Built-In Rechargeable Lithium Battery

The 974nm 70W Portable Laser Igniter features a built-in 3S high-rate lithium-ion battery system, designed to provide portable operation without requiring an external power source during use.

Battery Features

• Integrated 3S lithium-ion battery configuration

• 1300mAh rated capacity per cell

• DC 5V/2A charging input

• USB-C charging interface

• Battery level indication

• Automatic charging cutoff

• Integrated battery management protection

Charging Instructions

1. Connect the device to a compatible 5V/2A charging source.

2. The red charging indicator illuminates while charging.

3. The charging indicator turns off when charging is complete.

4. Disconnect the charger after charging and before operation.

New devices may arrive with approximately 60–70% battery charge due to shipping and storage practices.

For consistent operation, fully charge the battery before first use.

Important: Use a compatible, high-quality charging adapter. Operation directly from an external power bank while charging is not recommended.

Power Controls & Battery Indicator

The device features a power control button positioned above the charging port.

According to the supplied operating instructions:

• Double Press: Turn ON the main device power. The battery indicator illuminates.

• Single Press: Turn OFF the device power.

The battery indicator may display fewer bars when the battery is partially charged.

Safety Reminder: Powering on the device should only be performed in a controlled laser safety environment. Never assume that the absence of visible infrared light means that the laser is inactive.

Coaxial Optical System & Adjustable Focus Lens

The device incorporates an integrated coaxial optical assembly with a detachable, adjustable focusing lens.

The lens assembly provides optical focus adjustment for compatible technical applications and equipment evaluation.

Optical System Features

• 974nm near-infrared optical source

• Built-in refractive coaxial configuration

• Visible red aiming beam

• Detachable focusing lens assembly

• Adjustable focusing mechanism

• Compact optical housing

The lens assembly includes a mechanical extension limit, identified by a visible sealing ring.

Important: Do not extend the focusing assembly beyond its mechanical limit or attempt to force the mechanism.

Optical adjustment and alignment should be carried out only by trained operators using suitable beam-control equipment and protective measures.

Dual Cooling System & Temperature Protection

The portable infrared laser system incorporates two internal cooling fans rated at 1.5W each.

These fans assist with heat dissipation during operation.

The unit also features an integrated thermal sensor designed to monitor internal operating temperature.

Thermal Protection Features

• Dual internal cooling fans

• Integrated thermal monitoring

• Automatic pump shutdown at approximately 45°C

• Temperature-based protective control

When the temperature reaches the specified threshold, the laser pump automatically shuts down to help reduce the risk of overheating.

The thermal protection system does not replace appropriate duty-cycle management or laser safety procedures.

Compact Aluminum Alloy Construction

The device is housed in a durable aluminum alloy enclosure with a sandblasted anodized surface finish.

Its compact construction makes it suitable for specialized portable optical equipment applications.

Housing Features

• Aluminum alloy enclosure

• Sandblasted anodized finish

• Integrated ventilation openings

• Compact dimensions: approximately 42 × 42 × 148 mm

• Integrated rechargeable power system

• Detachable optical lens assembly

Minor dimensional variations may occur between production batches.

Package Includes

• 1 × 974nm 70W Portable Infrared Laser Igniter

• 1 × Adjustable Focusing Lens Assembly

• 1 × Charging Accessory

Note: The rechargeable lithium-ion battery is built into the device and is not supplied as a separate removable battery.

Maintenance & Storage

To maintain the equipment in good condition:

• Inspect the optical outlet for contamination or damage before operation.

• Keep the front optical surface clean and free from excessive dust or residue.

• Use appropriate optical cleaning products and materials when necessary.

• Avoid touching optical surfaces directly.

• Do not force the focusing mechanism beyond its mechanical limit.

• Keep the device away from excessive moisture and extreme temperatures.

• Store the laser in a secure, dry environment when not in use.

• Recharge the battery periodically during extended storage.

• Avoid impact, unauthorized disassembly, or internal modifications.

For optical cleaning or maintenance, ensure the device is powered off and cannot emit laser radiation.

Important Laser Safety Information

WARNING – HIGH-POWER INVISIBLE INFRARED LASER RADIATION

This product operates at 974nm and emits near-infrared laser radiation that is invisible to the human eye.

Direct or reflected exposure can cause permanent eye injury, serious burns, fire, or property damage.

This equipment is intended only for qualified adult operators in appropriately controlled technical environments.

Safety Precautions

• Never aim laser radiation toward people, animals, vehicles, aircraft, or occupied areas.

• Never look directly into the optical aperture.

• Never rely on the visible red aiming beam to judge the presence or location of invisible infrared radiation.

• Always use certified laser safety eyewear specifically rated for 974nm and the device's verified optical output characteristics.

• Prevent unintended reflections from mirrors, glass, polished metal, and other reflective materials.

• Operate only within a properly controlled laser safety area.

• Keep unauthorized persons and children away from the equipment.

• Never leave the equipment powered on and unattended.

• Do not disassemble, modify, or bypass the protective systems.

• Keep combustible materials away from unintended beam exposure.

• Follow applicable laser safety regulations and standards.
