2. Safety Information
WARNING: Read and understand all safety instructions before using this welding helmet. Failure to do so may result in serious personal injury or death.
- Always wear safety glasses under the welding helmet.
- Do not use this helmet for overhead welding applications unless specifically rated for it.
- Do not use this helmet if the auto-darkening function is not working correctly. Immediately replace any damaged parts.
- Protect the lens from scratches and impacts. Scratched lenses reduce visibility and compromise protection.
- Ensure the helmet is properly adjusted to fit your head securely before welding.
- Avoid direct exposure to welding arc without proper eye protection.
- This helmet is not suitable for laser welding or oxyacetylene welding/cutting applications.

4. Product Features
- Ergonomic Flip-up Design: Allows the user to lift the auto-darkening filter for non-welding tasks without removing the entire helmet. The helmet shell is constructed from high-impact-resistant nylon, suitable for temperatures from 14°F to 149°F (-10°C to 65°C).
- Digital Welding Lens: Provides precise control over shade, sensitivity, and delay settings. Features memory function for customized preferences.
- Large Viewing Area: Main viewing window measures 3.94" × 2.34" (100mm x 59.4mm). Includes side view panels (DIN5, non auto-darkening) for enhanced peripheral vision. Features 1/1/1/1 optical clarity and true color technology for a clear and natural view of the weld puddle.
- Fast Auto Darkening: Equipped with 4 advanced arc sensors, the lens switches from light to dark in 1/30,000 seconds, offering immediate protection against harmful UV/IR radiation.
- Versatile Application: Suitable for various welding processes including STICK, MIG, TIG, as well as grinding and cutting operations.
- Extended Service Life: Features a solar panel on the front and an integrated rechargeable battery. The solar panel contributes to power, reducing reliance on the internal battery and extending its overall lifespan.

5. Setup
5.1 Headgear Adjustment
- Fit the Headgear: Place the helmet on your head. Adjust the top strap to ensure the helmet sits comfortably and securely.
- Adjust the Headband: Use the ratchet knob at the back of the headgear to tighten or loosen the headband until it fits snugly without being too tight.
- Adjust Viewing Angle: Use the side knobs to adjust the tilt of the helmet and the distance between your face and the lens. Ensure a clear and comfortable viewing angle.
5.2 Protective Lens Installation
Ensure both inner and outer protective lenses are clean and free from scratches. Replace them if damaged.
- Outer Lens: Slide the outer protective lens into the designated slot on the front of the helmet.
- Inner Lens: Place the inner protective lens inside the helmet, securing it in its frame.
6. Operating Instructions
6.1 Powering On/Off
The helmet is equipped with an automatic power-on/off function. It activates when exposed to light and deactivates after a period of inactivity.
6.2 Digital Lens Adjustments
The digital welding lens allows for precise control of welding parameters:
- Shade Control: Use the "SHADE" button to cycle through or adjust the desired shade level (4/5-9/9-13). Refer to welding standards for appropriate shade levels for your application.
- Sensitivity Control: Use the "SENSITIVITY" button to adjust the lens's sensitivity to arc light. Higher sensitivity is suitable for low amperage TIG welding, while lower sensitivity helps prevent false triggering from ambient light.
- Delay Time: Use the "DELAY" button to set the time the lens remains dark after the arc stops. A longer delay is useful for high amperage welding to protect against afterglow.
- Mode Selection: Use the "MODE" button to select between welding (TIG, MIG, ARC) and grinding modes. In grinding mode, the auto-darkening function is deactivated, and the lens remains in a light state (shade 4).
6.3 Flip-up Mechanism
To perform non-welding tasks (e.g., inspecting welds, preparing materials) without removing the helmet, simply lift the front flip-up section. The clear inner visor provides eye protection during these tasks.

7. Maintenance
7.1 Cleaning
- Helmet Shell: Clean the helmet shell with a mild soap and water solution. Avoid harsh solvents.
- Lenses: Clean protective lenses and the auto-darkening filter with a soft, clean cloth and a non-abrasive lens cleaner. Do not use abrasive materials or solvents that could damage the lens coating.
- Sensors: Keep the arc sensors on the front of the auto-darkening filter clean to ensure proper function.
7.2 Lens Replacement
Replace outer and inner protective lenses regularly, especially if they become scratched, pitted, or otherwise damaged. Refer to the helmet's design for specific instructions on how to remove and install new lenses.
7.3 Battery Charging
The helmet features an integrated rechargeable battery, supplemented by a solar panel. If the battery level is low, connect the provided charging cable to the helmet's charging port and a suitable USB power source. The solar panel will also charge the battery when exposed to sufficient light.
