4. Setup
4.1 Headgear Assembly and Adjustment
Proper adjustment of the headgear is crucial for comfort and safety. The headgear features adjustable straps and spacers to ensure a secure fit and optimal viewing distance.
- Attach Headgear: Fit the studs of the headgear into the lateral adjustment boxes on the helmet.
- Adjust Horizontal Distance: The headgear has three adjustment slots. Place the spacers in the corresponding holes to adjust the horizontal distance between your eyes and the viewing window. This controls the space between your face and the helmet.
- For the left position, place the spacer on the second post.
- For the middle position, place the spacer on the third post.
- For the right position, place the spacer on the fourth post.
- Seating Spacer: Snap the seating spacer directly onto the top of the welding helmet.
- Mounting Locating Spacer: Attach the mounting locating spacer and nut on the outside of the weld helmet.
- Head Circumference: Use the comfortable head adjustment knob at the back of the headgear to tighten or loosen the fit around your head.
- Angle Adjustment: Adjust the forward tilt of the helmet using the angle adjustment mechanism to achieve a comfortable and effective viewing angle.

5. Operating Instructions
5.1 Power On/Off and Test Function
The helmet features fully automatic power on/off. Before welding, always perform a test of the auto-darkening function.
- The helmet automatically powers on when exposed to light and off when stored in darkness.
- Locate the "TEST" button inside the helmet. Press it to verify the auto-darkening function. The lens should momentarily darken and then return to the light state.
- A low battery indicator light is located near the test button. If it illuminates, replace the battery.
5.2 Mode Selection and Adjustments
The helmet offers various modes and adjustable settings to suit different welding and cutting applications.
- Shade Adjustment: Use the SHADE dial to select the appropriate shade level (DIN 5-9 or DIN 9-13) for your welding process. The light state is DIN 4.
- Mode Selector: Switch between GRIND, CUT, and WELD modes using the dedicated selector.
- GRIND Mode: For grinding operations (Shade DIN 4).
- CUT Mode: For cutting operations (Shade DIN 5-9).
- WELD Mode: For welding operations (Shade DIN 9-13).
- Sensitivity Control: Adjust the SENSITIVITY dial from MIN to MAX to accommodate different lighting conditions and ensure proper arc detection. Higher sensitivity is for weak arcs (e.g., 20A), lower sensitivity for strong arcs (e.g., 200A).
- Delay Control: Adjust the DELAY dial from FAST to SLOW. This controls the time it takes for the lens to switch back to the clear state after welding, preventing eye fatigue from residual glow.

6.2 Battery Replacement
The helmet is powered by a solar cell and a replaceable CR2450 lithium battery. When the low battery indicator illuminates, replace the battery.
- Locate the battery compartment, typically on the inside of the auto-darkening filter.
- Carefully open the compartment and remove the old CR2450 battery.
- Insert a new CR2450 battery, ensuring correct polarity.
- Close the battery compartment securely.
- Perform the test function to confirm the new battery is working.
