What to do if my Miller Digital Infinity auto-lens is not switching and stays light?
- OOscar PaulAug 5, 2025
If your Miller Welding Accessories auto-lens stays light during welding or cutting, immediately stop the process and press the On/Off button. Ensure the power is on, then check and adjust the sensitivity settings based on the recommendations. Also, inspect the lens cover and sensors for any obstructions, cleaning them as needed. Make sure the sensors are directly facing the arc; angles greater than 45° might prevent the arc light from reaching them.
