The outside shell of the helmet protects the wearer’s forehead, face, and neck from risks while welding.

Its auto-darkening lens function provides eye and vision safety and senses arcs easily when used according to the manufacturer’s specifications.

Even when regularly exposed to high heat from welding, this helmet does its job with great success. The included filter also withstands heat well and refrains from melting, even under extreme conditions.

Ease of Transportation

Weighing just one pound with all included items attached, this welding helmet remains easy to pick up, move, carry, and transport from place to place.

When used with a carrying or storage case (sold separately), it becomes even easier to work with.

This welding helmet also provides comfort and ease of use. It remains light enough to wear during several hours of welding work without needing to take a break.

Its included headgear keeps it on securely without causing undue pain or stress on the wearer’s body or head.

Who Should Buy the Speedglas 100?

The Speedglas 100 welding helmet comes with plenty of built-in features to improve safety and functionality.

However, it lacks some of the higher-end bells and whistles that come with other brand name auto-darkening helmets.

This helmet provides maximum safety and security for any user and sense arcs across three types of welding processes.

It works especially well for beginners who need a durable helmet but do not want something too overwhelming.

Home hobbyists and part-time welders also enjoy working with this auto-darkening helmet. It brings plenty of functionality to any home welding setup.

Our Recommendation

The Speedglas 100 welding helmet combines beginner-friendly features with a high optical rating and plenty of viewing space.

The result makes MIG, stick, and TIG welding safer and easier for welders of all skill levels.

We recommend this welding helmet for beginners in need of a lightweight helmet for safety that does not include too many complicated settings or functions.

We also recommend it for home hobbyists who weld infrequently.
