3. Setup
Before using your welding helmet, perform the following setup steps:
- Unpacking: Carefully remove the helmet from its packaging. Inspect for any shipping damage.
- Headgear Adjustment:
- Adjust the top strap to position the helmet correctly on your head.
- Rotate the knob at the back of the headgear to tighten or loosen the fit around your head until it is snug but comfortable.
- Adjust the distance between the helmet and your face using the side knobs to ensure the viewing area is centered and clear.
- Battery Check: The helmet includes batteries. Before first use, ensure the batteries are properly seated and functional. The helmet is solar-powered with battery assist, so direct sunlight or bright light can help charge the solar cells.
- Function Test: Before welding, perform a function test. Point the helmet towards a bright light source (not the sun or a welding arc) and observe if the lens darkens momentarily. This confirms the auto-darkening function is active.

4. Operating Instructions
Follow these steps for safe and effective operation of your auto-darkening welding helmet:
- Pre-Weld Check: Ensure the helmet is properly fitted and the auto-darkening function has been tested. Verify the lens is clean and free from scratches.
- Positioning: Place the helmet on your head, ensuring the viewing area is aligned with your eyes. In its light state (DIN 4), you should have clear visibility of your workpiece.
- Initiating the Arc: Begin your welding operation. As soon as the welding arc is struck, the auto-darkening filter will instantly switch to its dark state (DIN 11), protecting your eyes from intense light.
- Post-Weld: Once the arc is extinguished, the filter will automatically return to its light state after a short delay, allowing you to inspect your weld without removing the helmet.
- Grinding Mode (if applicable): This specific model has a fixed shade 11. If grinding is required, use separate appropriate eye and face protection.
5. Maintenance
Regular maintenance ensures the longevity and proper function of your welding helmet.
- Cleaning the Lens: Clean the outer and inner protective lenses regularly with a soft, clean cloth. Do not use abrasive cleaners or solvents.
- Cleaning the Helmet Shell: Wipe the helmet shell with a damp cloth. Avoid harsh chemicals.
- Battery Replacement: While the helmet is primarily solar-powered, it uses internal batteries for assist. If the auto-darkening function becomes inconsistent or fails, replace the internal batteries according to the instructions provided on the battery compartment (typically located within the ADF cartridge). Use only the specified battery type.
- Storage: Store the helmet in a dry, clean environment, away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect all parts for wear and tear, including the headgear, protective lenses, and the auto-darkening filter. Replace any damaged components immediately.
