Welding helmets are worn to protect people from fire and sparks when welding. A person wearing a welding helmet is never in danger of getting burned by the flame, even if they’re right up against it. This is because a welding helmet has a special filter called a shade, which protects the welder’s eyes from the harmful light of the flame. Although many people know more or less what a welding helmet is and how it works, not many people know how to test one for functionality. What follows is a detailed description of how to test whether or not your welding helmet is working correctly.
Step 1: First, you must place your welding helmet on your head and be sure that all straps are secure and tight enough so that the helmet will not move or fall off while carrying out further checks. Next, you must make sure that the visor is down and that it won’t rise back up without you having to touch it.
Step 2:Once you have successfully achieved step 1, begin to check the filter itself. This filter is an essential element in a welding helmet as it determines what kind of light your eyes are exposed to. To check the filter of your welding helmet, hold it up against an object with a fluorescent light behind it, such as a lamp or lamp post. If the filter is working correctly, it should look just slightly tinted but clear enough that you can still see what’s behind the lamp. However, a faulty filter would be so dark that you wouldn’t even be able to see the object behind the lamp.
Step 3:After you have checked your filter, check your headgear. If you are wearing a helmet with a face shield (recommended for safety reasons), check that it is down by using an item that creates light like a mobile phone or watch with the backlight on. If your shade does not react in any way when held up to the light source, then there is no point continuing with this method of testing because this means that either something is wrong with your face shield or it is not down correctly. Now, if you are wearing a helmet that doesn’t have a face shield, then this is where things get tricky. First, get someone to hold up an object about 10cm away from your eyes (making sure it is right in your eye line). Then hold the welding helmet visor out of the way with your free hand and look at the object without using your visor. If the light filter is working correctly, you should see that there is no change in shading. If, however, the filter is faulty, then you should notice some difference in shading when compared with your visor down, even though they are both supposed to protect you from light.
Step 4:Now that you have successfully made all of the previous checks, there is one final step to check. This is the fact that the helmet fits snugly on your head. A way to test this is to use your hand as a guide and pull on the back of the helmet by twisting it slightly sideways. If you find that your helmet moves around on your head, then it probably isn’t tight enough.
Do Auto-Darkening Welding Helmets Wear Out?
The short answer is yes, but not with regular use. However, the lenses of all welding helmets will eventually scratch and get cloudy. It’s a simple matter to replace them, and they don’t cost much, so you could say that auto-darkening helmets wear out over time because they will need to be replaced eventually. However, this would be like saying that you wear out your car by driving it every day because, without regular use, the auto-darkening welding helmet will indeed get scratched and need to be replaced.
Do Auto-Darkening Welding Helmets Go Bad?
Many people, whether they are new to the profession or seasoned welders, ask this question. The short answer is yes. Auto-darkening welding helmet lenses become cloudy with regular use and can be replaced for relatively little money. It’s worth remembering that auto-darkening helmets are intended to protect just their ability to filter light, so even if they’re not used every day, they will still last longer than a traditional welding helmet that’s not auto-darkening.
Auto-Darkening vs. Passive Welding Helmet: Which Is Better?
An auto-darkening helmet is a safety device that offers several benefits over a passive, fixed shade helmet. Here are the significant differences.
Light Sensitivity: Passive helmets only become dark when a person looks through them and activates the shade. At the same time, auto-darkening helmets can also be triggered by the light coming from behind or from overhead. This helps prevent accidental flashes in areas where there isn’t enough space to move around freely. However, this feature does mean that users need to be familiar with their helmets so they can activate them when they need to work in lower light settings, such as placing internal tack welds inside body panels during assembly or repair work. Passive helmet lenses can be checked and tested to ensure that they are clear.
Safety: The passive shade helmet doesn’t protect the welder from close-up welding flash and other hazards. Auto-darkening helmets can be adjusted and maintained to work at close range.
Longevity: Auto-darkening welding helmets will eventually wear out and will need to be replaced. This process can take up to 10 years, and that’s only if the helmet is used an average of two or three times a week. A passive helmet can last longer if cleaned regularly, but it still won’t last as long as an auto-darkening helmet.
Price: Auto-darkening helmets are more expensive than passive helmets. However, auto-darkening helmets are more brutal to damage and may last longer. They may never need to be replaced.
