The Tolsen 45087 is an industrial auto-darkening welding mask designed to protect your eyes across various processes, including ARC, TIG, MIG, and plasma cutting. It features a large 92 x 42 mm viewing area that ensures clear visibility while maintaining a high level of safety. The filter switches from a light state of DIN 4 to a dark state between DIN 9 and 13 in just 1/25,000 of a second, which prevents flash burns during the start of a weld. To help you tailor the mask to your specific environment, it includes an external shade knob and adjustable settings for both sensitivity and delay time, ranging from 0.2 to 0.8 seconds. The housing is constructed from flame-retardant PP material for added durability in harsh industrial settings. Power is managed automatically through a combination of solar cells and lithium batteries, so you can focus on your work without worrying about manual switches. This CE-approved equipment is a practical choice for professionals who need reliable, adjustable protection for long hours of welding.
