The Neilsen CT0529 auto - darkening welding mask offers an incredibly fast darkening speed of 1/10000 second. It features an automatic power on - off function for convenient use. With a wide viewing angle, it allows welders to have a better view of their work. This mask requires 2 x AAA batteries (not included).


Using this Neilsen welding mask is easy. First, insert 2 AAA batteries into the designated slot (note that the batteries are not included). Once the batteries are in, the mask will automatically turn on when it senses welding light and turn off when the light stops. When welding, place the mask firmly on your face to ensure a proper fit and protection. Make sure the wide viewing angle is adjusted to your preference for a clear view of your work. For maintenance, keep the mask clean by wiping it with a soft, dry cloth after each use. Avoid exposing the mask to extreme temperatures or rough handling. If the mask doesn't darken as quickly as it should, check the batteries and replace them if needed.
