- Protective Film Removal: Remove any protective films from both sides of the inner and outer lenses before first use.

4. Operating Instructions
4.1 Welding Mode
- Ensure the helmet is securely fitted and comfortable.
- Adjust the shade knob on the side of the helmet to the desired shade level (9-13) based on your welding process and amperage. Refer to standard welding shade charts for guidance.
- When the welding arc is struck, the lens will automatically darken to the selected shade. When the arc ceases, the lens will return to its light state.
4.2 Grind Mode
- To activate grind mode, locate the 'Grind' knob on the side of the helmet and turn it to the 'Grind' position.
- In grind mode, the auto-darkening function is deactivated, allowing for clear, unobstructed vision for grinding or cutting tasks.
- Important: Always switch back to a welding shade setting before initiating any welding operations.
5. Maintenance
- Cleaning: Regularly clean the helmet shell with a mild soap and water solution. Avoid harsh abrasives or solvents.
- Lens Care: Clean the inner and outer protective lenses with a soft, clean cloth and a non-abrasive lens cleaner. Replace scratched or damaged lenses immediately.
- Storage: Store the helmet in a dry, clean environment away from direct sunlight and extreme temperatures.
- Battery Check: The auto-darkening lens is solar-powered with a backup battery. Ensure the solar cells are clean and exposed to light regularly to maintain charge.
6. Troubleshooting
- Lens Not Darkening: Check if the helmet is in grind mode. Ensure the solar cells are clean and exposed to light. Verify the ambient temperature is within the operating range.
- Poor Visibility: Clean the protective lenses. Ensure the correct shade level is selected for the welding process. Replace scratched or damaged lenses.
- Uncomfortable Fit: Adjust the headgear straps and tilt mechanism until a comfortable and secure fit is achieved.
