3. Components Overview
The ARCCAPTAIN LY800J welding helmet includes the following main components:
- Welding Helmet Shell
- Auto-Darkening Filter (ADF) Lens Assembly
- Headgear with adjustable straps and comfort cushion
- Outer and Inner Protective Lenses (replacement set included)
- CR2450 Lithium Batteries (2 included, pre-installed or separate)
- Storage Bag
4. Setup
4.1 Headgear Adjustment
Proper adjustment of the headgear is crucial for comfort and safety. The headgear features multiple adjustment points:
- Head Circumference Adjustment: Use the knob at the back of the headgear to tighten or loosen the band around your head.
- Top Strap Adjustment: Adjust the top strap to position the helmet correctly on your head, ensuring the viewing area is at eye level.
- Distance Adjustment for Eye-to-Lens: Adjust the distance between your eyes and the ADF lens for optimal viewing and comfort.
- Angle Adjustment: Use the side buttons to adjust the angle of the helmet when it is in the raised position.
4.2 Battery Installation/Check
The helmet is powered by two CR2450 lithium batteries and solar panels. Ensure the batteries are correctly installed and have sufficient charge. The solar panels continuously charge the batteries during use, extending their lifespan.
4.3 Protective Film Removal
Before first use, remove any protective films from both the inner and outer surfaces of the ADF lens and the clear protective lenses.
5. Operating Instructions
5.1 Auto-Darkening Function
The helmet features an auto-darkening filter (ADF) with four arc sensors. The lens automatically switches from light to dark in 1/25000 seconds when an arc is detected, protecting your eyes from intense light. It returns to a light state when the welding arc ceases.
5.2 Shade Adjustment
The shade level can be adjusted using the external knob. Select the appropriate shade based on your welding process and current:
- Grind Mode: DIN 4 (Light State)
- Cut Mode: DIN 5-9
- Weld Mode: DIN 9-13
5.3 Sensitivity Adjustment
The sensitivity knob controls how easily the sensors detect the welding arc. Adjust it to prevent false triggering from ambient light or to ensure proper darkening in low-light conditions. Options include Minimum, Middle, and Maximum sensitivity.
5.4 Delay Adjustment
The delay control determines how long the lens remains dark after the welding arc stops. This prevents eye strain from afterglow. Adjust the delay from 0.1 to 0.8 seconds (Fast, Middle, Slow).
5.5 Wide Application
This helmet is suitable for various welding and cutting processes:
- Stick Welding
- MIG Welding
- TIG Welding
- Plasma Cutting
- Grinding
5.6 Optical Clarity and Viewing Area
The helmet features a 3.94" x 3.66" super large visible screen with 1/1/1/1 top optical clarity and true color technology, enhancing visibility and reducing eye strain.
6. Maintenance
6.1 Cleaning the Helmet
Clean the helmet shell with a mild soap and water solution. Avoid harsh chemicals or abrasive cleaners that could damage the material or finish.
6.2 Lens Cleaning and Replacement
Clean the ADF lens and protective lenses with a soft, lint-free cloth. Replace scratched or damaged protective lenses immediately to maintain clear vision and protection. The helmet comes with replacement outer and inner lenses.
6.3 Battery Replacement
If the low battery indicator appears or the auto-darkening function becomes unreliable, replace the CR2450 lithium batteries. Ensure correct polarity during installation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lens does not darken | Low battery; Sensors blocked; Incorrect sensitivity setting; Ambient light interference. | Replace batteries; Clean sensors; Adjust sensitivity; Shield from excessive ambient light. |
| Poor visibility | Dirty lenses; Scratched lenses; Incorrect shade setting. | Clean lenses; Replace protective lenses; Adjust shade to appropriate level. |
| Helmet feels uncomfortable | Improper headgear adjustment. | Re-adjust headgear straps and knobs for a secure and comfortable fit. |
