How to choose the right welding helmet

Chameleon welder mask - how to choose the right one (our rating of masks)?

When working daily or frequently with a welding machine, eye protection becomes a top priority. Standard shields or glasses do not provide much comfort and ease of use and are incomparable to a professional chameleon mask. However, not all helmets of this kind are equipped with truly working eye protection. Let's look at what a chameleon welder's mask is and how to choose the right one among the variety of models presented.

Traditional welding protection and chameleon mask: comparison

The appearance of the classic welder's mask for eye protection occurred about half a century ago. The basis of protection here is a fixed light filter, which was initially attached to thick skin and then to a plastic shield.

Such a mask provides full eye protection during welding, but is not suitable for long-term work with a welding machine and cannot be classified as a professional welding mask.

Let us note the main disadvantages of the classical defense:

• The light filter is not dark enough, which does not block all ultraviolet rays generated during the welding process;
• The mask is uncomfortable for long-term use. She is massive, heavy, clumsy;
• The viewing angle is small.

Unlike a standard welding mask, Chameleon allows you to adjust and automatically darken light filters.

The name of this protection was given because of the special properties of the light filters used in its creation to independently change color under different conditions. Such glass with smart dimming is many times more efficient than standard glass for welding shields. This gives great convenience in work: the mask does not require removal to check the completed seam in accordance with the requirements of the welding process.

The Chameleon welding helmet is equipped with a regulator, the functions of which boil down to the following factors:

• Automatic filter change;
• Automatic adjustment of glass darkening level;
• Filter switching step arranged in a convenient scheme;
• Perception of the welding arc and the ability to adjust its perception.

The chameleon welding helmet is equipped with a liquid crystal display, which is powered by a solar or conventional battery. Sensors are installed near the lens, which are responsible for controlling the electric arc.

At the moment when welding is not performed, all filters are turned off and the welder is able to see his work without having to remove his helmet. As soon as the arc is ignited, the sensors are activated and instantly darken the screen with filters, preventing harmful ultraviolet radiation from entering the eyes.

Additionally, the mask is equipped with a protective coating that protects vision from dangerous radiation even when the filters are turned off.

Choosing a chameleon welder's mask is a responsible undertaking, since the welder's vision and comfort in his work are at stake. Let's look at the main criteria that are important to note when choosing, and provide a detailed plan on how to choose a chameleon welding helmet.

The most important and central element is the light filter. The marking of light filters is carried out according to the European standard EN 379, followed by four numbers separated by a fraction. Let's look at what each of them means:

1. The first number indicates the optical class to which the filter belongs. This figure gives an idea of ​​how clearly objects will be viewed through this filter. The best value is 1. Higher values ​​will cause the welder's eyes to tire quickly.
2. The second number gives an idea of ​​the filter's ability to scatter light. To put it simply, it is transparency. The higher the number in a given position, the cloudier the image will be.
3. The third number gives an understanding of how evenly the filter darkens. Now this parameter is designated as SHADE or DIN, which is a modern analogue of the older designation C 4-7.
4. The last position indicates the degree of darkness depending on the angular position, limited to 15 degrees.

Thus, the lower the number in each position, the better and more reliable the filter. Ideally this looks like 1/1/1/1.

Here are some tips on how to choose the right helmet based on the light filter and which one is better to choose.

• The quality of the filter must be confirmed by a special certificate;
• It is more advisable to choose helmets in which it is possible to replace the power supply. There are a number of products in which, after their service life has expired, this is not possible and you have to buy new protection;
• An important point when choosing a light filter is its response time. When choosing a helmet for home use, an interval of one hundred microseconds is sufficient; professionals are recommended to choose instances with a higher speed;
• The presence of multiple sensors increases reliability and eliminates the possibility of opening filters during operation;
• Changing shades in a quality product always works smoothly, without jerks. This does not interfere with work and allows you to focus on the quality of work performed.

General selection criteria

In addition to assessing the quality of the light filter as the main and central element of the mask, it is important to evaluate other important nuances of the Chameleon welder’s mask. Let's see how to choose protection based on other parameters:

• Manufacturer. It is important to study all the information provided about the product by the manufacturer - from information about the filter to the warranty period. The absence of this data should raise serious doubts about the quality of this product;

• Before choosing a welding mask, you need to decide on its type. The light filter for working with an argon-arc welding machine is universal and suitable for semiautomatic devices and electrodes;
• The dimensions of the glass are important, as this directly affects the welder’s visibility. However, it is worth remembering that large light filters are more fragile and require very careful handling;
• The temperature range of these helmets varies from +100 to -5°C. At lower temperatures, the response of the sensors slows down, which makes working in a helmet less safe and comfortable. This is a feature of the Chameleon welding helmet from any manufacturer. This is important to know and consider before choosing one;
• Important points are the appearance of the helmet, whether it has a tax collector, and neck protection. Before purchasing, it would be a good idea to try on the protection and evaluate the comfort of wearing it. It should not fit too tightly to the head;
• An important criterion when choosing is the weight of the product. A heavy helmet is unlikely to provide pleasure from wearing it for a long time.

Famous manufacturing brands

At the end of the review, we present the most popular Chameleon helmets:

• Products that meet all safety requirements are produced by the Chinese brand Tecmen, which is confirmed by its DIN Plus certificate. Some welders note that, with the highest quality, the protection of this manufacturer may cause some delay during the operation of the light filter and is not immune to spontaneous filter reset;
• High-quality chameleons are guaranteed to be produced in Europe, which is confirmed by their consistently high price;
• Russian-made products, in particular Svarog and Resanta, are noted for stable quality. Users note that domestic masks can open spontaneously when welding with an argon arc;
• Despite high sales, we do not recommend Korean helmets, since their filters most often crack or become stained.

The choice of welding protection is a key point when organizing welding work. The quality of the chosen mask depends on:

• Safety of vision and eye health of the welder;
• Quality of work performed;
• Convenience and comfort when welding.

The listed parameters are fully consistent with the modern type of welding helmets, which, thanks to self-adjusting filters, are called Chameleon.

The choice of such protection should be based on the quality criteria of the light filter used in it, and also take into account the availability of certification, the possibility of replacing the power supply, the dimensions of the mask and the good reputation of its manufacturer.

The welder's mask "Chameleon" is an automatic protection of the eyes of workers from unacceptable radiation during welding work. A light filter, powered by a small battery, almost instantly changes light transmission when an electric arc is ignited, protecting the eyes from unwanted radiation.

The Chameleon filter is an optical device with liquid crystal elements and polarizing films that do not transmit the ultraviolet and infrared parts of the spectrum.

Characteristics

• Adjustments . There are external and internal. A good mask has settings for arc radiation and a delay time at the end of the welding process. External adjustments allow you to change parameters during work;
• Cheap models behave unstable, especially during tig welding (they open). It is checked in this mode. In other modes it will work satisfactorily;
• Blackout . Using Speedglas and Balder filters you can achieve good values;
• The transition time from one state of the light filter should not exceed 1-2ms. The time to change state increases in winter. This must be taken into account when working.
• Optical values . Example (abstractly): 1/2/3. 1 — transparency coefficient; 2 - radiation scattering; 3 — level of dimming uniformity.
• Availability of infrared arc detection sensors . More sensors reduce the likelihood of the filter opening.
• Visible area . With larger sizes, greater ease of use.

A welder's mask is a necessary item. But if you buy the “wrong” mask, you can seriously harm your own health. We select a welding mask with the help of a specialist.

We study what a “chameleon” filter is and its purpose, look at the regulators and additional functions of various models of welding helmets.

Buy a Chameleon mask

• Immediately discard Chinese and Taiwanese goods. Here, the protection will be triggered when an arc occurs with a delay, and during operation the filter may open;
• Domestic Chameleons are good, but they do not like argon welding - they open spontaneously;
• Korean OTOS. There are problems with mechanical strength. They crack and stains appear. May be under the French brand GYSMATIC;
• We choose a European manufacturer. A package of three or more layers of liquid crystals will ensure the protection and health of your eyes.

The batteries must be quickly replaceable so as not to change the filter itself. With solar panels, their area is important.

The operating time of the filter depends on this.

When choosing a mask, you must remember that work productivity depends on quality. Here price comes last. An international certificate is required.

How to choose a welding helmet, characteristics and recommendations

Enter your request to start the search.

Electric welding work is an integral part of almost any construction or repair process. In this article we will tell you how to choose a welding helmet, and which one to choose - a regular one or a chameleon. Characteristics of chameleon welding helmets, selection of protective glasses for welding masks.

Half a century ago, when the first welding helmets appeared, there was no question of how to choose a welding helmet. The products were made from natural rough leather, which was later replaced by plastic masks. The filters in them coped with their task only partially. In this regard, they are not very suitable for long-term, professional welding work, but they are quite suitable for one-time and short-term welding work.

The main disadvantages of classic welding helmets:

Protective glass for a welding helmet provides little protection against ultraviolet radiation;

Generally poor ventilation;

Inconvenient to use.

There is also an advantage, although one thing is the low price (300-500 rubles).

Shield for welding work

Welding shields are perhaps the simplest and cheapest (RUB 150-200) method of protection during welding. The welding shield has advantages - during work, the welder can simply move it away from his face to see the result of his work.

By the way, some models are also equipped with hand protection from sparks. But this is where the advantages of the welding shield end.

Disadvantages: the need to hold the protective shield in your hand - for a large volume of work this is a significant problem, significantly increasing the operating time.

However, for small and one-time work, the shield is ideally suited, which is why very often inexpensive household welding machines are equipped with such protective products. Shields also have another big drawback - protective glass for a welding helmet (with the exception of models with chameleon filters) provides insufficient protection.

Welding helmet "Chameleon": advantages and disadvantages

Welding helmets "Chameleon" have replaced classic masks and shields, and are a new generation of protection during welding work. The main difference between “Chameleons” and the classics is the use of an innovative light filter that provides reliable protection for the welder’s eyes.

The glass for Chameleon welding helmets is made using new liquid crystal polarization technology. Of course, when the question arises which welding helmet to choose, many experts answer: undoubtedly, “Chameleon”. And that's why.

Characteristics of welding helmets "Chameleon"

“Chameleon” can be safely classified as a professional welding helmet, as it ensures comfortable and safe work for the welder even during long-term work. 

The main advantages of the “Chameleon” masks are the automatic darkening of the light filters, that is, to adjust the darkening, the welder does not need to remove the mask to control his work.

In fact, the mask itself received the name “Chameleon” because of its ability to change the color of the lenses in welding and pause modes.

The chameleon welding mask is equipped with a liquid crystal screen, where liquid crystal layers alternate with polarization films, which is powered by batteries or a solar panel. It is recommended to choose masks with regular batteries or a rechargeable battery, since the solar battery will quickly lose charge in cloudy weather or in the absence of sun (when working indoors).

In addition, the chameleon screen is equipped with filters against infrared and ultraviolet radiation. Also, a modern mask has sensors in its design that allow you to control the arc.

The protective screen (glass) of the “Chameleon” welding helmet operates as follows: as soon as the arc is ignited, sensors are activated that instantly darken the screen, protecting the welder’s eyes, and layers of filters do not allow ultraviolet and other harmful radiation to affect a person.

When choosing a “Chameleon” welding helmet, you should pay attention to the main characteristics: the response time of the light filter, it should be below 1 millisecond. Please note that when operating in severe frost, the response time may increase, but only slightly.

Light glass filters for welding helmets “Chameleon”

Special standards have been developed for European consumers, in particular for light filters there is the EN 379 standard, which describes all the characteristics that light filters for welding helmets must meet.

So that the buyer understands what he is purchasing, the mask is marked with indicators written approximately in the following form: 1/1/1/2. What does this marking mean?

The first number is the optical class of welding lenses. That is, this is the level of accuracy of transfer of welded parts and the level of distortion. The lower the number, the more accurately and with minimal distortion the image is transmitted.

The second number is light scattering, that is, an indicator of the level of transparency of the lens. Number one is the smallest and best indicator; the higher it is, the worse it is for the welder’s eyes, especially if you have to weld small parts.

The third number is the homogeneity of the lenses of Chameleon welding masks. In other words, this is the uniformity (homogeneity) of applying the darkening layer to the surface of the lens. Of course, the better this is done, as evidenced by the minimum number “1,” the better.

The fourth number indicates the level of darkness at different viewing angles. High class 1 DIN, low class 2 DIN.

Shade level of welding helmets Chameleon

A professional welding helmet must meet the shade requirements, which are measured in DIN. The DIN scale allows you to control the level of darkening of the filters, and based on these indicators the quality of the screen and the mask as a whole is judged.

As a rule, the light filter operates automatically in the range from 3 to 15 DIN, that is, with a darkening of 3-4 DIN, the welder works with the parts, preparing for welding, after the arc is ignited, the sensors are activated, and the protective glass is darkened to 13-15 DIN. The screen brightens to 6-7 DIN immediately after welding, when the parts being welded are still hot.

What else to pay attention to

In addition to the above, you must take into account:

Weight of the mask – a heavy welding helmet creates a load on the cervical vertebrae, especially if the volume of work is large;

Convenient fastenings of the welding helmet will allow you to work comfortably;

An air filter is necessary when working with stainless steel and some other metals that emit harmful substances when heated. As a rule, the filter works in tandem with a fan.

Prices for chameleon welding helmets

The range of prices for chameleon welding helmets is truly wide. Here are just a few models:

The 3M™ SPEEDGLAS™ 9100XX MP AIR welding helmet costs more than 200 thousand rubles and includes five protection elements: for the eyes, breathing, head, face and hearing. This is a professional welding helmet designed for long-term work in difficult conditions.

Welding helmet Svarog AS4001F with air supply device. A relatively inexpensive welding helmet that allows you to work safely in contaminated environments. In addition, high protection against ultraviolet and infrared radiation allows the welder to maintain health. The cost of a welding mask is in the range of 45-48 thousand rubles.

How to choose a welding mask - recommendations from experts

14.02.2018 11:43:48

In order for welding work to take place without harm to the cornea of ​​the eyes, you can use many different devices. The best way to preserve your own vision and not expose it to the harmful effects of bright flashes and ultraviolet radiation is to use special masks for welding.

These devices have been known since time immemorial, but modern models are several orders of magnitude superior to their predecessors, which were used 10-15 years ago.

  It is for this reason that in order to get a suitable model at your disposal and not overpay for unnecessary characteristics, you must approach the choice of a welding mask consciously.

The best manufacturers of welding masks - which company to choose

Currently, there are a huge number of welding helmet models on the market from a variety of manufacturers. When choosing such a tool, you should give preference to products from well-known, reputable manufacturers of construction equipment, as well as those companies that are specifically engaged in the production of professional welding equipment. In general, we can recommend products from the following manufacturers for purchase:

Understanding and choosing the best option is not difficult. All you need is to carefully study the characteristics of a particular model and determine whether it suits your operating conditions or not.

Operating principle and design of a welding helmet

A welding helmet is a special protective device designed to perform a number of protective functions:

1. Protecting the cornea from flashes of bright light and ultraviolet rays, which, with constant exposure, can lead to deterioration and even loss of vision;

2. Eye protection from scales formed during metal welding in the form of small slag particles;

3. Protection of the eyes and respiratory system from caustic and toxic gases released during the welding process;

4. Thanks to the fixation on the head, a correctly selected mask frees up the welder’s second hand, which makes the welding process much more convenient and handy;

The design of any, even the simplest, welding mask includes two main elements:

1. A special casing that covers the welder’s face, head and part of the neck while working;

2. A special viewing window with an installed light filter that protects against ultraviolet radiation, bright flashes and rebound scales. Its design is such that the welder has the opportunity to observe the process - he sees the seam itself, as well as the contours of the surfaces being welded;

3. Depending on the design of a particular model, the manufacturer can install many additional functions, the most significant of which are:

4. A control element that regulates the degree of darkening of the filter;

5. Anatomical fixing element for mounting on the head;

6. A special panel designed to charge the built-in batteries from the flash during welding;

Classic welding masks

Devices known since Soviet times. Despite the simple, and even primitive design, they cope with their basic functions quite well. The casing of such masks is made of plastic or pressed cardboard (the second option is lighter and better to use), and ordinary black glass, inserted into special grooves, is used as a light filter.

• Easy to operate;
• Possibility of replacing the filter with an analogue one with a higher or lower indicator;
• Good protection from major sources of danger;
• Low cost;

• Low durability - cardboard models swell when exposed to moisture;
• Insufficiently comfortable head clamp;
• Plastic models are heavy and rigid;

Chameleon masks

Advanced analogues of the above-described models, which use a special liquid crystal panel sensitive to the light source as a light filter. During welding, it becomes as dark as possible, protecting the welder’s eyes from flashes of bright light and exposure to ultraviolet radiation.

As soon as the process stops, the mask automatically brightens, and the welder can personally observe the results of the work done. The entire circuit is powered by an electrical element - a battery or an accumulator and allows you to adjust the brightness directly while making a weld.

For this purpose, a special regulator is used, which is convenient to adjust even with welding gloves.

• Convenient to use;
• Convenient head support that does not cause discomfort even during long-term use;
• Availability of warranty for many popular models;
• Possibility of automatic and manual brightness adjustment;
• Durable and practical housing;

• High cost of good models;
• Low efficiency of the LCD panel in sub-zero temperatures;

Masks equipped with forced ventilation

Professional models designed to work in particularly difficult, harmful or life-threatening conditions. We can say that these devices combine a chameleon mask and a classic respirator, which is fixed on a special waist belt.

It has a built-in compact electric motor that sucks in air, as well as a filter element that separates harmful particles.

These devices are highly specialized and not every welder needs them, but to work in hazardous conditions one cannot do without them;

• Easy to use, sealed;
• Excellent filter parameters and wide viewing angle of the viewing window;
• High quality air filtration;

• High price;
• Cumbersome design;
• The need to carefully monitor the condition of the filter, as well as the power source from which the electric motor operates;

Welding helmet selection options

Dimensions of the viewing window

Everything here is quite simple: the larger the viewing window, the better the overview and visibility of the objects the welder is working with. In addition to the classic models, which are 90 millimeters in length and 30-40 millimeters in height, you can find masks with a larger window size, up to 130x60, on sale.

Overall dimensions and weight of the mask

In this case, more does not mean better: a heavy mask causes a lot of inconvenience and does not contribute to fruitful work. If welding work is sporadic and irregular, this parameter can be neglected. If there is a constant need for this device, the less weight the better.

Type of filter and degree of darkness

Budget models of masks use special tinted glass as a light filter, the degree of darkness of which varies quite a lot. It is measured in numbers and varies from No. 1 to No. 5. The higher the number, the darker the specific glass. For example, filter No. 5 is used when working outdoors, while No. 1-2 are widely used for welding in dark rooms.

Things are somewhat different when it comes to chameleon masks. The LCD panel in such devices is adjusted using a special slider, and the degree of darkness is measured in DIN and can vary from 5 to 15 units. Here the situation is different - the higher the value, the less dark the panel has.

Choosing a welding helmet | Blog | DNS Club

: 2 years ago

Welding is a rather risky profession, but you can’t live without it; even in the 21st century, manual labor is invaluable and cannot always be automated. Working with welding is not the easiest, and if you add certain risks to this, then not everyone dares to weld on their own. The requirements for organizing a workplace are not casually regulated and are quite high.

The most vulnerable organs when working with welding are the organs of vision and breathing. Bright light, sparks, high temperatures, toxic fumes - this is what protection is needed at all stages of welding. Welding masks provide partial and sometimes complete protection. Your health will depend on how responsibly you approach the choice of protection.

Agree, it is better to spend money once on purchasing high-quality protection than to pay bills for treatment for many years.

This is important to know: the effect of welding on the organs of vision and breathing

Under no circumstances should you work with welding without a protective mask, even if the entire work takes seconds. Welders are frequent clients of ophthalmologists, not only because they neglected the main rule, but also because they selected masks with insufficient protection from the effects of electric arc radiation. Arc welding is considered the most dangerous type of electric welding; the glow is the most intense, therefore, the degree of darkness of the protective mask should be high.

Damage during welding work can be caused not only by the intensity of radiation; most often, the harmful effects on the organs of vision and breathing are complex. They can be divided into 4 groups:

- Thermal. Damage is caused by high temperatures when working with electric welding with metal; injuries from hot fumes, hot metal or sparks are possible. It is recommended to choose protective masks made from materials that are resistant to high temperatures, with optimal body thickness, with fastenings, and without a tight fit to the skin.

- Chemical. As you know, most of the organs of vision and breathing are covered by mucous tissues, which are most sensitive to fumes, smoke, and chemical changes in the composition of the air.

Of course, in this case, a lot depends on what material you have to work with. A welding helmet cannot provide complete protection against chemical burns, but if you know that you will be working with metals containing nickel, chromium, etc.

, then when choosing, give preference to masks with the ability to filter air, completely closed like a helmet.

- Light. Not only the welder, but also third-party observers can get a light burn by just looking at the light radiation. Such a burn occurs from the radiation of ultraviolet and infrared waves, i.e. precisely those that we cannot see. Even a regular shield will do to protect against light radiation, but it is much more important to choose the right filter.

- Mechanical. Damage caused by sparks, fragments, etc. coming into contact with the eyes, skin, etc. Not only do metal shavings fly at speed, they are also hot, so contact with the eye, skin or hair can be costly to your health. The best option is to choose a welding helmet that protects the entire head, not just the face.

Types of protective filters

Light filters are a specific material that can filter out invisible and visible light spectra that are most harmful to vision.

Several types of light filters are used in welding helmets:

— Tinted glass. Used in classic old-style welding helmets. Impurities of non-ferrous metals, such as copper or nickel, are added to glass to reduce light transmittance. A higher content of impurities in glass provides lower light transmittance, and vice versa.

Glass tinting is marked according to both Russian (C4 - C8) and European (9 - 13 DIN) classifications. Upon external inspection, it is difficult to find differences in glass, however, C8 (DIN 13) has the greatest light protection.

To check the quality of the glass, it is enough to look through them at the incandescent lamp; through C4 the filament of the lamp will be clearly visible, through C8 the filament is almost impossible to see. If the result does not differ during inspection, this indicates poor quality of the product.

— Polymer filters. Not so long ago, materials appeared on the market with parameters superior to glass. Polymers are strong and lightweight, have ductility and the same shading properties as glass. Often combined with other materials to achieve better protective qualities. Widely used in combination with safety and tinting glasses.

- Chameleon. The most suitable filter providing complete protection. The automatically darkening filter adapts to any type of welding and different powers. The liquid crystal screen works on the principle of polarization of liquid metals.

Between the polarizing films are liquid crystals; under the influence of voltage, the crystals are aligned in such a way as to block polarized light.

In addition, chameleon filters provide constant protection from ultraviolet and infrared spectra; even in a faulty state, protection is provided from the most harmful radiation.

Welding helmets with chameleon filters have gained popularity among users for their versatility and reliability. Such masks do not require recharging or third-party power; they are equipped with built-in lithium batteries and solar panels.

They are equipped with photosensitive sensors for better adaptability to changes in radiation; illumination of the arc zone is possible.

The filter in its initial state is transparent, which allows you to perform intermediate stages of work in the mask, or use it in other areas.

When choosing an automatic light filter, you should pay attention to the adjustment options. The sensitivity of the filter allows you to configure the filter to turn on/off depending on the brightness of the arc. A useful feature when working on sunny days, when the filter can turn on in response to the sun.

The opening delay time is another important adjustment, necessary to prevent premature opening at the end of welding, since after the arc is turned off, the metal is still burning.

Weight and dimensions of the welding helmet

A parameter that should not be overlooked is the weight of the welding helmet. Working with hot metal and welding is not easy, but if you add to this a heavy helmet with limited air access, then it all turns into torture. The mask should not be heavy; in addition, it is advisable to choose a model with the ability to adjust the headband, seat depth and angle of the mask. The presence of additional softening pads will also not be superfluous.

Let's sum it up

So, what should you first pay attention to when choosing a welding helmet:

— degree of protection from visible and invisible radiation;

— type of filter, quality of manufacture and attachment to the mask (no gaps between the filter and the mask, replaceable filters must fit tightly to the body);

— type of mask body design (closed helmet, visor, goggles);

— accessibility of adjustment elements, reliability of fastenings.

How to choose a Chameleon mask and how to check it when purchasing

Date added: 11/13/2017

A welder's mask is necessary for anyone who uses welding equipment. From this article you will learn: how to choose a “Chameleon” welding helmet and how to test it without welding before purchasing, what to look for when choosing and much other useful information.

Before purchasing a mask, you should carefully read its passport. Even a very simple mask with an automatic light filter (ASF) has a passport, which indicates its degree of darkness, recommendations for the type of welding (MIG, MAG, MMA, TIG) and the type of battery.

How to choose a welding mask? Read more about all the intricacies of choice further in our article.

What is a “Chameleon” welding mask and how is it different from a regular mask?

The welding helmet protects the worker from IR and UV radiation, high temperature, harmful smoke, gases, sparks and metal droplets during the entire welding process. Ordinary masks are inexpensive and practical, but less convenient to use. Unlike a regular mask, which always has the same degree of darkness, the Chameleon can automatically change it based on sensor signals.

It is important to know that an automatic light filter only dims the normal brightness of visible light. Ultraviolet and infrared radiation are blocked by special protective layers and film filters.

Advantages of the Chameleon mask compared to a conventional welding mask:

• The work efficiency of a welder wearing a mask with ASF increases significantly. The worker manages to do more work in the same amount of time. It more accurately controls the welding arc from the very beginning of its combustion and the relative position of the parts during the welding process.
• A worker with a Chameleon has both hands free during welding. There is no need to wear another mask if you need to perform metalwork work - cut an edge, fit sheets of metal more tightly, clean a seam.
• There is no need to change filters, as when working with a regular mask, when the current changes significantly, or when choosing a different welding mode.
• The Chameleon dims automatically - you don’t need to put on or take off the mask, everything is clearly visible in it.

After weighing all the factors, decide for yourself what is better for you - a regular mask or a “Chameleon”.

Chameleon mask device

The mask consists of a body, a block of light filters, batteries, dimming adjustment knobs and a headband.

part of the Chameleon mask is a block of light filters, which consists of several layers of polarizing crystals placed in a vacuum. Light filters can change their light transmittance depending on the level of voltage applied to them.

There are several sensors on the outside of the mask that measure the brightness of the light and instruct the filter to close.

General recommendations when choosing a Chameleon welding helmet

It is best, of course, to focus on the opinions of real people who use such masks. We recommend listening to the recommendations of real welders, not salespeople from stores. Welders work with masks every day and have a better understanding of what they are talking about. When choosing a Chameleon welder’s mask, their reviews about the comfort of long-term work, the ease of switching settings and the practicality of using the mask are especially valuable.

The presence and number of adjustments of the light filter greatly influences the price of the Chameleon welder’s mask. There are masks with smooth and step adjustments, without adjustments, with manual adjustments of sensitivity and delay of dimming after the arc has died out. The delay allows you not to strain your eyes from the glow of the molten metal of the weld pool immediately after the arc breaks. The degree of darkness is adjusted automatically within a given range, depending on the brightness of the arc.

Internal adjustments are less convenient; to change them you will have to interrupt the welding process. External ones (on the outside of the mask) are more convenient; they can be adjusted during welding, but the settings may be lost if the mask is dropped or if it is accidentally touched. This is important to know if you are trying to choose the right Chameleon welder mask for yourself.

How to choose a Chameleon welder mask for safety and autonomy

There are several types of power supply for the mask filter:

• From a battery (battery or accumulator). It would be better if it is removable and to replace it you do not have to disassemble or replace the entire internal filling of the mask.
• From solar panels . Used in more expensive models of masks.
• Mixed . Battery together with solar battery.

It would be good if the mask had a low battery indicator. Then you won’t have to, having done half the work, urgently look for and change the batteries in the mask.

When choosing a welding mask, it is important to know about the number of sensitivity sensors. The more there are, the better. One sensor may not work due to a layer of soot, contamination, poor location, or it may be blocked by some object or obstacle.

For entry-level masks, 1-2 sensors are usually sufficient, for example, START-TREND with ASF 300. On professional masks there are 3-4 of them, as in the START-ARGON mask.

The sensors are located in different corners of the filter block of the mask, at the maximum distance from each other.

A good mask ensures high injury safety for the worker. The aerodynamics of good mask models are designed so that the fresh air that the worker breathes enters the space under the mask from the area as far away from the working area as possible. This reduces the amount of harmful gases that the welder breathes.

How to choose the right Chameleon mask for welding work based on ease of use

Some masks have a number of features that significantly increase the welder’s comfort and influence the choice of a chameleon mask.

• Possibility of installing additional diopter lenses directly on the light filter, as in the START-MASTER mask with ASF 605. Experienced welders often need to work in glasses in order to clearly see the welding site. Diopter lenses in the mask allow the welder to work without glasses, and he is not distracted from the welding process.
• Comfortable ergonomic headband. This is the most important indicator when choosing a Chameleon welding mask. Adjustments to suit head size are required. Wide and soft pads. Possibility to change the planting depth and adjust the distance from the eyes to the viewing window. Relevant for workers wearing glasses.
• Adjusting the angle of the mask at which it begins to lower. Possibility of fixing the mask at different angles.
• Smooth lowering of the mask after nodding the head.

Chameleon welding helmets, how to choose based on reviews

Typically, the best reviews come from masks in the upper price range. Positive reviews are influenced by the following features:

• Mask weight and size . The smaller and lighter the mask, with the same functional parameters, the better.
• Viewing window size . The most common sizes are 91 mm x 39 mm and 96 mm x 39 mm. The maximum size of the viewing window is 100 mm x 60 mm for the START-ARGON model with ASF 705. A large viewing window is more convenient.
• Switch welding or machining . Its presence is assessed very positively in most reviews regarding the choice of a chameleon welding helmet. Before and after welding is completed, there is often a need to carry out mechanical processing of a seam or part. Cut out the fistula, sand down the defects of the lower layer, beat off the slag crust, grind off the influx. This switch disables the darkening of the mask from stray sparks during mechanical work. Most welders note in their reviews that such a switch is very convenient and saves time. Its presence has virtually no effect on the cost of the mask.
• Mask material . Our masks are made only from high-quality plastic. Bad plastic can burst from overheating in the sun or at low temperatures.

How to choose a Chameleon welding mask by price

Click to enlarge

Budget models of masks cost from 950 rubles. These are quite simple but reliable masks that are quite suitable for household use when welding with low and medium currents in the MMA mode. The adjustments are stepwise, powered by solar panels, the quality of the plastic is average.

When choosing a Chameleon welder mask at a price in the range of 1.5-2 thousand rubles, you can count on more serious models. Such masks are suitable for welding with consumable electrodes at high currents, MIG-MAG and Plasma modes. They already have a combined filter power supply system, the ability to install diopter lenses and smooth external adjustments. Typically, masks of this price are used in workshops, garages and small construction sites.

If the price of a chameleon welding helmet is more than 2000 rubles, then our recommendation is START-OPTIMA with ASF 615 or START-ARGON with ASF 705. The masks in the upper price segment have everything: they are suitable for working with any currents in all welding modes (in including TIG welding), smooth dimming and delay adjustments, excellent aerodynamics, large viewing window, 4 sensors and several dimming ranges, durable and lightweight plastic.

How to check a Chameleon welding helmet when purchasing

The peculiarity of the operation of light filter sensors is that they react only to sudden changes in high-intensity lighting. There are several ways to test a mask. First you need to turn on the filter, and then:

1. If you look at the sun in a mask, the filter will close once and open almost immediately, since there is a constant light flux from the sun. Try opening and covering the sensors from the sun several times. The filter must be closed every time.
2. Look at a regular incandescent lamp in the mask. The filter should close and not open all the time while the lamp is shining near the mask. In a household network there is alternating current, which changes its direction 50 times per second. This is invisible to the eye, but the sensors must react.
3. Another way to check a chameleon welder’s mask without welding is to strike a lighter in front of the mask several times. The filter must be closed after each use.
4. Use your smartphone's flash. The filter should close with minimal delay, this is normal. You may notice a small bit of flash early on before the filter closes. The welding arc does not light up immediately, a spark appears first, the sensors react to it, and when the arc lights up a little later, the filter is already closed. And the flash goes off immediately at maximum brightness.

If none of the methods for checking a Chameleon welder’s mask upon purchase worked, it’s worth checking and replacing the batteries. If the mask has solar panels, leave the mask in the sun to charge them.

Several important features of Chameleon masks for welding

• Chameleon masks have restrictions on working at low temperatures. Typically the operating limit is -5-10 °C. The response time of automatic dimming can increase significantly as the temperature drops. Some insurance in this case is the proximity to molten metal at a high temperature and the hot breath of the welder while working. In the vast majority of cases, this is enough for the mask to work properly even at such temperatures.
• It is best to store the mask with ASF in the switched off state, so as not to discharge the batteries. You should not place the mask with the light filter down, as scratches and abrasions on the glass can then limit visibility and make work uncomfortable.
• Some expensive mask models have a forced ventilation system to prevent fogging of the viewing window. This is especially useful if work is carried out in closed and poorly ventilated areas.
• Filter response time. The shorter the response time, the less tired the welder’s eyes are. Normal time is considered to be from 1/10000 of a second to 1/35000 of a second.
• Trigger sensitivity. The operation of the light filter is influenced by many factors: welding mode, welding currents, level of sun illumination, reflected light, influence of welding arcs of other welders.

This is all important to consider if you are thinking about how to choose a Chameleon welding helmet.

We recommend investing once in good equipment that will ensure high comfort for the welder.

How to choose a welding helmet “Chameleon” - Buildman

Simple and not very convenient glass filters have been replaced by new generation devices. The work is based on the principle of polarization of liquid crystals.

When exposed to voltage, they change orientation and block light rays. In expensive analogues, several layers are used to ensure maximum uniformity of darkening.

Another filter blocks ultraviolet and infrared radiation. Its action is constant.

Sensors that catch the arc and an electronic unit are built into the housing. All layers together form a block, which is protected on both sides by plastic filters. You can work with a grinder or hammer away scale without removing the mask. Plastic filters are consumables and require replacement over time.

The chameleon mask is currently one of the best means of protection when working with a welding machine.

The most important point is the response time. Professional models operate in one millisecond. However, the performance of this parameter decreases when working in cold weather. This is a disadvantage of the chameleon mask, since their limit is -10 degrees. Respectable manufacturers indicate in the product data sheet the response time based on the ambient temperature.

You need to store the chameleon mask in a heated room, otherwise its resource will quickly be exhausted.

Advice. The chameleon mask is designed in such a way that welding aerosols flow around the welder’s head as quickly as possible, and he does not ingest harmful gases.

Settings can be adjusted without interrupting the work process. The buttons are located inside the light filter or on top; they are convenient to adjust by touch.

Filter classification

The light filter is the main element of the mask. EN379 is a European standard regulating the parameters of light filters. Next comes the notation through the fraction 1/1/1/2. Let's take a look at what this marking means.

• The first number is the optical class. It indicates how clearly and geometrically correctly objects will be visible through the filter. One is the best indicator. The higher the class, the faster your eyes will tire.
• Light scattering essentially means transparency. An increase in this number indicates an increase in optical turbidity.
• Shade is indicated in DIN or SHADE and characterizes the uniformity of the filter darkening. Which corresponds to the old marking C 4 -7 (4 - 9 DIN).
• The angular dependence of the degree of darkness is within 15 degrees.

Please read the product datasheet before purchasing to ensure the quality of the product.

Secrets of choosing a mask

The mask is sold complete with or without filters. According to regulatory documentation, it must be made from materials that do not conduct current, are resistant to splashes and radiation into the space, that is, the welder’s face will be safe. Almost all modern masks meet these requirements.

Domestic manufacturers use plastic or fiber in production. Chameleons of European brands are distinguished by their exquisite design. Leather masks are produced for working in cramped conditions.

What parameters should you pay attention to besides the mask design itself? Professionals advise the following:

• evaluate the weight, dimensions and configuration of the mask;
• adjusting the headband strap;
• check whether it is possible to install dioptric lenses.

The straps allow you to adjust the mask to fit your head. The ability to adjust the distance of the filter from the eyes allows you to set the viewing angle required for comfortable work.

It is better to buy a mask from a trusted manufacturer

If you need to use diopter lenses, you should think about purchasing filters with an extended viewing window, then you won’t need to lift the mask every time to look at the welding seam, this can be done over the lens.

Advice. Buy only certified chameleon masks with a warranty period and beware of fakes.

Light filter – selection criteria

When choosing a filter for a regular mask, there is no particular hassle; they differ only in the degree of darkening of the glass for different types of welding work. With a filter for a chameleon mask, everything is not so simple.

1. Not every manufacturer conscientiously cares about the safety of your vision. Therefore, be sure to check for a certificate that will confirm the quality of the product.
2. Possibility of changing the power supply. The built-in ones cannot be replaced; after their resource expires, you will have to buy new protection.
3. The higher the filter response speed, the better. For home use, one hundred microseconds is enough, for a professional, half as much.
4. If there are a large number of sensors responsible for the arc, the risk of spontaneous opening of the filter during the welding process is reduced.
5. The settings for the degree of darkness, trigger sensitivity and return to the starting position on a good mask are smoothly adjustable. This is especially worth noting. Step adjustment is considered a relic of the past.
6. The mode of operation with an angle grinder and some additional features make the welding process comfortable.

Advice. If the filter is designed to work with argon-arc welding, then it will cope perfectly with both electrodes and semi-automatic welding.

What does the market offer?

The leading positions in the production of masks and filters for them are occupied by China and Taiwan. However, the quality of the products leaves much to be desired: the filters do not operate on time or open spontaneously, which can have a very adverse effect on the health of the welder. But I'm pleased with the low cost.

Chameleons from a domestic manufacturer are reliable; their drawback is the possible spontaneous opening when working with argon welding.

OTOS is a Korean manufacturer. Sometimes these same masks go on sale under the French brand GYSMATIC. The weak point of this manufacturer is the filter; it can delaminate or become covered with stains and microcracks.

Remember that in a high-quality mask you should not experience discomfort in your eyes

Chameleons from European brands are not cheap, but their quality is high. A filter from one manufacturer will not fit a mask from another.

Here is a list of brands that produce reliable and high-quality welding helmets and have international certificates:

• OPTREL;
• OTOS;
• SPEEDGLAS;
• TECHMEN.

Advice. If during welding work you feel discomfort: burning, tearing and rapid eye fatigue, immediately put this mask aside; it cannot be used. Symptoms indicate poor quality filters.

Now you know all the intricacies of choosing a chameleon mask. Not only your health, but also the quality of your work depends on the correct choice of mask.

How to choose the right chameleon welding helmet, features of different products

A welder who is exposed to harmful ultraviolet rays from the welding arc must take care of his health, and even more so of his vision. Standard shields are not capable of providing the level of protection that a chameleon helmet has.

A mistake when choosing a chameleon welding mask can lead not only to facial burns, but also to loss of vision.

Just because the filter is darkened does not mean you are no longer exposed to harmful rays. Therefore, the question of how to choose the right chameleon welding helmet can be answered by reviews from welders who have been using this type of protection for a long time. How to choose a chameleon welder mask for comfortable work?

Unlike a standard shield, the Welding Chameleon takes welder protection to a new level. The principle of operation of such a mask is the polarization of liquid crystals . During provocation, they change direction and interfere with the effects of ultraviolet radiation. Masks in the expensive price segment use multi-layer protection, this ensures the most uniform darkening. And an additional filter provides blocking of infrared radiation.

The helmet has built-in sensors that detect the arc and provide constant eye protection. The entire structure is enclosed in a block, which is protected on both sides with the help of plastic light filters.

You can carry out related work (with a grinder, a hammer) without removing the protective helmet from your head. Plastic filters require replacement over time, as they are consumables. The key point of the protective process is the speed at which the light filter operates.

The response time of professional models is 1 millisecond.

The protective properties of a chameleon directly depend on the ambient temperature. If the temperature is below minus 10 degrees, the operation of the filter slows down. Conscientious manufacturers indicate the maximum operating temperature in the product data sheet. Adjustments can be made during the workflow. The buttons are conveniently located and easy to operate with tactile contact.

It is important to know ! The mask must be stored in a heated room, otherwise its service life will be reduced.

Criteria for choosing a chameleon mask

1. There are manufacturers who are not concerned about the safety of your vision. It is necessary to require a certificate that confirms the quality of the product.
2. Look for a sample with a replaceable power supply. Built-in batteries cannot be replaced. After the resource expires, you will have to buy a new chameleon helmet.
3. The quality of the mask determines the speed at which the filter operates.

   For short-term use, 100 microseconds is enough, but for a professional, the response time should be half that.

4. The mask is equipped with a large number of arc detection sensors, which eliminates spontaneous operation of the filter during the welding process.
5. The response speed of the protection and the return of the light filter to its original state occurs smoothly in a high-quality helmet.

   Stepping steps are a relic.

6. If, with the protection lowered, it is possible to work with an angle grinder or perform other related tasks, but at the same time be protected from ultraviolet radiation, then such a product is of high quality.

Pro tip : The light filter is designed to work with argon-arc welding; it can protect both from electric arc welding and from working with semi-automatic machines.

Popular models offered by the market

The leading countries in the production of masks and filters are Taiwan and China. But sometimes the quality of their products leaves much to be desired: the filters do not work correctly, which negatively affects the welder’s vision. The domestic manufacturer provides products of sufficient quality, but sometimes the filter does not work correctly when working with argon-arc welding.

The Korean brand OTOS, sometimes sold under the French brand GYSMATIC, has a weak point - the filter. There were cases of delamination, as well as the appearance of stains and microcracks.

The masks that Europe offers are higher in price, but their quality is consistently high. A filter of one sample may not fit another product. Next, there are several brands that produce high-quality masks that have the appropriate quality certificate:

• TECHMEN.
• OPTREL.
• OTOS.
• SPEEDGLAS.

Professional advice . If during welding work discomfort occurs in the form of burning, fatigue and tearing of the eyes, you should stop using such a mask. Most likely the product is of low quality.

Now you know all the secrets of the chameleon shield. Not only the health of the welder’s eyes, but also the quality of the current work depends on high-quality protection.

How to choose the right chameleon welding helmet, features of different products - Machine

When performing welding work, a person is constantly in danger due to some features that accompany this type of work: bright, blinding light from the welding arc, infrared and ultraviolet radiation, hot metal, toxin impurities. That is why it is very important to strictly follow safety regulations. Special protective equipment should be an integral part of any type of welding, so today the relevant question is: how to choose a chameleon welding mask. This will be discussed in this article.

What are welding helmets?

A welding mask is a mandatory element necessary for the work of a welder, since it protects the worker from the negative effects of the electric arc on the eyes.

With this device, the person performing welding work can examine in more detail all the shortcomings in the formation of the cooking pool and ultimately obtain the most reliable and high-quality seam.

The design of such products is quite simple.

The structure of the chameleon welding helmet is as follows:

• body (head cap) made of fiber or plastic,
• a light filter, which can either be included with the mask or be a separate element,
• steam vent, designed to protect glass from fogging,
• adjustable fasteners, through which you can adjust the mask to the desired size,
• consumable elements (polycarbonate filters), which must be changed periodically.

When choosing a welding helmet and deciding which welding mask is suitable in a particular case, it is very important to pay attention to the material of manufacture. It must have heat resistance and electrical insulation.

Types of welding helmets

Are you choosing a mask and don’t know which mask is the best? Then you need to familiarize yourself with the modifications. Absolutely all welding helmets, including the chameleon, are divided into several varieties based on optical parameters:

• Optical class. This indicator indicates the quality of the filter glass and the entire assembly. The higher this indicator, the higher quality the image and the less distorted the picture.
•  Light scattering. In other words, the transparency of the glass. Look at the marking, the higher this indicator, the more light it will transmit.
• Angular degree of darkness. Based on the angle of the light filter to the area where the work is being done, the glasses of the mask change and darken.

All four described parameters can be found in the markings located in the filter. Designations are presented in the form n/n/n/n. Each value has an indicator from 1 to 3. Moreover, the lower the number, the higher the indicator of each item.

In addition, chameleon masks have such indicators as: speed of activation of protection and enlightenment, sensitivity of sensors.

The first parameter is significant for masks, since light travels very quickly, which means the filter must darken in thousandths of a second. And in order for the work to be as convenient as possible, the optics must also be cleared quickly.

The key parameter is the degree of darkness, since it is this that protects vision from bright glare.

How to choose the right chameleon welding helmet?

Perhaps everyone wants to have the best chameleon mask. The most important point in making the right choice of mask and finding a suitable model is determining the work for which it will be used.

These can be either the most ordinary models without bells and whistles, or slightly improved with auxiliary options. Make sure that the mask has internal fixation and darkening control, they will make the work much easier.

 In turn, convenience during the welding process will help increase the quality of the seam. Separately, it is worth mentioning the indicators of filter switching.

More popular are modifications in which the mode switching time is minimal, since this simplifies the process of activity and does not have such a negative effect on vision, because the eyes have much less contact with the arc flash.

Today there is a wide variety of chameleon welding helmets on the market. If you are at a loss about the question: how to choose a mask for welding semi-automatically or in another way, then you should take a closer look at such parameters as:

• Manufacturer. It is very important to find out at which factory the filter is produced, because... Its certification and optical class of the product depend on this. This also determines the warranty for the life of the product. That is why, if the mask does not have any information according to the criteria described above, then it is worth considering, because its quality is in question.
• The next point that you need to pay special attention to is what type of welding the filter is intended for. Because if you do not have information on how to choose a chameleon for inverter/electric arc welding, then you need to find out the scope of application of the filter. Argon-arc are recognized as absolutely universal and have found active use in all types of welding work.
• View area size. The width of the glass determines the visibility during welding. The larger it is, the better the welder will see the parts. However, there is one obvious drawback here, since such filters are very fragile, you need to be extremely careful with them.
• Weight, design features of the headrest and other external parameters that affect ease of use.

The mask should not weigh too much, and also make sure that it does not fit too tightly to your face, otherwise it will be difficult for you to move.

• The number of types and types of adjustments on the mask. Professional welding masks have eclipse adjustment limits from 9 to 13 DIN. It is also recommended to choose devices so that you can adjust the sensitivity yourself as needed. This way you can set protection against light radiation, which is directly affected by the temperature regime of the electrode or the metal of the workpiece. This also includes the delay time for clearing after welding is completed. There are two types of adjustments. The outer one is located on the left side of the mask, and the inner one is located on the filter itself. Such filters differ in the smoothness of switching. There are smooth ones, which adjust the eclipse gradually, and stepped ones, in which the degree of darkening changes jerkily.
•  The last indicator is price. Experts advise giving preference to high-quality masks. Yes, they will cost more, but they will serve you well for a long time.

Having studied all the indicators described above, you will understand how to choose a chameleon welding helmet correctly, and it will also be much easier for you to understand which welding mask is suitable specifically for your case.
