5.2 Battery Installation/Check
The helmet is powered by a solar cell and a replaceable CR2450 lithium battery. The battery is typically pre-installed.
- Ensure the battery is correctly inserted with the positive (+) side facing up.
- The solar panel assists in charging and extending battery life. Ensure the solar panel is not obstructed.
5.3 Protective Film Removal
Before first use, remove any protective films from both the inner and outer surfaces of the auto-darkening filter and the clear protective lenses.
6. Operating Instructions
The ARCCAPTAIN HSH-G999 helmet offers multiple modes and adjustable settings for various welding and cutting applications.
6.1 Mode Selection
Use the external controls to select the appropriate mode:
- Weld Mode (DIN 9-13): For ARC, TIG, and MIG welding. Adjust the shade knob to the desired darkness.
- Cut Mode (DIN 5-9): For plasma cutting and similar applications requiring lighter shades.
- Grind Mode (DIN 4): The filter remains in its light state (DIN 4) for grinding operations, providing eye protection without darkening.

6.2 Shade Adjustment
Rotate the external shade knob to select the appropriate shade level (DIN 9-13 for welding, DIN 5-9 for cutting). Refer to welding safety charts for recommended shade levels based on amperage and process.
6.3 Sensitivity Adjustment
Adjust the sensitivity knob to control how easily the filter reacts to the welding arc. Higher sensitivity is suitable for low-amperage TIG welding or when the arc is partially obstructed. Lower sensitivity helps prevent false triggering from ambient light.
6.4 Delay Adjustment
The delay control determines how long the filter remains dark after the welding arc ceases. A short delay is suitable for tack welding, while a longer delay is recommended for high-amperage welding to protect against afterglow.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding helmet.
7.1 Cleaning
- Helmet Shell: Clean the helmet shell with a mild soap and water solution. Avoid harsh chemicals or solvents.
- Protective Lenses: Wipe the outer and inner protective lenses with a soft, clean cloth. For stubborn dirt, use a lens cleaning solution designed for plastics.
- Auto-Darkening Filter: Gently wipe the surface of the auto-darkening filter with a soft, lint-free cloth. Do not immerse in water or use abrasive cleaners.
- Arc Sensors: Keep the 4 arc sensors on the front of the helmet clean and unobstructed for proper function.
7.2 Replacing Protective Lenses
Replace outer and inner protective lenses when they become scratched, pitted, or too dirty to clean effectively. Refer to the helmet's design for specific lens removal and installation procedures, typically involving clips or a frame.
7.3 Battery Replacement
When the battery indicator signals low power or the auto-darkening function becomes unreliable, replace the CR2450 lithium battery. The battery compartment is usually accessible on the auto-darkening filter cartridge. Ensure correct polarity when inserting the new battery.
8. Troubleshooting
If you encounter issues with your welding helmet, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lens does not darken | Low battery; Obstructed arc sensors; Incorrect mode/settings; Damaged filter. | Replace battery; Clean sensors; Check mode (not Grind) and shade settings; Contact support if filter is damaged. |
| Inconsistent darkening | Low battery; Dirty/obstructed sensors; Sensitivity too low; Ambient light interference. | Replace battery; Clean sensors; Increase sensitivity; Reduce ambient light or adjust sensitivity. |
| Poor visibility | Dirty/scratched protective lenses; Dirty auto-darkening filter. | Clean or replace protective lenses; Gently clean auto-darkening filter. |
| Helmet feels uncomfortable/loose | Headgear not properly adjusted. | Re-adjust headgear straps and ratchet knob for a secure and comfortable fit. |
If the problem persists after attempting these solutions, please contact ARCCAPTAIN customer support.
