Operating a welding machine, whether gas or arc welding, produces light that is unsafe for your eyes. A few seconds of contact with arc lighting can seriously damage your eyesight, and looking into a gas torch flame can cause similar damage. Therefore, protective eyewear is absolutely essential when welding.
The first question to look for when purchasing a welding cap is which lenses are right for you. The typical or passive welding cap is as familiar today as it was 50 years ago. Although currently made of molded plastic as an alternative to thick leather-based, these helmets offer critical safety at a budget cost.
The viewing mirror is usually a special piece of dull colored glass, often with a number 10 shade as well as ultraviolet (UV) and infrared (IR) coatings. At what point is the welder ready to start welding, it's faster to quickly nod or break the helmet with the neck than to cross the arc. When finished, the welder reaches up and turns the helmet upward, then flips it back to view the working parts and reposition it for the next weld.
While reasonably priced, regular helmets have many drawbacks. After lowering the helmet into place, it is often difficult to keep the torch in the correct spot to begin welding, especially for novices. When welding in a restricted space, similar to under a car or trailer, there is not enough room to flip the helmet up and down. The never-ending work of flipping up and down leads to a restless collar after a day of welding. Also, as a final point, lifting and lowering the helmet is inefficient, especially when doing a lot of spot welding.
Automatic darkening of the welding cap solves all these problems. As an alternative to the regular part of tinted glass, helmets with auto-darkening filters contain electronic filters and are sometimes preloaded with adaptable features to make welding painless.
The auto-darkening filter lens is a special liquid crystal display (LCD) designed to be comparable to the devices used to display digital alarm clock numbers. In most cases, the cartridge is powered by a combination of batteries and solar energy. A number of illumination sensors are installed near the lens to notice the welding arc. Although the lens is not activated, the auto-darkening LCD filter usually has 3 or 4 shades that are relatively easy to view, just like a sunshade.
This makes arc initiation better because you are able to see the position of his MIG gun, TIG torch or other welding rod relative to the material he is welding. Once the arc is initiated, the sensor in the helmet causes the lens to dim to a shade of 9 to 13, depending on the option, countless times faster than you can blink. Since the filtering system has UV light in addition to the applied IR coating, the eyes are protected from harmful rays regardless of the active/inactive shade setting. Most importantly, the helmet stays down before and during the completion of your duties. Auto-variable welding caps allow you to set up welds with the hood in place. No more head snaps to lower the helmet. No more bad welds since the torch was moved.
