Welding helmets are essential and are worn as part of the protective clothing required when welding. Generally, welding is a common process and is used in various industries. Unfortunately, there are so many potential hazards that the process poses with the main ones being electric shock, air contamination, sparks to the eyes, arc radiation and so much more. As such, it is recommended that a welder should always wear a welding helmet so as to avert all these dangers.
A welding helmet is fitted with auto darkening technology, which makes it easier for the welder to prepare the work surface and start welding without a problem. The lens will respond automatically and darken so as to prevent the arc radiation from affecting your eyes. Most In order to make the most of your welding helmet, it would be necessary to understand how it works. There are several components that found in the auto darkening welding helmets which we will look at so that we can understand how they work together.
There three main components that support the auto darkening technology in the welding helmets. The three elements are:
Once you understand all the components and their role, it is very easy to comprehend how the welding helmet works in totality. There are 2 two polarising filters that are near your eye and as you would see, they are arranged in the same orientation. When these filters are not switched on, the light will be twisted to an angle of 90 degrees by the liquid crystals. As a result of this, when you switch off the ADL, the lens will have a dark shade of 5-6, which is a safety feature in itself. This means that even if the ADL malfunctions, you are assured of the protection of your eyes against too much light.
As for the functionality of the ADL, when it is switched on, the first two polarises on the LC panel with un-twist the light waves that have been polarised and the shade is dropped by the lens to shade 3.
There are several things that you should do before using the welding helmet so that it can serve its purpose. The very first thing to do is to set your helmet to the preferred settings. This should be done on a clean surface so as to avoid interference with the lens. Lift the front part of your helmet and check if the battery is in place. After this confirmation, adjust the shield delay time, which refers to the amount of time that your welding helmet will take to change from dark to lighter state. You can use the fast setting to make adjustments of 0.25 to 0.35 seconds or the slower setting of 0.6 to 0.8 seconds.
The traditional welding helmets would require one to keep flipping the visor so as to protect your eyes. However, with the modern auto darkening helmets, you do not need to do this as it will automatically recognize the variation between dark and light. This will be in reference to the eye shield focus. Setting the auto darkening controls may be quite demanding and may overwhelm you. However, here are some of the basic settings:
As you may have realized now, the functionality of your welding shield will depend on the settings that you choose. The location or environment will mostly determine your settings and in most cases, it is advisable to keep it at a default setting of 10. When you are buying your welding helmet, it is imperative to ensure that you get the owner’s manual, which will be useful for purposes of understanding your helmet and the basic functions. This is a safety implement that should be set in the right manner so that it can serve its purpose.
