10+ Common Questions and Answers about Speedglas Welding Helmets

1.  How to choose a Speedglas welding helmet?

You can choose the right Speedglas welding helmet for your welding project by comparing different models online, reading their reviews and checking the helmet ratings. Some important factors to consider include safety, performance, versatility and of course, comfort.

Knowing the part number for your Speedglas helmet makes it easier for you to buy any spare parts that may be required. You can find the online parts directory directly on the manufacturer’s website, or you can use a free part number finder tool from different platforms online.

3. What are some essential maintenance tips for my Speedglas welding helmet and Speedglas welding respirator?

Whether you have a standard auto-darkening Speedglas welding helmet or a welding respirator, you must change the consumables, worn-out parts and respiratory filters at regular intervals. The frequency of replacement depends on the part in question and the environment in which you typically weld.

4. Why should I choose a Speedglas welding helmet?

Although there are many helmets today that give you the benefit of auto-darkening, Speedglas welding helmets continue to be trusted by welders across the world. This is because its exclusive welding technology is the industry benchmark for other welding manufacturers. By choosing a Speedglas welding helmet, you get comprehensive protection without compromising your comfort.

5. What are the different lens classifications in Speedglas welding helmets?

Welding lenses in Speedglas welding helmets are available in 4 optical ratings. The rating for a helmet is stamped on its lens in the format 1/1/1/1 — where each ‘1’ represents a criterion scored on a scale of 1 to 3. These four criteria are:

  • Light distortion
  • Light diffusion
  • Uniform shading when viewed at a 90-degree angle
  • Uniform shading when viewed at a 15-degree angle

6. How does an auto-darkening Speedglas helmet work?

When a Speedglas auto-darkening helmet is in the ‘safe’ position, the lens is clear. However, the darkening effect kicks in within 0.1 milliseconds of striking the welding arc, protecting your eyes from the sudden brightness. Then, when the welding process is complete, the lens once again becomes clear.

7. What does the number of photo sensors in a Speedglas welding helmet indicate?

Photo sensors in a Speedglas welding helmet detect changes in the level of light in the surroundings, thus triggering the auto-darkening effect when you strike the welding arc. However, it is how these photo sensors are positioned, and not the number of photo sensors, that makes for a good welding helmet.

8. Can I add a PAPR to a non-respiratory standard Speedglas welding helmet?

It is not possible to retrofit the welding mask in a non-respiratory welding helmet into a respirator helmet. However, you can purchase a welding helmet respiratory system without the auto-darkening lens, and retrofit your existing welding lens into it.

9.  What are the different filters that come with the Adflo PAPR helmet?

There are different filters available with the Adflo PAPR helmet, such as the following:

  • The Adflo particle filter, which protects you from particulate contaminants like welding fumes
  • The 3M Adflo gas filter, which captures harmful inorganic, organic and acid gas
  • The Adflo odour filter, which keeps out harmful and unpleasant odours

10.  Who should use an auto-darkening welding helmet?

Auto-darkening welding helmets are suitable for welders of all skill levels, from beginners to experienced professionals. They are especially beneficial for people who frequently perform welding tasks since they offer increased convenience and safety. The auto-darkening feature in Speedglas welding eliminates the need to manually flip the helmet each time, thus providing continuous eye protection during the entire welding process and making it easier to complete the task.


These commonly asked questions about Speedglas welding helmets should help you make an informed decision if you are planning to buy one for your personal welding kit. Take the time to understand the features of helmets on offer and compare the different options to identify the right helmet for your PPE kit.
