Welding Helmets, Hoods & Masks

Q: Can you tell me what to look for in a welding helmet?

Q: How does an auto darkening welding helmet work?

A: An auto darkening helmet uses sensors to detect when a welding arc is present. When detected, it activates polarization filters and liquid crystals to almost immediately account for the glare. This is different from a passive welding helmet, which has a single shade of lens.

The advantage of an auto darkening helmet over a passive helmet is that the welder retains their vision without having to deal with a blinding flash. An auto darkening helmet can respond within thousandths of a second upon activation, which means your eyes don't have to adjust. This may seem like a convenience to most people, but welders realize the dangers of holding an active welding arc without being able to see it, even for a second or two.

Auto darkening helmets also have safety features for ensuring vision protection in case the sensors fail, rooted in how the polarizing filters are aligned. They are built to offer set-it-and-forget-it power, letting welders concentrate on their work.

A feature to consider is the difference between a fixed shade or variable shade. A fixed shade will activate to one shade level upon arc activation, while a variable shade can adjust to a lighter or darker shade based on your project.

Q: What is a passive welding helmet?

A: A passive welding helmet is equipped with a shade that does not adjust its darkness level. While passive welding helmets are built for safety and protection, they use the same principle as solar eclipse sunglasses - when worn, you will see light sources bright enough to pass through the lenses. The fixed level of darkness means that means that a welder will have to remove the helmet in order to properly inspect their welds.

Passive helmets are a good option for simple welding projects, as well as grinding or other tasks that create sparks. They tend to be lightweight and easier to wear, as well as less expensive, but they are not equipped to handle more advanced or professional welding projects.

Q: What is the best welding helmet?

Q: How do I clean a welding helmet?

A: Carefully, and with consideration of its different components. The most important component is the lens. Glass cleaners are good for cleaning the lens, as well as soap and water, for initial cleaning. But eventually, the smoke and spatter, as well as the dust, debris and scratches that come from working, will take their toll. Advanced cleaning methods include using a buffing wheel, a rubbing compound or polish.

Avoid using a loose towel, T-shirt or your hand to clean off your lens. Doing that runs the risk of causing more scratches.

Interior components that absorb sweat may be removable in order to wash them with the laundry. In general, avoid submerging your helmet - especially if there are electrical components.

Whatever helmet you buy should come with some manufacturer's recommendations for proper cleaning.
