Can safely be used with appropriate welding masks for most welding applications.

There are two main types of welding mask- those that have a fixed-darkness viewing portal, and those that have an auto-darkening viewing portal. Fixed darkness usually have a flip-up face shield, so that you can see normally when you are not welding, and then nod your head to put the mask in place once you are ready to weld.

Auto-darkening helmets use a polarizing filter that automatically prevents harmful flash burn to the user. This has the advantage that the wearer does not have to adjust their helmet for working, saving them time and effort. As they do not need to be adjusted, they reduce the risk of exposure to harmful light.

The main disadvantage of a darkening welding helmet is that they are often more expensive than their fixed-darkness counterparts. It is important to choose the welding mask that is best suited to the job at hand.
