Miller recently added a new set of digital features to their Elite series of auto-darkening welding helmets. The new masks include settings for welding, cutting, and grinding, as well as an “X-Mode” setting that electromagnetically senses an arc and then automatically switches to a predetermined shade level, with a reaction time of 1/20,000 of a second. The X-Mode setting also prevents sunlight or an obstructed sensor from causing interference.
Set the mask for grinding to ensure that only a #3 shade is used when the light-sensitive sensor detects sparks. The cutting setting darkens the mask to shades #5-8, and the welding setting filters even more light with shades #8-13. The mask weighs in at 18 ounces and features an adapter for a magnifying lens. Two lithium batteries will run it for 3,000 hours.
You can get it in basic black for about $275, or throw in another $20 for a model with more decoration.
