First, no matter what kind of helmet you choose, it should be meet or surpass the ANSI Z87.1 – 2003 standards. Such helmets have undergone independent testing and offer protection against impact and also provide 100% protection against the damaging ultraviolet rays. The welding helmets come with a lens of different shades. The shades refer to the ability of the lens to darken the vision. High shade lens are necessary when working with high-amp welding jobs. Choosing low shade for high-amp applications will affect the eyes. Choosing the high-shade lens for low-amp application will hamper the visibility.

A passive lens helmet contains a lens with fixed shade, usually #10. This kind of helmet has the dark-tinted lens that is coated with IR and UV coating. Passive helmets are high economical choice for the welders. However, it also comes with some disadvantages. Passive helmets need to be flipped down and up, between the welding jobs. Some people find very irritating to flip the helmet frequently. The passive helmet should be properly locked into its position. Failure to lock in its place can cause arc flashes striking the eyes.

Auto-darkening helmets do not have the disadvantages associated with the passive helmets. Auto-darkening helmets have lens shade #3 or #4 in a non-activated state to allow you freely see without removing the helmet. The lens shade gets increased upon sensing the welding arc, thereby immediate protection. There is no need for flipping or removing the helmets, when you use the auto-darkening model. Auto-darkening helmets minimize the fatigue and help you complete the job quickly.

Auto-darkening helmets come in two types – fixed and variable. Fixed auto-darkening helmet darkens the shade to the fixed number, say #10. The fixed auto-darkening helmet can be the right choice for welders, who work with the same level of amperage and material type. Variable shade models can darken the lens based on the welding arc intensity.

When choosing the auto-darkening models, you should look into the reaction time of the lens. You should choose lens that can quickly react to the welding arc. The quick reaction results in quick darkening of the lens, thereby offering utmost protection to the eyes. Check the viewing size of the lens. Choose the lens size that allows to offer more range of vision.

Sensors are very important for auto-darkening helmets. These sensors allow the helmet to get activated based on the welding arc.

Not all the welding helmets are created same. By choosing the right welding helmet you will do the welding jobs easily, while staying safe and protected.
