  • Perfect 1/1/1/1 Optical Clarity - This rating is determined by measuring blurriness, distortion, shade consistency and angle uniformity of the auto-darkening welding lens
  • Extra Large Viewing Area - The 12.5 square inch auto darkening lens provides a large field of view to increase versatility and operator control
