No matter what you are working on, it is definite that you have to prioritize your safety whenever you weld. This includes keeping every corner safe from inflammable materials and using the appropriate equipment for welding. Apart from welding gloves and fire resistant jacket, welding helmet is another important tool that is made to protect welders’ eyes from the intense flash since it can result in blindness. If it is your first time getting a welding helmet, it can be confusing to choose what will suit you the best. There are some considerations that should be taken when buying a welding helmet and this article will guide you through it.
The most noticeable feature in welding helmets is the glass lens that protects the welders’ eyes. In order to repel the bright flash from the arc, these lenses are tainted in a black shade. Standard lenses only provide a single shade, but auto-darkening lenses can adjust it to multiple levels depending on the brightness of the flash using light sensors.
Lens Reaction Speed
When you are looking for helmets with an auto-darkening lens, they usually come with different reaction speed, which is mentioned in the user interface. Entry-level helmets usually have the speed of 1/3,600 seconds while the advanced ones are at 1/16,000. Advanced helmets are much pricier, but it is worth the price since the faster reaction will significantly reduce the eye strain caused by the flash.
It is even better if you can adjust how long an auto-darkening lens will stay dark after the arc stops since it will be more comfortable for your eyes. This feature usually only come along advanced welding helmets and can be turned on and off.
Auto-darkening helmets can work because of an energy source, which can be replaceable batteries or solar power. The downside of using solar-powered helmets is that they will take some time to recharge the energy under the sunlight. Battery-powered helmets, on the other hand, can be immediately used as long as you exchange the battery whenever it runs out of power.
