We all know that the function of auto-darkening welding helmet is protecting our eyes from the harmful rays generated in the welding process. However, there are many low-quality kinds of auto-darkening welding helmets, which not only wastes your money but also poses many risks for your health.
To avoid these troubles, find out how to test auto-darkening welding helmet both before purchasing them and after.
The most crucial piece of safety gear for welding is an auto-darkening welding helmet. It switches from light to dark automatically.
But because of this, it’s essential to understand how to test your auto-darkening welding helmet.
It’s important to check your auto-darkening helmet is functioning before you hit an arc because if it isn’t, you might feel eye fatigue or welders flash that could harm your eyes.
There are four quick and simple ways to check the lens in your auto-darkening welding helmet, thankfully. Let’s look at it!
How To Test Auto-Darkening Welding Helmet?
Generate an arc
First of all, I need to notify you that there will be a high chance of a welder’s flash happening.
Thus, unless you are sure that the device will work, don’t operate the welding machine. The lens must be dark enough so that the spark won’t hurting your eyes.
You will know whether it is okay when you feel the appropriate brightness of the arc as well as see your weld more clearly.
Also, you should pay attention to the change in the shaded volume of the screen whenever you start/stop welding.
Use an infrared light source
As you will need to block both ultraviolet and infrared rays, checking a mask by using common IR light sources such as a remote control or a laser pointer is a good idea.
Create IR light from one of your devices and look at the light via the goggles. During that process, the mask has to remain in the dark status. If it doesn’t, you may need to have a higher sensitivity level.
Turn the grind mode off
In some helmets, there is a special grind mode that allows you to deactivate the sensors. If possible, try to use this feature to examine the lenses.
Utilize a torch striker
Welders often use this device to generate the oxy-acetylene flame.
Let’s make some sparks and see how the sensors work. A good auto-darkening welding helmet will change to its dark state whenever it detects the strong light.
Apply a heat source
Your welding helmet should have a cooling function to avoid being damaged by the heat. Put the device near a source of the heat (fire, for example) for a while to test how hot it can tolerate.
Stare at an extreme light source
The idea is simple. Wear the mask and gaze at strong light sources such as the sun or a high-voltage bulb. You can know whether your auto-darkening welding helmet works well in front of the luminous welding spark.
Check the batteries
Open the hood to find the batteries inside if possible. Next, take them out and test their metal contacts (with steel or aluminium, for example) to find out whether these batteries have trouble with any kind of metal.
Additionally, a handy battery tester will let you know whether the battery is broken or not.
How Long Do Auto-Darkening Helmets Last?
Your auto-darkening helmet’s lifespan is influenced by a number of variables, including how well you take care of it.
For instance, it’s unlikely to last very long if it’s going to be soiled and damaged while rolling around in the back of your vehicle.
The majority of auto-darkening helmets, however, should last you seven to 10 years with careful maintenance. The sensors, lens, and battery—all of which can be changed in certain helmets—are primarily responsible for this lifespan.
It’s important to remember that the lens or battery are typically the causes of auto-darkening helmet failure. These parts are frequently non-replaceable in low-cost helmets, so you’ll have to buy a new one.
The lens of your auto-darkening welding helmet is the area that is most susceptible. Therefore, you should always use caution while handling it. Avoid dropping or misusing your helmet to avoid damaging the lens and needing to replace it.
However, if you take good care of your helmet, you should be able to use the lens for a minimum of seven to 10 years before it has to be replaced. But bear in mind that only few helmets allow for lens replacement.
Therefore, it’s important to consider more than simply the lens shade range while picking a helmet. if you intend to often wear your helmet.
The kind of battery your auto-darkening helmet uses will also affect how long it lasts. Some batteries will require more frequent recharging and replacement than others.
Lithium-ion batteries, which can be recharged either manually using solar cells or by putting them into an electrical outlet, are frequently seen in auto-darkening helmets. The ones that use solar energy as a power source are the most practical and long-lasting.
Most non-replaceable batteries in auto-darkening helmets have a lifetime of roughly seven years. For this reason, purchasing a helmet with a replacement battery is typically a wiser investment. Many helmets are also solar-powered, which is often sufficient for more people and charges quickly.
Other Factors That Affect Lifespan
The longevity of your auto-darkening helmet can also be significantly impacted by keeping it without power for extended periods of time and exposure to low temperatures. In addition to the battery, the LCD reaction time is also prone to power loss.
The auto-darkening lens is affected by below-freezing temperatures, so it’s best to avoid storing your helmet in a garage, shed, or truck bed during the winter. The last thing you want to do is put the auto-darkening helmet in storage and limit the lens’s lifespan.
If the batteries in the helmet aren’t used for a while, they may potentially self-discharge.
To make sure that your helmet is still working well enough to protect your eyes, what you need is a monthly check on the device. And, here are what you need to concern.
Examine the batteries’ condition
To operate, your mask needs power.
If you have stopped using it for a long time, you may need to recharge it. If it is a solar-powered model, put it under the light for about twenty minutes. Then if it has a charging cable, plug it in.
Like any electronic tool, batteries also have a certain lifetime. Therefore, it is vital for you to replace them if necessary.
Make sure that the photosensors are clean and unbroken. Or else, they cannot detect the light and change the screen to dark mode.
Also, in case the auto-darkening filter does not work, you will need to buy a new one.

- How Does Auto-Darkening Welding Helmet Work?
Regardless of a helmet’s kind and brand, you always need to know how to test auto-darkening welding helmet before you use it.
Whether you have just bought a new helmet or possess a high-quality one already, bear in mind that a careful examination is never redundant.
Among the above ways, you had better apply the striker method as welding helmet vendors usually perform it in the shows to prove their products’ quality.
