Chameleon welding helmet does not darken: reasons, what to do, is it possible to fix it yourself
Welding work is a high-risk task, so a person must provide himself with reliable protection so as not to get hurt during work.
Very often a person suffers from sparks when working with metal, different types of radiation, gases and vapors are released during welding, different types of radiation
The Chameleon welding mask is your first assistant in protecting against unpleasant consequences during work.
Features when working with a chameleon welding helmet
There are usually two types of masks on sale: masks with a fixed degree of darkness and masks, also called chameleon.
Chameleons are more expensive, but they are also distinguished by their quality: they have an automatic light filter that instantly reacts to intense light, thereby protecting their eyesight.
Depending on the brightness of the light radiation, the Chameleon mask instantly darkens, which will protect the owner of the mask from eye damage.
The structure of the darkening filter is layered - the manufacturer has distributed it so that liquid crystals alternate with a special film.
The principle of operation of the mask can be described as follows: the crystals become in such an order that some of the light simply does not pass through.
How to fix it yourself
The main question is what is the problem with dimming. Let's see what goes wrong most often. A common defect is that a chameleon mask does not darken light radiation, and this is its main task.
One of the root causes may be batteries that have zero charge.
The mask has two batteries: standard AA batteries and solar energy, which is powered through a panel in the body. Usually just replacing the battery is enough.
But if replacing the batteries does not help, then you can try charging from solar energy, leaving the mask for a short period in the sun or bright light.
But this is not the main reason and the way to solve it. This is not one of the possible sources of the dimming problem. There may also be a problem with the protective glass. Usually this damage is visible to the naked eye: chips, cracks, abrasions.
The solution to this problem is usually to replace the mesomorphic glass, which is one of the most expensive elements of the mask. But only glass that is completely similar to the previous one will do, watch this carefully.
“If the light filter blinks, check whether the protective glass is dirty. In the worst case, it may be damaged. If it is damaged, the light filter with protective glass must be replaced.”
With such a problem, it is better to contact a specialist rather than deal with it yourself. The service center is here to help you. Of course, this is not the most economical option, but this way you will know that the root cause of the defect has been accurately identified and they know how to eliminate it.
When working with a welding machine, many factors affect vision impairment, which the Chamaleon mask helps prevent, therefore, when using the mask, make sure that the headband is properly secured, make sure there is good lighting, check that there is no protective film on the glass, and monitor the level of darkness.
High and low temperatures often affect the degree of darkening and may be the reason for its delay. The manufacturer warns that at -10C the Chameleon mask may not work correctly.
How to use a welding mask
Be sure to read the user manual before use, which can make it easier for you to adjust the mask for welding tasks and avoid any obscuring problems.
But remember:
- the Chameleon mask should fit tightly to your head and not create voids - this will give you confidence when working that the mask will not fall off and you will not be injured;
- To replace the power supply elements, it is necessary to transfer the shield to grinding. If the red light comes on, you need to change the batteries;
- if you are prone to allergies, then make sure that the belt for putting on does not rub the areas of contact, otherwise it is more likely that you may experience skin irritation;
- Do not use detergents or aggressive cleaning agents to clean the damper;
- the light filter does not handle moisture and may fail;
- if you notice that the quality of the darkening has deteriorated or is absent, then stop welding until the cause of the malfunction is determined;
- It is better not to change the specified settings for the light filter. Only the spare parts specified in the instructions are suitable for its adjustment;
- do not use physical force on the shield;
- It’s logical to take the filter cartridge to a specialist to find out what’s broken in it;
- a surface with elevated temperatures can damage the shield and cause dimming problems;
- The Chameleon mask is not used for plasma or gas welding.
How to serve
Regular maintenance will help protect the device from any breakdowns and dimming problems in particular. It is reasonable to carry out repairs no more than once a month. You can provide superficial care yourself: to do this, just wipe with a cotton cloth soaked in water.
Oily substances and abrasive materials are not suitable for cleaning the shield and may damage it. Cleaning should occur without much use of physical force.
- How to adjust a welding helmet
There are two types of adjustment. It is important to configure all the characteristics before work, which will increase the efficiency of use. Let's look at what types of adjustments the Chameleon mask has.
The shield should fit snugly to the head. There is a handle on the back of the head with which you can adjust the desired diameter. All these manipulations should be carried out with a shield on your head in order to more accurately feel the tension.
There is also a strap on the top of the head that can adjust the height of the Chameleon mask: higher or vice versa - lower. Be sure to check the fit of the shield before starting cooking.

Adjust the fit until you are sure the shield is securely attached to your head.
- What distance should be adjusted from the eyes to the filter?
During operation, it is possible to change the fixation of the Chameleon mask: move it away and bring it closer to the face by loosening the locking nuts. Make sure that the distance from the eyes does not differ. If the result suits you, tighten the fasteners.
- Adjusting the Darkness Level
Depending on what type of welding and what current strength is used, there is an option to choose how much to darken the mask. Even during the welding process, the level of darkness on the outside of the damper can be adjusted.
Sensitivity can be divided into high and low. It is possible to set the average sensitivity. But when TIG welding you need to use high sensitivity.
This is the most optimal setting and it is better if it is always set, and during the welding process it is adjusted and lowered until the cure is perceived only from the welding arc, despite the light source.
This is regulated according to a scheme characteristic of a certain type of welding, which is characterized by a certain level of sensitivity.
There is a knob on the inside of the cartridge that makes adjustments. For spot welding, a short delay is suitable, and for a long delay, welding with a high amperage is suitable. Proper adjustment will eliminate dimming problems.
Conclusion
Auto-dimming controls exposure to harmful radiation. There is a large selection of shields in this direction: Forte MC-1000, Centaur SM-152, Vitals Professional Thor 2500 LCD
Don’t forget to check the shield when purchasing so as not to purchase a faulty or defective one. Only in case of minor damage and dimming problems can you carry out repairs yourself.
Such breakdowns include replacing power supplies or protective glass. If the filter breaks down, you should contact a service center, where they will replace it efficiently and quickly.

How to adjust a chameleon welder's mask
Chameleon type welding helmets are so named because the light filter automatically changes the degree of darkness depending on the intensity of the light flux. This is much more convenient than a regular shield or an old type mask with a replaceable filter. Having put on the chameleon, you can clearly see everything even before you start welding: the filter is almost transparent and does not interfere with your work.
When the arc is ignited, it darkens in a matter of seconds, protecting your eyes from burns. After the arc goes out, it becomes transparent again. You can carry out all the necessary manipulations without removing the mask, which is much more convenient than raising and lowering the protective shield and much better than holding the shield in your hand.
But a wide selection of different priced items can be confusing: what is the difference, and which one is better? We'll tell you how to choose a chameleon mask below.
Chameleon welding masks come in a wide variety. Choosing is not an easy task at all. Moreover, it is not so much the appearance that is important, but the quality indicators
Light filter in a chameleon: what is it and which is better
That small glass that is installed on the welding helmet is a real miracle of science and technology. It contains the latest achievements in optics, microelectronics, liquid crystals and solar energy. This is the “glass”. In fact, this is a whole multi-layered cake, which consists of the following elements:
- liquid crystal cells (several layers - the more, the better);
Approximate composition of an automatic light filter in a chameleon welding mask (To increase the size of the picture, right-click on it)
The main and main advantage of a chameleon welding mask is that even if it did not have time to work, it will not let in ultraviolet and infrared radiation (if the mask was lowered). And the degree of protection from these harmful effects does not depend in any way on the settings. In any case and with any settings, you are protected from these types of harmful influences.
But this is only if the “pie” contains the appropriate filters and they are of the proper quality. Since it is impossible to check this without special devices, you have to rely on certificates. And masks must have them.
Moreover, on the territory of Russia only two centers can issue them: VNIIS and the Federal State Budgetary Institution at the All-Russian Research Institute of Labor Protection and Economics.
To be sure that the certificate is genuine, its number can be found on the official website of the Federal Service for Accreditation at this link.
This is a form on the Rossaccreditation website for checking the certificate. You can fill in only the number, leaving all other fields empty (To increase the size of the picture, right-click on it)
The certificate number is entered in the appropriate field and you receive the validity date, information about the applicant, and the manufacturer. A small note: the abbreviation RPE stands for “optical personal protective equipment.” This is what a welder's mask is called in bureaucratic language.
If such a certificate exists, the following message will appear. By clicking on the link you will see the text of the certificate (To enlarge the image size, right-click on it)
The most important thing is that you make sure that this product (by the way, compare both the name and model) is safe for your health.
Classification of automatic welding filters
Since the light filter and its quality are the key element in this product, you should start choosing a chameleon mask with it. All its indicators are classified according to the EN379 standard and must be displayed on its surface through a fraction.
One of the filters in the chameleon mask. Its classification is indicated in red
Now let’s take a closer look at what is hidden behind these numbers and what they should be. Each position can contain a number from 1, 2, 3. Accordingly, “1” is the best option - first class, “3” is the worst - third class. Now let’s talk about which position displays which characteristic and what it means.
Explanation of EN37 classification
Optical class
It reflects how clearly and without distortion the picture will be visible to you through the filter. Depends on the quality of the protective glass (film) used and the build quality. If "1" comes first, distortion will be minimal. If the values are higher, you will see everything as if through a crooked glass.

Operating principle of the chameleon welding helmet
On the market you can find two types of shields, with a fixed degree of darkness and chameleon masks. Masks of the second type are distinguished by their higher cost and the presence of an automatic light filter that can respond to the intensity of light radiation, thereby protecting vision.
The principle of operation of the chameleon welding mask is based on the fact that the light filter instantly reacts to light radiation and, depending on the intensity of the latter, automatically darkens the light radiation. The auto-darkening filter, in turn, has a layered structure in which layers of liquid crystals alternate with special films.
At the moment the arc is ignited, the crystals are arranged in a certain order and do not allow part of the light to pass through.

Based on this principle, you can effectively protect your eyesight from the influence of bright vision.
Existing faults. Do-it-yourself chameleon welding helmet repair
Let's look at the question of why the shield may not work. Let's look at typical welding helmet malfunctions. It often happens that a chameleon welding mask does not perform its main function, namely, it does not reduce the level of light radiation. The essence of the problem may lie in dead batteries.
The chameleon welding helmet can be powered by both regular AAA batteries and a solar panel located on the body. Simply put, replacing the battery can solve the problem. If we consider the first method of powering the shield with energy, then simply insert the batteries into it.
If powered by a battery, you need to hold the shield under a bright light to charge it.
But even after this procedure, you may find that the shield still does not work. The reason may be the protective glass. Typically, with this type of malfunction, cracks, chips and other mechanical damage are visible on the glass. In this case, it is necessary to replace the liquid crystal glass, which is the most expensive component in the mask. It is important to remember that the new glass must fully comply with the previous one in all respects.
The filter may blink. Here the protective glass may be either simply dirty or damaged. In this case, it is better to immediately change the filter with protective glass.
It is better not to repair the light filter of a welding helmet yourself. It would be better to contact specialists at a service center. This will cost money, but the service center can accurately identify the cause of the breakdown and specialists will easily fix it.
Poor visibility does not have a beneficial effect on vision, so it is important to properly secure the headband, install a good lighting source in the workplace, remove the film from the protective glass, and adjust the degree of darkness. At low temperatures, there may be a delay in dimming. Do not use the mask at temperatures below - 10 degrees Celsius.
How to properly set up a chameleon mask for welding? What do you need to remember when working?
In order to know how to set up the mask and how to check its performance, it is better to refer to the operating instructions. Important to remember:
- the chameleon mask is not suitable for plasma and gas welding and cutting;
- Do not leave the shield on a hot surface;
- It is better not to disassemble the filter cartridge;
- the shield will not withstand strong impacts;
- Changes cannot be made to the filter. It is allowed to use spare parts specified in the instructions;
- if the chameleon welding helmet does not darken the image, you need to stop working and identify the possible cause of the malfunction;
- it is necessary to prevent moisture from entering the light filter;
- When cleaning the shield, it is not recommended to use detergents and solvents;
- the headband for putting on can cause an allergic reaction, the straps must be adjusted correctly to prevent skin irritation;
- In order to change the batteries, switch the shield to grinding mode. When the red light on the filter lights up, you need to replace the batteries;
- Before starting work, you need to adjust the mask to suit yourself to achieve maximum comfort. You can select the darkness level, delay time and sensitivity level.
Carrying out maintenance
In order to reduce the likelihood of breakdown to zero, it is necessary to carry out maintenance from time to time. The minimum interval between repairs should be one month.
To remove dirt and dust, you can use a cotton cloth pre-moistened with a non-aggressive liquid. Do not use oil-containing cleaning agents or abrasive materials as this may damage the protective shield.
All cleaning actions must be carried out carefully; do not put too much pressure on the material.
Types of adjustments for chameleon welding helmets
There are several types of adjustments in a welding helmet. Before starting work, it is extremely important to configure all the characteristics. This is necessary for the most effective use of the mask when working. The following are the types of adjustments.
Preparation under the head
It is extremely important to securely fix the shield on your head. The diameter of the headband can be adjusted using a handle located on the back of the head.
The procedure must be carried out with a shield on the head, which will allow you to obtain the necessary tension. If the headband sits high or low, it should be adjusted using a belt passing through the top of the head.
Before starting work, check the fit of the shield. If it does not sit securely, you need to readjust it.
Adjusting the distance from the eyes to the filter
The mask can be moved away from the eyes and brought closer to the eyes by loosening the locking nuts. The distance from both eyes and the filter should be equal. If everything is done correctly, the locking nuts should be tightened.
Adjusting the darkness level
Depending on the type of welding and the current value, you can select the required degree of darkening from the table. This can also be done during operation using the regulator, which is located on the outside of the shield.
Adjusting sensitivity
There are two types of sensitivity: high and low. For most cases, you can set the control knob to the middle position. When working in TIG mode at low current values, maximum sensitivity is required.
For optimal settings, it is better to set the sensitivity to maximum, and then reduce it until the filter begins to perceive light radiation only from the welding arc, and not from external light sources (the sun, lighting lamps, etc.).
The required degree of sensitivity can also be selected according to a scheme where each type of welding has its own level of sensitivity.

How to set up a Chameleon mask for welding
01.08.2018
Like all other welding helmets, the Chameleon protects the welder's eyes from infrared radiation. The automatically adjustable light filter operates in a convenient mode: the screen changes the degree of darkness depending on the illumination of the working field. When the Chameleon welding helmet does not darken, it is dangerous to work.
You need to figure out why the screen is not working. Sometimes it is enough to change the power supply elements and charge the battery. A dirty screen reacts worse to light; it may need to be wiped. If this does not help, it is better to turn to professionals.
Adjusting the Chameleon welding helmet
To understand how the Chameleon welding helmet works, you need to know the basic structural elements of the protective device. The overview screen has a layered structure:
- fireproof glass that does not transmit ultraviolet and infrared radiation;
- layers of polymer crystals that change transmission capacity;
- In order for the filters to darken, they are connected to a current source;
- light sensors (from 2 to 4, depending on the model);
- connection diagram to the power supply.
At the moment of welding, a spark appears, then a luminous flux. The radiation triggers the sensors, the crystals are polarized, and the screen darkens. The welder sees the junction of metals within the range acceptable to the eye. After turning off the light source (electrode or arc), the sensors are triggered again. The screen brightens.
The tuning system regulates:
- the degree of screen darkening, it is selected according to the instructions, depending on the type of welding;
- sensitivity to changes in light flux;
- shutter speed, that is, the time period for turning off the light protection.
The adjustment is made at the preparatory stage, when the serviceability of the Chameleon mask is checked before work.
How to properly prepare a welding helmet for work is written in the operating instructions. Setting up a chameleon mask includes several steps:
- a convenient distance from the face to the protective screen is set, this is done by loosening the clamps;
- The position of the filter is adjusted, the comfort of viewing the working area depends on this;
- the intensity regulator is installed: it is determined in what mode the Chameleon welding mask is used, the operating instructions must contain adjustment tables;
- depending on the current strength of the welding machine and the illumination of the workplace, the sensitivity mode is selected; high is indicated by the letter “H”, low – “L”, minimum – “L0”, it is selected experimentally, it is easy to adjust the Chameleon welder masks during work;
- the holding time depends on the type of welding; for spot welding, a minimum interval is enough; for electrode welding, when a melt pool is formed, it is necessary for the screen to remain darkened longer.
Possible malfunctions and methods for eliminating them
- The screen will not respond to light unless connected to a power supply. If the model is equipped with AAA alkaloid batteries or rechargeable batteries, charging indicators are displayed in the screen area. If the red light is on, it's time to replace the batteries. Solar panels are charged while welding. If the mask does not turn on, point it towards a light source for a few minutes.
- If the screen darkens unevenly, check the distance from it to both eyes. Perhaps while they were adjusting the mask and adjusting it to the head, the filter shifted. It should be parallel to the face. Loosen the clamps and align the casing.
- If the screen flickers during welding, it may be due to the outer glass. Sometimes it is enough to wash it.
In case of mechanical damage (scratches, surface chips) it must be replaced. If the filter continues to act up, check the cleanliness of the sensor surface. When there are two operating modes (welding and grinding), check which position the switch is in. The screen may flicker when low-current welding in low sensitivity mode.
The desired level can be established experimentally during operation.
- The filter does not darken immediately in the cold. Viewing screens quickly change the degree of darkness in the temperature range from +50 to -10°C; Chameleons are not intended for harsh winters.
- If the weld seam is difficult to see, there may be several reasons. Sometimes the film is forgotten on the protective glass.
You can try cleaning it, switching the dimming control.
How to test a Chameleon mask without welding
When you hold down the Test button for five seconds, the filter should darken. If there is no such configuration function, you need to check Chameleon in other ways. The sensors are triggered by a powerful light beam. The filter is turned towards the light source at least three times, the screen should darken in all cases. Light protection reacts to:
Checking the Chameleon filter
- radiation from the sun (the filter should darken and open after an exposure interval, because the flow is of constant intensity);
- red spirals of incandescent lamps (darkening persists throughout the entire period of being near the emitter; it operates at an alternating current frequency);
- a spark from a silicon lighter (the filter darkens sporadically when the wheel knocks out a spark);
- remote control for household appliances (sensors react to infrared radiation pulses, the light output of the remote control is uniform);
- smartphone screen during flash.
If the filter does not respond, check the power supply: change the batteries or batteries, charge the solar panels. The sensitivity of the filter is checked with an incandescent lamp. If the spiral is equally visible at different settings, the regulator does not work.
How to set up a chameleon mask for welding? — Metals, equipment, instructions
Welding, regardless of the specific type and method, is a rather dangerous process. The organs of vision are most at risk. Therefore, welding helmets with highly tinted glass have been created that can provide complete eye protection.
However, using conventional masks comes with one difficulty: the problem of igniting the welding machine. The fact is that until the welding arc is ignited, practically nothing can be seen through the mask.
You have to start the welding machine blindly; one careless movement, especially when working with thin metal, can completely render the workpiece unusable. If you do not use a mask, then bright light will negatively affect eye health.
To solve this problem, chameleon welding masks were created. It got its name from the presence of special light filters in its structure. In normal condition, when the welding machine is turned off, the degree of darkness is 4 DIN, this value is sufficient to ensure normal inspection. As soon as the welding arc starts, the degree of darkness instantly increases to levels from 9 to 13 DIN.
A chameleon-type welding helmet allows you to solve two problems at once: eye protection and ease of operation when the welding machine is turned off. It is for this unique ability that masks of this type have gained their popularity among both amateurs and professionals. But a “chameleon” mask is much more difficult to choose than a classic one.
There are many manufacturers that produce chameleon masks for welding. In addition to differences in technical characteristics, they may differ in purpose, for example, for classical gas welding, for semi-automatic welding, in an environment of protective inert gases, etc. In order to choose the right mask for the required type of work, you need to know their differences.
It is also worth noting that the production of chameleon-type welding masks is strictly regulated by state standards.
Classification
The state standard, in accordance with which masks are produced, obliges all manufacturers to apply markings to the outer surface of the product. Since the main difference between a “chameleon” and a regular classic mask is the ability to automatically adjust the darkening, the classification occurs according to the technical parameters associated with this property.
The marking consists of four digits separated by a fractional symbol. Each number represents a specific characteristic. It can take values in the range from one to three, where one indicates the highest level of quality, three the lowest. In addition, you also need to know the designation of each number.
1. The first digit indicates the optics class of the product. It determines the quality of vision through the glass of a mask with a light filter. The main components that influence changes in this parameter are the quality of the original glass, the light filter and the film used.
2. The second number tells us the degree of light scattering. This parameter indicates the degree of haze of the image obtained through the glass of the mask. The quality of this characteristic is determined by the purity of the liquid crystals used.
3. The third number determines the uniformity of the degree of darkness. The fact is that the glass in chameleon-type welding helmets is darkened unevenly. The parameter value indicates how much the darkest zone can differ from the lightest.
4. The last digit shows the value of the angular dependence. Its value tells us how dependent the light filter is on the angle of flashes entering the field of view of the mask.
Operating principle of chameleon type welding helmets
The welding helmet is very similar to other products of a similar role when considered in terms of design. "Chameleon" consists of several main components:
- body - is the basis for the entire structure, as a rule, it is made of fire-resistant durable material, which protects the head from metal splashes and the effects of high temperatures;
- light filter - this component is responsible for automatically adjusting the dimming level (some models also support manual adjustment);
- motherboard - without this component, automatic adjustment is impossible; it is a small chip that runs on battery power;
- power source - thanks to it, the system board operates; a lithium-ion battery is used to power it; if the welding helmet is equipped with two power sources, then most often the second is a solar battery.
In the normal state, without exposure to light from the welding machine, the glass of the mask is slightly darkened. It is covered with a layer of darkening film and several layers of liquid crystals. They are the ones who create the light filter.
In a quiet state, the light filter does not work, but as soon as a flash from the welding machine enters its field of view, the signal is instantly sent to the system board, as a result of which the glass is automatically darkened. The entire process described takes a fraction of a second. After the welding machine turns off, the glass does not brighten immediately.
Different models perform this process with different times, in any case it does not exceed five seconds. This property allows you to increase the level of security in case of emergency situations. On most popular models, this parameter can also be adjusted.
Approximate technical characteristics of chameleon-type welding helmets
Chameleon masks for welding have the following technical characteristics. The specific value of a particular parameter may change depending on the specific mask model. The general meanings are:
- glass dimensions have a universal standard: 110x90x9 (length, width and thickness), however, there are specialized models in which this parameter can take other values;
- The darkening level in standard mode for almost all models is 4 DIN;
- the degree of darkness in operating mode can take values in the range from 9 to 13 DIN;
- the response speed of the light filter can be from several ten-thousandths to three hundredths of a second;
- adjustment of the degree of darkening can be carried out both jerkily and smoothly;
- Almost every model has two sensors at its disposal;
- lithium-ion batteries and solar panels are used as power sources;
- the body is made of durable material that is resistant to high temperatures and open flames;
- The weight of the product is approximately half a kilogram.
How to use a chameleon welding helmet
Before using the product for its intended purpose, you must read the instructions for use, which are always present in the original packaging. Before starting welding work, you need to perform the following manipulations.
1. Conduct a full technical inspection for defects, breakdowns or defects. If the mask is to be used for the first time after purchase, you need to remove the protective films from the entire surface.
It is also necessary to remove the protective film under the plate; to do this, you need to dismantle it, remove the protection, and install it back.
Important: when checking, you should always pay attention to the technical condition of the cable that connects the light filter to the system board and control unit.
2. After inspection, if there are no defects, you can begin setting up the “chameleon”. It is performed in the following order:
- adjust the process of opening and closing the mask using special clamps;
- Next you need to adjust the working angle;
- You can also configure individual parameters, which include: the distance from the glass to the organs of vision, adjust the technical parameters of the product (if required);
3. After all checks and settings have been completed, you need to adjust the dimming level. To do this, you need to use a special control unit.
How to charge batteries in masks of this type?
The method for charging the battery depends on its type. If the mask uses a regular lithium-ion power source, then it can be charged using a regular household outlet of two hundred and twenty volts. Almost always, a charging adapter is included with the product.
If solar batteries are used as a power source, then the “chameleon” needs to be charged in the sun, or in bright, targeted light. If the mask is equipped with two types of batteries at once, then the charging process can be combined.
What to look for when purchasing?
The most important parameter to pay attention to when purchasing a chameleon welding helmet is the auto-darkening speed. The higher it is, the safer the welder’s visual organs are. It is best to purchase a model in which the light filter is adjusted smoothly, as this has less impact on the eyes and provides additional comfort during use.
The second thing you should pay attention to is the number of batteries. It is best if the welding helmet has two different power sources. This will protect against unexpected battery drain.
Important: despite a fairly large number of important parameters, first of all, when purchasing, you need to be guided by the comfort of using a welding helmet.
The more layers of liquid crystals a product has, the better. However, as they increase, the cost of the welding helmet also increases. Also an important parameter is the weight of the “chameleon”; the mask should not be too heavy.
Brands of welding electrodes and their classification
Welding helmets of this kind are created both at domestic and foreign factories. It is worth mentioning several of the most popular brands: Centaur, Dnepr, Optech, Cosmos, etc.

How to set up a chameleon mask for welding
"Chameleon" is a thing! Ask any welder who has switched to one from a regular mask. You no longer need to take it off every time to look at the work surface, and then put it on with a nod. You can both weld and clean the seam while wearing a mask - this is especially convenient for large amounts of work and welding in hard-to-reach places. Let's talk about this in more detail.
If we talk about the operation of the Chameleon welding helmet in a few words, then everything is simple: when the arc is ignited, the protective screen darkens, thereby protecting the user’s eyes; when the arc goes out, the viewing window becomes transparent again.
It is because of this ability to adapt to changing conditions that it received its name - by analogy with a chameleon changing its color. Welding helmets working on this principle appeared about 25 years ago and were very expensive back then - the process of producing light filters was just developing and was very expensive.
Today, progress has stepped far forward, and “chameleons” have become available to everyone: both professional welders and amateurs.
If you are thinking about buying a “Chameleon” mask for welding work, you probably have many questions. We will try to give as comprehensive answers to them as possible.
What is special about a protective filter?
The Chameleon mask does not have a regular light filter built in, but a liquid crystal filter. It consists of several layers of crystals and layers of vapor barrier film placed between them. When current is applied to the crystals, they become structurized—the light passing through them is blocked. The light filter is powered by a solar battery built into the mask body.
Additionally, many models include lithium batteries. Photosensors on the front side of the product react to the occurrence of an arc - the light filter darkens. When the arc goes out, it returns to a transparent state. The outer side of the glass is coated with a protective compound, which, even when the filter is turned off, prevents the passage of infrared and ultraviolet radiation.
This ensures the welder's eyes are protected at all times.
Is there a risk of “catching the bunny”?
As you know, the glow that appears when the arc is ignited reaches the welder’s eyes in less than a second. Therefore, to effectively protect the eyes, light filters with a response speed from 100 μs to 1/10,000 s are inserted into Chameleon masks. During this time, the screen has time to darken, and the glow from the arc does not blind the person.
By the way, for more effective protection, many models sensitivity . Depending on the lighting of the working area and light interference from heated metal, the degree of protection is adjusted.
You can also adjust the delay time for opening the light filter after the arc dies out, for example, so that the afterglow from the hot metal does not hit your eyes.
Such features of Chameleon welding helmets are important in the professional field; they help make work safer.
Is it convenient to sand and clean the seam in a mask?
The Chameleon light filter is designed to work in two modes: welding (the viewing window is darkened) and grinding (the window is transparent). To process a seam mechanically, there is no need to remove such a mask: the working surface is clearly visible through the glass.
At the same time, the mask provides additional eye protection from flying particles of metal and slag. By the way, to protect the filter itself, an outer glass is provided - this prevents the appearance of scratches and chips on the liquid crystal surface.
The glass is replaceable, so as it wears out and visibility deteriorates, it is replaced.
How do expensive filters differ from cheap ones?
As we said at the beginning of the article, Chameleon masks are now available to a wide range of buyers. This is evidenced by numerous reviews in online stores and discussions on forums. The price range for products is wide. For example, for work in a garage or in a country house there are models that cost about 1,500 – 2,000 rubles, for professional use – up to 3,000 – 4,000 rubles.
What is the difference between them? The quality of filters in budget models is an order of magnitude lower. Such elements are not able to provide adequate protection if the welder is looking at the arc at a large angle. The safe deviation can be up to 10, while for professional ones this value reaches 30.
Inexpensive filters react less well to arcing in dusty conditions, and the response time may increase at sub-zero temperatures. If you have to weld a couple of times a month in the garage, then the listed disadvantages will not be significant for you, but you can save a lot.
In the professional sphere, these aspects will be significant, since the master is exposed to the negative effects of welding every day. You shouldn't skimp on your health.
Want to increase your productivity and protect your eyes while welding? Don't waste time taking off and putting on a mask - spend it working! Buy a Chameleon mask and start cooking in a new way. At heights, above your head, in hard-to-reach places - with this equipment you will be comfortable! You can select and order the appropriate model in the appropriate section of our website.

Additional selection criteria
In addition to the above parameters, the buyer may also be interested in other characteristics:
- The degree of darkening depends on the angle of incidence of the radiation. Good masks should have several layers of quality filters.
- The opening and closing time of the filter should not exceed 2 milliseconds. As a rule, all masks on the market meet this requirement. But during operation, malfunctions may sometimes occur. So, in cold weather, the response time of the filter slows down a little. This feature must be taken into account when working in cold weather.
- The presence of a battery - it is designed to turn the filter on or off.
- Certification – very often welding helmets are designated with the CE symbol. It means that one sample was tested before sales. The DIN marking provides information that the product is tested every two years in the amount of 10 samples. And DIN plus means that the same number of samples pass the test, but every year.
- Arc detection method - in most cases, the optical method is used for Chameleon type welding helmets. To do this, special infrared sensors are installed in the mask.

A welding helmet is a personal protective equipment that is used when welding metal surfaces. Used to protect eyes and face from exposure to ultraviolet radiation, sparks, burns, and infrared rays.
Today there is a wide selection of such masks, differing in shape, size and effectiveness in protecting against the aggressive effects of the welding arc.
The correct choice of a quality product largely determines the safety of work, as well as the long service life of such a mask.
What is a welding helmet?
Any welding mask from a structural point of view consists of the mask itself, worn on the head and a special rectangular window made of polarized lenses, tinted plastic or a special filter with variable density.
Built-in adjustable leather straps ensure a secure fit on the worker’s head, thus preventing it from moving.
When choosing a product, it is important to pay attention to the appropriate size, as well as the type of mask, since many of them also reliably protect the head from accidental impacts, exposure to small debris and dust.

Every welder knows that it is quite difficult to catch a spark in a regular mask, since the welding site is difficult to see through dark glass or plastic.
That is why today Chameleon welding helmets have become very popular, in which the light-protected filter is a special LCD screen, which in its normal state has a light screen, but when an electric arc occurs, it becomes dark. Thanks to this property, using such personal protective equipment is very convenient.

Operating rules
Instructions for using the chameleon welder mask include:
- Before setting up and working, the welder’s mask is carefully removed from the packaging, after which it must be inspected for damage. The protective plates are removed, the protective film is removed from them, after which the panel is put in place. It is important to check the cable.
- Installation and adjustment of the mask. Before starting work, it is necessary to adjust the raising/lowering of the mask using special locking nuts to ensure comfortable and safe work. The welder's mask should fit snugly, not wobble, or interfere with work. Next you need to adjust the angle of inclination. For this, a special limiter is used; the locking nut rotates clockwise, ensuring the mask is raised and lowered to achieve the required position.
- In order for the work to be safe, it is necessary to check the sensors of the light filters, for which the front side of the structure is directed towards a bright lamp. If the viewing window darkens, then the mask is in working condition. You cannot use a mask if the light filters do not work.
- The setup begins with setting the degree of darkness; a special regulator is used for this. The welder's mask can be used for any type of welding work, and only one filter is used; it is enough to set the appropriate degree. After this, the filter delay time is set. There are 2 positions in total, which are 0.15 seconds and 0.8. When setting indicators, you need to pay attention to the afterglow time of the working area.
Setting based on welding mode
Diagram of the front glass of the chameleon mask.
The customizable chameleon welder mask involves the use of several operating modes. There is no need to change filters - you just need to set the required mode. The modes are designated as follows:
- MMA - manual arc welding;
- MIG/MAG - semi-automatic arc industrial welding, designed to work in a gas environment of argon or carbon dioxide;
- MIG (light) - semi-automatic gas arc welding;
- TIG, GTAW - arc welding, for which a non-consumable electrode is used;
- SAW - semi-automatic welding using flux;
- PAC - plasma arc welding.
The instructions also include information about possible breakdowns. In addition to breakdowns, troubleshooting methods are indicated. In case of complex breakdowns, it is best to contact a service center, since the equipment can be damaged, and its further repair will be expensive. If the filter darkens unevenly, you must contact a service center. The filter is out of order, and you can’t fix it with your own hands.
If flickering is observed or there is no darkening of the viewing window, then you need to carefully clean the plate from dirt . If this measure does not help, then it is best to replace the plate, since it is damaged and changing the settings will not help.
If the darkening is uneven, it is necessary to remove the mask and inspect the condition of the sensors. It is important to make sure that the surface of the sensors is not blocked and that nothing prevents light from reaching them.
The chameleon welder's mask should not have any stains of dirt or layers of dust on the surface.
Chameleon mask filter darkening selection table.
Damage to the sensors is indicated by the following:
- filter response is slow;
- the darkening does not go away after the arc goes out;
- flickering is observed, the viewing window does not darken.
In this case, you cannot repair the sensors yourself; you must immediately contact a technician at the service center.
Before starting work, you should always check the condition of the lithium batteries that power the equipment.
For many models, batteries can be easily replaced with your own hands. It is imperative to inspect the sensors, i.e. bring them to a bright light. This is required to ensure work safety, since the lack of darkening leads to eye injuries.
Sensors may be blocked if:
- the window begins to brighten when it is illuminated during operation;
- the dimming level does not correspond to the set mode;
- slow response;
- darkening is observed when there is no longer backlighting;
- flickering is observed.
It is easy to correct this situation: you need to clean the surface of the sensor itself and inspect the condition of the viewing window panel.
How to detect incorrect settings?
The equipment will not perform well if the ambient temperature is too low. For normal operation, it is necessary that the temperature regime be maintained at +15/+55°C. If the equipment is configured incorrectly, the following negative phenomena may occur:
- slow response;
- Dimming the viewing window does not work;
- there is flickering during operation.
It is necessary to adjust the equipment by selecting the correct mode. For this purpose there is a special regulator on the mask body. Before starting work, you should check the mode to ensure that the work is safe. Incorrect settings may also result in the window not being brightened.
Fine adjustments must be made to delay the lightening. For safe and comfortable work, it is important that the mask fits tightly on the head. If this does not happen, then the headband should be adjusted and adjusted.
The safety of a welder largely depends on the ease of use of the mask.
A chameleon type welding helmet is equipment to protect the welder's face and eyes while working. The device differs from a regular mask by the presence of a sensor and an adjustable viewing window. Unlike a regular mask, there is no need to change the glass, since the adjustment is carried out using a special device and sensor, which is located on the front side of the structure.

Why doesn't the darkening work on chameleon welding helmets?
Welding work requires special personal protective equipment. The purpose of a welding helmet is to protect the retina from burns. A chameleon-type mask with an automatic darkening function allows visual control over the ignition of the arc.
Principle of operation
The appearance of the mask is not very different from classic models. The design is as follows:
- A housing that protects the welder from splashes of molten metal and other harmful factors.
- Liquid crystal multilayer light filter with the function of automatic adjustment of the darkening level, depending on the intensity of work.
- Module for setting and controlling the light filter.
- Removable power supply.
A light filter is installed in the viewing glass. It is a device with several liquid crystals. In an inactive state, they do not show themselves in any way - the glass only protects from glare. But when the light sensors signal, the filter comes into operation, rearranging the arrangement of the crystals, darkening the glass. The reaction to the flash is almost instantaneous - about 0.0005 seconds.
[stext id='warning']At negative temperatures, filters operate much more slowly - after 0.001 seconds. However, this does not affect the quality of eye protection, since even this speed indicator is more than sufficient.[/stextbox]
The filter also reacts to the end of work with a delay, the level of which is set manually.
Please note that the design, thanks to built-in filters, provides protection from infrared and ultraviolet radiation even if it breaks.
How to configure correctly, what do you need to remember?
After purchasing a new device, you must study the operating instructions . This will help you figure out how to set up a chameleon mask for welding. Types of adjustments will be discussed later. Now we will give some useful tips to future users:
- Do not use the chameleon for gas or plasma welding or cutting.
- The mask has temperature protection against short-term exposures. If you leave the mask on a hot surface for a long time, it may become unusable.
- The body of the shield is not designed for intense mechanical impact. A strong blow can break it.
- Unauthorized changes to the design of the light filter are not allowed. Disassembling the cartridge yourself may cause damage. When replacing components, use spare parts recommended by the manufacturer.
- Do not use surfactants or solvents to clean the mask. Water getting on the filter is strictly unacceptable.
- Replace power supplies only in grinding mode. Salt batteries are used as removable batteries.
- Immediately after purchase, adjust all available settings to your preferences. Even incorrect adjustment of the fastening straps will result in skin irritation.
Types of adjustments
Regardless of the manufacturer, all models offer a limited selection of operating settings in order to increase comfort and productivity. The following parameters can be adjusted.
Distance from the eye to the filter
Special nuts are responsible for the distance between the eye and the glass. Please note that this indicator should be the same for each eye. Once the adjustment is complete, the nuts are secured.
Darkness level
Adjustable based on welding parameters. The user manual contains a table for selecting suitable indicators. There are two types:
The first type requires stopping welding to remove the mask and set new parameters. Found on amateur models.
The external location of the regulator allows you to adjust the dimming without interrupting production. Used by large enterprises with large volumes of work.
Sensitivity
Adjustment of the chameleon welder’s mask according to this parameter can be configured in two modes:
The first mode will protect vision not only from the arc, but also from all bright light sources, for example, molten metal. Low susceptibility reacts only to the arc.
Semi-automatic welding in an argon environment requires high sensitivity, since this technology has a low current level. There are technological schemes that allow you to select the necessary parameters, depending on the type of work.
Delay time
This function allows you to adjust the duration of the filter after welding is completed. It will be especially useful when using piece electrodes that can stick . If the adjustment is incorrect, the filter will open before the work is completed, which will result in burns to the retina.
Possible faults
Regardless of the manufacturer and quality of the unit, any mask can break. The reasons for failure may be the following:
- Violation of operating temperature conditions.
- Mechanical damage.
- Use of low-quality components.
- End of natural lifespan.
If the operating rules are violated, first of all, they lead to malfunctions of the automatic light filter for the welding helmet. Before contacting official representatives, try to determine the cause of the problem . Some breakdowns can be easily fixed on your own, without the involvement of qualified specialists. Spare parts for repairs can be purchased at points of sale of welding equipment.
The simplicity of the mask design ensures no maintenance problems. A technologically complex device is more difficult to repair.
The mask can be powered either by a solar panel or by batteries. Failure of batteries is the main cause of problems with the chameleon . In this case, the solar cells may simply be discharged. To localize the cause, just leave the device under natural light and then check the functionality. Removable batteries need to be replaced. Replacing the power supply assembly will cost much more.
Problems with glass are visible to the naked eye - external defects in the structure will indicate this. In this case, the filter will not work properly. When replacing LCD glass, it is necessary to comply with the parameters of the element. This is the most expensive part of the assembly.
The biggest problems await the user in case of problems with the control board. In this case, independent repairs, without the involvement of service specialists, are impossible.
Work order
As an example of self-repair, consider the process of restoring a professional device, which, after five years of operation, began to show signs of malfunctioning lithium-ion batteries. The cause of the breakdown was the operating mode - the mask was used several days a year.
Description of the problem: at first the light filter did not work during evening work, while during the day it functioned flawlessly. After some time, the filter stopped working at any time of the day.
The following tools and materials are required for repairs:
- Screwdriver Set;
- Stationery knife;
- Glue gun;
- Lighter or matches;
- Battery holders (2 pcs.);
- Batteries (2 pcs.).
The algorithm of actions is as follows:
