The Lincoln Electric KP3046-150 Cheater Lens is a 1.50 magnification drop-in lens designed to improve clarity for close-up welding and fit-up work. Measuring 2" high x 4.25" long, it is compatible with most welding helmets that accept standard cheater lenses, helping reduce eye strain and improve visibility of the puddle and joint line. Ideal for detail work, inspection, and precision tasks where a sharper view makes a difference.
