Questions and Answers about Welding Helmets and Goggles
Welding helmet protection is one of the most commonly used attachments in welding operations. If there is no protection device, even the most basic eye protection device, you cannot perform welding operations. But what problems do you need to pay attention to when choosing such protective devices?
Here are some of the most common ones.
Q: What is the current lens cover used in helmets? A: Many people wrongly assume that the lens cover number represents the level of protection provided to the user, so the larger the number, the higher the protection level. This is wrong. In fact, all good-quality helmet lenses have the ability to filter 100% of harmful ultraviolet and infrared rays and provide protection for the eyes. The above number simply represents the degree of transparency provided by that lens and should only be used to measure comfort and visibility data for the user.
Of course, some lens numbers can be used as a guide when you can't be certain that you will choose an appliance for your welding job. These numbers are the same as the amperage of the welding power source.
Always choose the protective lens that will keep you in the best visibility, so as to help improve your welding ability.
Q: The automatic dark-lighting helmet will play a darkening effect when there is a welding arc. Will the alternating light intensity not harm the eyes?
A: In most cases, this is only a personal preference, as long as it provides the welder with convenience.
