When most people hear the word 'solar,' they think of something powered by the sun. This is a common misconception when it comes to auto-darkening helmets. Let’s uncover the truth about solar-powered welding helmets and help you decide if they’re the right choice for your workshop.

 

How Solar Powered Helmets Work

Solar-powered auto-darkening helmets utilise both solar and battery-generated power. Initially, the battery powers the mask or hood as you strike the welding arc. Once the arc is activated, the UV light generated powers the solar panel in the hood, which then powers the electronics. So no, you don’t need to stand in a sunny spot to get the job done!

Why Use a Solar Powered Helmet?

Solar-powered helmets offer several advantages:

  • Lightweight Comfort: Typically lighter, making them more comfortable for all-day wear.

  • Battery Life Preservation: The solar power takes on most of the workload, extending battery life.

  • Economical: More cost-effective than fully battery-powered helmets in the long run.

  • Convenience: Many high-quality helmets feature an auto-off function to save battery life if you forget to turn it off. Pro tip: switch to grind mode when not in use for extra savings.

What Kind of Batteries Are Best?

Choosing the right battery type can significantly impact your helmet’s longevity and performance:

Older Models

Older helmets often have fixed batteries that can’t be recharged or replaced. While these may be cheaper initially, you’ll likely need to replace the entire helmet within 1-3 years.

Newer Models

  • Replaceable Lithium-Ion Batteries: These typically last 1-2 years and can be easily swapped out when needed. Keep spares on hand to avoid downtime.

  • Rechargeable Fixed Batteries: Some premium helmets, like the Jackson WH70, feature rechargeable fixed batteries. With a long lifespan and no need for replacements, these helmets are a reliable option—just ensure they come with a good warranty.

Pros and Cons of Solar Powered Helmets

Pros

  • Economical: Solar panels harness energy from the welding arc light, conserving battery life.

  • Can be charged by sunlight.

  • Auto-off functionality helps save battery life.

  • Lightweight and comfortable for extended use.

  • Versatile for various operations.

Cons

  • Older models with non-rechargeable batteries only last 1-3 years.

  • Batteries may need charging before use.

Things to Consider

  • Battery Type: Replaceable batteries are great for reliability and longevity. Keep spares on hand for convenience.

  • Rechargeable Batteries: Excellent for top-quality helmets—just ensure a solid warranty backs them.

  • Charging Time: Plan ahead to ensure your helmet is charged before welding.

  • Auto-Off Functionality: This feature is very useful for those that forget to turn their helmets off!

With these insights, you’re now equipped to make an informed decision about solar-powered auto-darkening helmets. Whether you prioritise battery life, comfort, or cost-effectiveness, there’s a helmet out there that’s perfect for your needs.
