1. Introduction
Thank you for choosing the YESWELDER LYG-L600A Auto-Darkening Welding Helmet. This manual provides essential information for the safe and effective use, setup, operation, and maintenance of your welding helmet. Please read these instructions thoroughly before use and retain them for future reference.
2. Safety Information
Welding and cutting processes can be hazardous. Always follow safety precautions to prevent injury. This welding helmet is designed to protect your eyes and face from sparks, spatter, and harmful radiation under normal welding conditions. It is crucial to understand that this helmet alone does not provide complete protection against all hazards.
- Always wear appropriate safety glasses with side shields under the welding helmet.
- Ensure the helmet is properly adjusted and fits securely before starting any welding operation.
- Do not use this helmet for laser welding or overhead welding applications.
- Inspect the helmet and lens regularly for any damage. Replace damaged parts immediately.
- The helmet provides continuous UV/IR protection up to Shade DIN 16, even in the light state or if the auto-darkening function fails.
- This product complies with ANSI Z87.1, EN 379, CSA Z94.3, and EN ISO 16321 standards.

4. Setup
4.1 Headgear Adjustment
The headgear is designed for optimal comfort and fit. Adjust the following to ensure proper positioning:
- Tightness Knob: Rotate the knob at the back of the headgear to adjust the circumference for a snug fit.
- Top Strap: Adjust the top strap to position the helmet correctly on your head, ensuring the viewing area is at eye level.
- Angle Adjustment: Use the side knobs to set the desired angle of the helmet when in the down position.
- Distance Adjustment: Adjust the distance between the helmet and your face for optimal viewing and comfort.

4.2 Battery Installation/Replacement
The helmet is primarily solar-powered but uses a replaceable CR2450 lithium battery as a backup. A low battery indicator will illuminate when approximately 2-3 days of battery life remain.
- Locate the battery compartment on the auto-darkening filter (ADF) lens.
- Rotate the cover to open the compartment.
- Remove the old CR2450 battery (if replacing).
- Insert a new CR2450 lithium battery with the positive (+) side facing up.
- Close the cover by rotating it until it clicks into place.

5. Operating Instructions
5.1 Power On/Off
The helmet features automatic power on/off. It activates when exposed to light and deactivates after a period of inactivity to conserve battery life.
5.2 Test Button
Before each use, press the TEST button on the ADF lens to verify its proper functioning. The lens should momentarily darken and then return to its clear state. If it does not darken, check the battery or consult the troubleshooting section.
5.3 Shade, Sensitivity, and Delay Adjustments
The helmet offers adjustable settings to optimize performance for different welding tasks.
- Shade Control (DIN 4/9-13): Use the external knob to select the appropriate shade level (DIN 9-13) for your welding process. The helmet also has a light state of DIN 4 for grinding.
- Sensitivity Control: Adjust the sensitivity knob to control how easily the lens reacts to welding arc light. Higher sensitivity is suitable for low amperage TIG welding, while lower sensitivity helps prevent false triggering from ambient light.
- Delay Control: Adjust the delay knob to set the time the lens remains dark after the welding arc stops. A shorter delay (0.1s) is suitable for tack welding, while a longer delay (0.8s) is better for high amperage welding to protect against afterglow.

5.4 Grinding Mode
To activate grinding mode, set the shade control to DIN 4. In this mode, the auto-darkening function is deactivated, and the lens remains clear, providing protection against impacts while grinding. Always ensure the helmet is in the correct mode before starting any operation.

6. Maintenance
6.1 Cleaning the Helmet
- Clean the helmet shell with a mild soap and water solution. Avoid harsh solvents.
- Wipe the auto-darkening filter (ADF) lens and cover lenses with a soft, clean cloth. Do not use abrasive materials or cleaning solutions containing alcohol or ammonia, as these can damage the lens coatings.
- Regularly check and clean the sensors on the ADF lens to ensure proper function.
6.2 Replacing Cover Lenses
The helmet uses outer and inner cover lenses to protect the ADF lens from scratches and spatter. Replace these lenses when they become scratched, pitted, or too dirty to clean effectively.
- Carefully remove the retaining frame or clips holding the cover lens in place.
- Remove the old cover lens.
- Insert a new, clean cover lens, ensuring it is properly seated.
- Reattach the retaining frame or clips.
