solid filter glass of a fixed shade. I personally like the shade. You will have to experiment for your own preference when it comes to the shade of your choice and what works best for you.
I try to use the auto darkening lenses as much as possible, especially when using stick rod processes. I welded on jobs where one simple accidental arc strike outside of the weld zone got you run off if detected by the welding inspector. Using a quick change lens can save you from an embarrassing and costly situation like that.
Let’s look at the solid lens first. Solid Lenses have been around since the time of torch and brazing were used. It was not the protective hood that was a staple of the mechanic/welder but the goggles and his lenses used to get a better picture of his puddle in the days of brazing and oxygen gas welding. The solid lens is cheap and efficient. It is not fancy but still very effective. I still find myself going back to the solid lens for certain welding processes. It works well with any basic hood and can be a good place to start for the inexperienced welder. Better yet, the welder that does not have much money when getting started.
