The Lincoln KP3284-1 ADF Replacement Kit is an affordable way to fix a broken or defective helmet lens filter. This OEM auto-darkening filter cartridge for Viking 1740 helmets restores all its normal safety functions. It's a smart investment if the filter has good bad, but the rest of the helmet is still working well. Our official ADF cartridge kit will fit any Lincoln Viking 1740 or Viking 1740 4C welding helmet so you can weld safely.
