Certified welding filter in the highest optical class 1/1/1/1 with a large field of view of 100x60 mm and protection against UV/IR rays at the DIN 16 level. The glass made of durable polycarbonate protects the filter against splinters. Four arc sensors and precise electronics will detect an electric arc from TIG with an intensity of only 5A. The filter is powered by a solar cell and two replaceable CR2450 batteries. The visor has a smooth adjustment of the degree of darkening, sensitivity to the intensity of the light source, as well as the duration of maintaining the dark state after welding. The button on the filter turns off the dimming function, then you can use the helmet as a means of personal protection, e.g. against sparks from cutting or grinding metal. A four-point harness, sweatband, size and working angle adjustment system guarantee high comfort and adjustment of the helmet position to individual requirements. Auto-darkening filters in YATO welding helmets have a Test button that allows you to check the operation of the auto-darkening function before starting welding. A routine of checking the filter for proper operation each time will help protect the operator's eyes and health. filter type: auto-darkening, true color optical properties: 1 / 1 / 1 / 1 field of view: 100x60 mm filter size: 133x114 mm response time: 1/25000 s brightening time: 0.2-1 s number of arc sensors: 4 dark state: 5-9|9-13 DIN light condition: 4 DIN filter test sensitivity adjustment dimming adjustment power supply: solar cell, 2 pcs.
