If your Lincoln Electric Viking 1840 Series welding helmet lens isn't functioning the way it should, the Lincoln KP2853-2 ADF Replacement Kit will renew its normal performance. This kit swaps out a faulty auto-darkening filter cartridge for a new one. Doing so means the lens will properly darken when activated to protect your eyes from damage. Use the KP2853-2 ADF Kit with any Viking 1840 helmet. Call the WeldingMart experts for assistance with installation or to confirm it matches your equipment.
