Safety Information
Welding operations involve inherent risks. Always follow safety guidelines to prevent injury. This helmet is designed to protect your eyes and face from arc flash, sparks, and harmful radiation during welding. It is not suitable for laser welding or overhead applications where falling objects are a hazard.
- Eye Protection: Always wear appropriate primary eye protection (safety glasses) under the welding helmet.
- Ventilation: Ensure adequate ventilation to avoid inhaling welding fumes.
- Inspection: Inspect the helmet and lens before each use for any damage. Replace damaged parts immediately.
- Temperature: Do not expose the helmet to extreme temperatures.
- Cleaning: Clean the lens with a soft cloth and mild cleaner. Do not use abrasive materials.

Setup
- Unpack: Carefully remove the welding helmet and all accessories from the packaging.
- Inspect: Check the helmet for any signs of damage during shipping. Ensure the protective films are removed from the lenses.
- Charge Battery: Connect the helmet to a USB-C power source to ensure the rechargeable battery is fully charged before first use. The solar panel will help maintain the charge during use.
- Adjust Headgear:
- Place the helmet on your head.
- Adjust the top strap (3) to position the helmet correctly on your head.
- Use the front/back adjustment knob (2) to move the helmet closer or further from your face.
- Tighten the tightness adjustment knob (7) at the back to secure the headgear comfortably.
- Ensure the helmet is stable and the viewing area is centered with your eyes.
- Test ADF: Before welding, press the "TEST" button on the control panel to verify the auto-darkening function. The lens should darken momentarily and then return to its light state.

Operating Instructions
Control Panel Overview

Image: Close-up of the digital control panel and remote, showing buttons for mode selection (grind, cut, weld), sensitivity, shade adjustment, test, lock, and delay.
- MODE Button: Press to select between GRIND, CUT, and WELD modes.
- SENSITIVITY (SENSI.) Knob: Adjusts the sensitivity of the arc sensors to detect the welding arc. Turn to accommodate different lighting conditions.
- SHADE Adjustment (+/- Buttons): Use these buttons to increase or decrease the shade level (4/5-9/9-13).
- DELAY Knob: Adjusts the time the lens remains dark after the welding arc stops. This prevents eye strain from afterglow.
- TEST Button: Verifies the auto-darkening function.
- LOCK Button: Locks the current shade setting.
Welding Operation
- Select Mode: Choose the appropriate mode (WELD, GRIND, or CUT) using the MODE button. For welding, select WELD.
- Adjust Shade: Set the shade level according to your welding process and amperage. Start with a higher shade and reduce if visibility is poor. Refer to standard welding shade charts for guidance.
- Adjust Sensitivity: Set the sensitivity to ensure the helmet darkens reliably when the arc is struck. Higher sensitivity is needed for low amperage TIG welding.
- Adjust Delay: Set the delay time to prevent eye fatigue. A longer delay is often preferred for high amperage welding or when tack welding.
- Begin Welding: Once all settings are configured and tested, you can begin your welding task. The lens will automatically darken when the arc is struck and lighten when the arc stops, based on your delay setting.

Maintenance
- Cleaning:
- Clean the helmet shell with mild soap and water. Avoid harsh solvents.
- Clean the outer and inner protective lenses with a soft, clean cloth and a specialized lens cleaning solution. Do not use abrasive materials or paper towels, as they can scratch the lens.
- Regularly check the auto-darkening filter (ADF) for dust or debris and clean gently if necessary.
- Lens Replacement:
- Replace scratched or damaged outer and inner protective lenses immediately to maintain optical clarity and protection.
- Refer to the helmet's design for specific instructions on how to remove and install replacement lenses. Typically, outer lenses clip into place, and inner lenses slide into a frame.
- Battery Care:
- Ensure the solar panel is clean and unobstructed to maximize charging efficiency.
- Charge the internal rechargeable battery regularly via the USB-C port, especially if the helmet is stored for extended periods or used in low-light conditions.
- Storage: Store the helmet in a dry, clean environment away from direct sunlight and extreme temperatures.
