We do have to ensure that our welding helmet fits the requirements for viewing the Sun. A welding helmet can be a great way to watch the eclipse-but wait just a second. We have lots of tools, and know people who have a lot more tools! Most of us even have a welding helmet, or three, laying around.
SHADE 12 WELDING LENS FOR SOLAR ECLIPSE ISO
Can You Watch a Solar Eclipse with a Welding Helmet?ĭon’t let the high prices of the junk glasses and the ISO standards scare you away from the eclipse. Ensure that your glasses are compliant with the ISO 12312-2 safety standard. Even though it may appear dim, the remaining part of the exposed sun is enough to cause damage. Resist any temptation of viewing a partially eclipsed sun with unprotected eyes. Solar eclipse glasses from Phillips Safety Products use lens material certified to be shade 14. Use either solar eclipse glasses that meet ISO 12312-2:2015 requirements, or welding glasses with a shade level of 14. If you weld only a single material then a fixed shade lens will suffice. It depends upon your choice and comfort level of which welding process you will be using. Only the darkest welding glasses with a shade level of 14 will protect your eyes. Fixed shade lens or variable shade lens: The welding helmets which come with single shade that is pre defined are normally with 10, whereas there are variable shade helmets which can be darkened by a number of shades. If your glasses have any wordage such as “only use them for 3 minutes at a time”, these are outdated and should be trashed. Unfortunately, most welding glasses are unsuitable for looking at the sun.
You dont need a telescope to observe the Sun all thats required is an. Most observers prefer shades 13 or 14 the solar image through a shade-12 filter is uncomfortably bright. a solar eclipse If the glass is marked as OSHA shade number 12 or higher, its safe. Welders filters of shades 12 through 14 are popular and safe solar filters easily obtained at welding-supply outlets.
On the NASA web page above, they state: “If your eclipse glasses or viewers are compliant with the ISO 12312-2 safety standard, you may look at the uneclipsed or partially eclipsed Sun through them for as long as you wish.” This ISO standard should be in print on the glasses and easy to read. I once used a welders helmet to watch an annular solar eclipse.
