【Safety & Protection】combined with auto dimming LCD shutter, providing sufficient and accurate shade range within 3/5-9/9-14 or other higher range to visible light

【Comfort & Convenience】more comfortable to have a clear view of joints and weld puddle, getting better control on the whole welding process and beautiful beads finish; Inside shade setting with memory settings to avoid accidental changes and great to be used in tight spaces

【Performance】detecting and controlling units providing super-fast switching time and accurate auto shading, minimizing harmful radiant bypass, avoiding eye stress

【Reliability】Interference Suppression Technologies, minimizing false triggering: less sensitive to sun lights, workshop lights while very responsive to welding arc, even the hardest to detect DC TIG; Corner spread arc sensors provides more coverage, reducing blockage in complicated welding positions

【Versatility】A great auto dim lens that can handle multiple processes of Plasma Cutting, abrasive wheel cutting/grinding, DC TIG, AC TIG, MIG/MAG, MMA/Stick welding, which are popular in metal fabrication industry, welding schools, welding shops, auto manufacturing and repair industry, ship factories as well as DIY hobbyists projects
