Using this welding helmet is easy. First, adjust the 3 - point pivot headgear to fit your head comfortably. Make sure the front and rear sweatbands are in place to reduce pressure. Turn on the auto - darkening function if you need it. You can adjust the shade, sensitivity, and delay according to your welding process. When using the grind mode, the LED indicator will let you know it's working. Remember, the helmet is powered by solar cells, but you can also use AAA batteries, which are easy to replace. As for maintenance, keep the lens clean. You can use the extra cover lenses included in the package. If the helmet gets dirty, wipe it gently with a soft cloth. And don't forget, it comes with a 5 - year no - hassle warranty, so you're covered for a long time.
