To learn more about the factors when choosing the best welding helmet with auto darkening technology, let’s move to the customers’ guide, where we share answers and hints on the most frequently bothering issues when it comes to the purchase.

Customers’ Guide

What do you frequently come across when you plan to buy a welding helmet? Most commonly, it is the question of – how much and what interesting perks to look for. Let’s understand.

A welding helmet is actually protective equipment when doing welding work, as it helps protect you from facial injuries and minimize such a terrible-to-experience feeling as an eye strain.

In the market, it comes in 6 varieties, including passive, solar-powered lens, battery-powered, fixed-shade lens, variable-shade lens, and auto darkening helmets, and one chooses the preferred one based on his most performed works.

Auto darkening welding helmet works by performing a certain function with the help of filter lenses, which, when activated, turn on shade 3 filter. What do they do? When you do welding work, you are likely to see sparks and bright colors, so the helmet will adjust the lens in a way you won’t experience pain in your eyes or discomfort.

Or, to explain to you using understandable terms, it may resemble the functionality of sunglasses that you put on while lying on the beach to avoid direct sunlight. 

Auto darkening filter itself may understand what type of shade is required and activate it for your needs. Beyond that, an auto darkening welding helmet might be the right purchase if you want to save your time during working, as you do not need to remove the helmet to see objects.

Auto-darkening feature (1)

Looking further, it is interesting to know that with the help of a helmet, you may even see an eclipse, so it is a kind of equipment that may fit many functions rather than welding only.

Based on the above products, you might see certain features available in auto darkening welding helmets, so let’s decide on which one of them you should concentrate the most.

How to Choose the Best Auto Darkening Welding Helmet? 

The choice of auto darkening welding helmets starts with the understanding of the material they are made of. You may either speak to your colleagues or friends asking for recommendations or trust customers’ feedback. Below, we mention standard materials used for creating comfortable shells.

Materials of Helmets

The majority of modern welding helmets come either in plastic or Nylon. When it comes to plastic, you might understand that the quality is expected to be above average, but the price might be lowered compared to other shell materials. Nylon is a synthetic polymer known for its lightweight and impressive durability, so such a welding helmet may withstand many extreme conditions.

Note, plastic materials are not the best choice for welding works where extreme hot conditions are involved, though it may differ from manufacturer to manufacturer. When choosing the helmet, ask the seller about the maximum temperature limit.

Some helmets may also be found made with Noryl, and Amodel, which are more expensive, and usually are used for high-professional equipment. Beyond that, they are expected to serve one longer than Nylon and Plastic together.

So, what to choose? The best recommendation falls for Nylon, as auto darkening welding helmets made with it may be found both with low and high prices. Beyond that, Nylon shells may be a good fit for new workers who just try the equipment out to find the golden mean.

Understanding Auto Darkening Feature?

Auto-darkening technology actually says itself – it darkens the environment you see from the helmet; however, what stands behind its functionality?

This feature works with the help of:

UV/IR filter

A UV/IR filter is actually a group of layers in charge of protecting one against infra-red and ultraviolet rays. The filter comprises a thin glass layer alongside additional metallic layers, which, in turn, have 5 silver layers, and 6 aluminum oxide layers.

It sounds a little bit complicated, but you do not need to deal with it much, as these parts are mostly the areas of interest of standardization committees. So, the metallic layers serve as protection against infra-red and heat damage caused by extreme hot conditions involved in welding works. To filter ultraviolet, there is a combined work of metallic and polarization filters. 


Polarization filter

A helmet contains a polarization filter, which helps fight ultraviolet as well as bright light occurring during the welding works.

Liquid crystals cell

These elements help a helmet bend light. You may adjust the filtration of crystals to not refract the light as well.

Arc sensors and light sensors

Both sensors are in charge of identifying the actual intensity of light and then darken the lens. They may be many in different helmets.

If you are interested in getting many sensors to enjoy the highest comfort during the works, the recommendation may fall for the Lincoln Electric Viking 3350 welding helmet.

What’s next? Auto darkening technology lies in shades as well.


Shades make the welder’s work faster, more productive, and easier, as one does not have to remove the helmet all the time. When a helmet is not activated, a lens automatically applies 3 or 4 shades, meaning that a welder may see everything as without a helmet.

Grinding mode and multiple shades

To make it understandable, a welder feels that he still wears a helmet, but a sensation is similar to wearing a pair of sunglasses.

To activate the lens, the welder should light the arc, then the helmet identifies the arc, and the shade changes its range from 3-4 to 10-13. The auto darkening happens immediately, and you won’t harm your eyes.

Size and Weight

Here comes a size and weight matter, though, you should choose a welding helmet only based on your feelings when you wear it. The best decision is, of course, buying helmets in stores where you may try them on your head.

The product catalog mentioned above dealt with helmets that have been tested for convenience in terms of weight and size as well. Testings have occurred on medium-strong physique people. So, there are 5 helmets, which are light to medium to heavy in weight.

Note, it also depends on the material used, whether Nylon or Plastic was involved. Moreover, understand that the more interesting perks you look for, the more possibility to put a “heavy machine” on your head, strange it may sound.

Usually, the weight ranges from 1.4 to 4 pounds (630 g to 1.8 kg). As for size, it is dictated by your comfort as well, but you may check the approximate measurements or else called calculations by looking at the above-mentioned helmets. There are two light ones, and 3 medium to strong in weight helmets.

Convenience of Helmet

The main convenience of the auto darkening welding helmet is related to shade again, as it helps minimize timing for wearing and taking off the helmet and avoiding harmful eye strain. Other convenience points might be related directly to knobs, which help adjust the helmet on your head.

Comfort of the helmet

If trying out the helmet at a store, try to adjust the knob until a helmet sits conveniently. If a helmet does not have any knobs, check whether there is a smooth ratchet system that allows a helmet to fit ergonomically. The last feature is available with 3M Speedglas 9100.

Switching Speed

Switching speed works by indicating a welder how long it takes the lens to switch a shade once the arc is activated. Logically, the faster it works, the less harm you experience on your eyes.

Before, the average switching speed of welding helmets was quite good when it reached 1/3.600 a second, while today, such speeds won’t boost the welder’s productivity. The best switching speed ranges between 1/10.000 and 1/25.000, as you do not even spend time waiting for it to be activated.

Switching speed

What About Battery?

There are a few power sources to choose from when deciding on auto darkening welding helmet, including:

  • lithium;
  • rechargeable;
  • changeable;
  • solar-powered.

Depending on the battery choice, there is different durability. For instance, replaceable batteries may last longer, while non-replaceable batteries may expire in a few years. Beyond that, solar-powered helmets may be kind of inconvenient, as they should be frequently placed under the sun before welding works.

Some helmets may also combine lithium batteries with solar ones. If you are not sure what may last longer, go for this option.

Note, there are manufacturers that complicate the replacement of batteries, as you should buy them only from them. If you look for a helmet with no additional headache afterward, go for products that come with standard-sized batteries.

Standards for Welding Helmets

Let’s also cover the standards for welding helmets. Today, it is ANSI Z87.1 – 2003. If, for you, these letters and numbers do not say anything, the manufacturers must comply with them strictly, though there are many parties that do not even care about any rules. So, what does this standard stand for?

The standard means that a manufacturer should organize and then demonstrate the laboratory tests, which confirm that a helmet functions well and specifications for switching speeds and shades comply with the safety standards. All in all, a helmet should work smoothly and should not evoke any risks when using it.

When buying a welding helmet, ensure a seller may provide you with a photo of helmet packaging, and check for ANSI Z87.1 – 2003 standard on it. If you buy it at a store, it is easier, as you may directly look at the packaging or ask the store worker about supporting documentation or licenses.

What Works Should a Welding Helmet be Fit For?

Auto darkening welding helmet should fit many welding works, depending on your needs; however, most of the modern products perfectly deal with:

  • Stick or else called shielded metal arc welding;
  • TIG uses Tungsten Inert Gas;
  • MIG uses Metal Inert Gas;
  • Flux-Cored welding uses a shielding gas;
  • Gouging is the removal of weld metal and base metals;
  • Grinding or polishing of surfaces;
  • Plasma cutting;
  • Oxy-fuel cutting.

Some helmet models may deal with all these works; however, you should pay attention to the material used for the shell, as some helmets won’t withstand hot working conditions.

Besides, do not look for every feature in one helmet if you hardly deal with one welding job. By following this strategy, you may only spend a lot of money and get a product, which functionality you won’t even experience in full.

Step-by-Step Instructions on Choosing Auto Darkening Welding Helmet

Struggling to start your welding helmet shopping? Follow the next steps:

  1. Decide on the money which you are ready to spend on a welding helmet. You don’t need to go for the most expensive one straight. Choose what features you would like to see in a helmet, and only after, base your choice on them. Fewer features, less money you spend;
  2. Understand what welding works a helmet should be capable of, including MIG, TIG, Stick, among others. Do not try to look for a helmet that may perform all tasks, as the price will be high again. Helmets of MIG, TIG, and STICK capabilities are standard and won’t cost you much;
  3. Learn the range of shades with a chosen helmet – the standard range is 8 to 13; however, you may have other preferences, so decide on them;
  4. Learn switching speed, and soberly estimate whether it is enough for you to perform welding works productively;
  5. Decide on the battery. The best recommendation is to choose a combined one where lithium and solar-powered ones perfectly engage and provide you with the durability of works;
  6. Read the customers’ feedback on one or another helmet, as this section may tell you a lot in terms of real experience with a product but remember that some of them may be paid for.

Last but not least, try to choose a helmet, which comes with an extended warranty. Most above-mentioned top picks come with a 3-years warranty, so you may try a helmet out and then decide whether it fits your requirements, needs, or type of work. If there is no warranty, you may greatly risk buying a helmet, as the reparation services of such equipment will ask you literally to throw money down the drain.
