Whether you're working in the garage or on the actual job site, every welder must invest in a good quality welding helmet to increase comfort and protect the eyes from damage, as well as achieve welding ability improvement resulting in good quality welding output and ensuring your safety. If you are not familiar with the latest in auto-darkening lens technology as well as national safety standards, choosing the right welding helmet can be confusing.

There are different welding helmet lens types namely standard or passive lens welding helmets and viewing or filter lens welding helmets. The standard or passive lens welding helmets are made from molded plastics, providing basic protection that were made of thick leather fifty years ago. The viewing or filter lens welding helmets are made of special dark tinted glass with infrared and ultraviolet coatings at #10 shade. Auto-darkening filters (ADF) are embedded with electronic filter lens equipped with features that are adjustable to make welding easy and simple. Auto-darkening filter lens is specially made of LCD or liquid crystal display which is similar to the technology used in displaying numbers of a digital alarm clock, mostly powered by combining solar power and battery. Near the lens, there are several light sensors to detect the welding arc, and when the lens is not on active mode, an auto-darkening LCD filter has #3 or #4 shade, seeing through like using a sunglasses. In this way the welder will be able to see the position of his MIG gun, stick electrode or TIG torch in relation to the material being welding. The auto-darkening filter welding helmet has built-in sensors to darken the shade of the lens into #9 up to #13 once an arc has been initiated, basing on your settings which is hundred times faster than you are able to blink your eyes. The eyes have protection against harmful rays whether you're in active or inactive shade setting owing to its ultraviolet and infrared coatings. Auto-darkening welding helmets stays down all throughout the welding job, unlike the old welding helmet standard version wherein you have to do head snaps to lower the welding helmet, making sloppy starts because of the torch being moved.

A fixed shade #10 is enough for welding involving one type of material like steel, with the same thickness and welding process. However if you are most people who weld various materials such as stainless steels, mild steel and aluminum, with different thickness and welding processes, like stick, TIG and MIG for a specific use, you'll need a variable or adjustable shade lens type varying from 40 amps up to no more than 200 amps.
