A right welding helmet is essential for both professional welders and amateurs. Many welders prefer traditional helmets. These passive helmets are cheap, but each time you inspect a weld, you have to lift the helmet and then re-secure it. Therefore, repeating this action hundreds of times in a day will take a lot of time and energy.

An auto-darkening welding helmet is the best choice. Not only does it prevent harmful light emissions, but it also senses the brightness of the welder and then dims within milliseconds to protect your vision. Therefore, you need no longer lift or completely remove the helmet. In addition, the wide view auto-darkening welding helmet adds comfort and efficiency.

Good auto-darkening welding helmets protect your face and eyes while ensuring comfort. They are essential in construction, automotive, manufacturing, etc. Today, 3M, Lincoln Electric, Miller Electric, etc., are leading brands. LumBuy also offers a variety of brands to meet your needs.


An auto-darkening welding helmet is also known as an auto-darkening welding hood, an auto-dimming welding helmet, or a self-darkening welding helmet. It prevents harmful light emissions and senses the brightness of the welder and then dims within milliseconds to protect the welder's vision. Usually, there are two types: solar-powered auto-darkening welding helmets and battery-powered auto-darkening welding helmets.

The auto-darkening welding helmet price range from $100 to almost $3000. Which is best depends on which features you need. Do you need automatic darkening or passive shading, or other features? You need to consider these issues. Some high-end helmets are equipped with powered air-purifying respirators (PAPR), perfect for environments without ventilation.

  • Lens Response Time
Buy an auto-darkening welding hood in line with CSA Z94.3 and ANSI Z87.1 standards because even if the lens does not darken, it still provides effective eye protection. High-quality helmets are dimmed within milliseconds to ensure comfort. If you don't weld often, a lens reaction time of 1/3,600 seconds is fine. But if you do welding all day, choosing a faster reaction time is recommended. 1/20,000 second lenses are more comfortable, even for long working hours.

  • Variable shade & fixed shade lenses
Some auto-darkening welding helmet lenses will automatically darken to shade 10. If the type of welding remains the same, this auto-darkening welding helmet is ok. If you change between TIG and MIG, you need a variable shade auto-darkening welding hood, whose shade range is usually between 9 and 13. It will still work well even if the brightness of the arc changes.

  • Adjustable delay & sensitivity control
Some helmets do not support sensitivity and delay control. Other arcs will trigger the helmet's response if you are working with other welders. In addition, for TIG welding, lower amperage may not trigger the helmet.

It is also important to adjust the delay, which allows you to adjust how long the lens stays dark. Higher current welds lend themselves to longer delays (one second). For tack welding, shorter delays are better.

  • Observation size & sensors
Larger viewing area sizes are better because you can see better for large welded assemblies. Some inexpensive auto-darkening welding hoods have only one or two sensors. An auto-darkening welding helmet with four sensors is usually good. Two sensors sometimes do not recognize the flash. However, a four-sensor one can sense any flash.

  • Control panel & power
Usually, there are batteries and solar panels. Some use both. The last is the best because solar panels extend the battery's life.

External control panels allow you to change settings while not having to move the auto-darkening welding hood. However, they may be more vulnerable to damage. Internal controls are less likely to be damaged but less friendly when adjusting settings.

It can sense how much light the arc emits and activate the liquid crystal filter electronically to dim to a preset shade, freeing the welder's face and eyes from ultraviolet and infrared radiation.

  • Adjust the delay time
Depending on the type, the delay time can be as fast as 0.25 to 0.35 seconds and as slow as 0.6 to 0.8 seconds. You should adjust the delay time according to your personal preference. Many auto-darkening welding hoods allow you to adjust the delay time by moving an internal switch.

  • Adjust shade settings
Many helmets have a knob located on the left side. Welders adjust the darkness according to the type of weld. It is recommended to use the darkest shade recommended for a particular type of weld. Then, change the headband and angle until you can see through the helmet. In addition, you will need to test the automatic shade. If the helmet is set up correctly, it will darken even if there is no arc. If it does not dim completely, do not use the helmet.

  • Check battery
Before replacing the battery, you better determine if a dead battery is the reason the helmet stopped working. Depending on the helmet model, there are several ways to check the battery. The helmet's light signal lets you know when it's time to replace the battery.

If the auto-darkening welding hood can automatically dim, try putting it on at different intensities to check if the battery is ok. You can also take the helmet outside.

  • Prepare materials
Here are some common materials.

  • Figure out where the batteries are
The owner manual lists the location of the batteries. However, not every owner's manual includes this. The battery is usually in the front of the housing. Once you find it, you should dig in with the Dremel tool.

  • Cut out the plastic part
You will need to cut out the piece of plastic that covers the battery. After that, you should take a picture of the battery setup to install the new battery later.

  • Remove the battery
The battery should be held in place by several tabs. You use a screwdriver or pliers to loosen these tabs and then carefully remove the battery.

  • Install a new battery
Please connect the correct polarity to the right end. A photo taken earlier should help you determine the location. You connect the new lead to the new battery.

  • Find the second battery
There is usually one more battery. If you are lucky, it is close to the first battery. After you find it, replace it with a new battery. However, some helmets may not have a second battery. The instruction manual should have information about it. If not, you can try testing the helmet.

  • Put the helmet back together
Now, you need to secure the parts together. The glue comes in handy at this point. If you have the time and patience, epoxy will work.

  • Test the helmet
After changing the battery, testing the helmet is a must. You can take it out into the sunlight to see if the lenses darken.

For solar helmets, sunlight charges the photovoltaic cells. Some helmets are powered by solar energy and batteries. Solar energy provides additional power to the internal battery of the helmet. Therefore, the helmet does not need to be charged with power. And this helmet can be used when it is not in the sun.

As long as you take care of them properly, you can use most helmets for about 7 to 10 years. It's mostly to do with the sensors and lenses since some helmet lenses and batteries can be replaced.

You can take the helmet outside, stand for a few minutes, and keep the sensor facing the sun. Then, you can see if the lenses darken. If the lens gets dark, it's a good helmet.

Since temperatures below freezing have an effect on the reaction time of the lenses, do not leave your auto-darkening welding helmet in the garage, shed or truck during the winter. Otherwise, the life of the lenses will be shortened.
