Using this replacement ADF cartridge is easy. First, turn off your Lincoln Electric VIKING 3350 ADV welding helmet. Then, carefully remove the old cartridge. Align the new KP3045 - 5 cartridge correctly and place it in the slot. Make sure it fits snugly. When using the helmet with the new cartridge, keep it away from extreme heat or moisture. For maintenance, clean the cartridge gently with a soft, dry cloth. Avoid using harsh chemicals. If you notice any issues with the cartridge, like blurry vision or inconsistent performance, stop using it and contact customer support.
