## Safety in Quantum Air Laser equipment

Quantum range equipment is designed with a rigorous approach to operational safety, both in terms of construction and use in an industrial environment.

### Classification and wavelength
All three models — Q3A, Q5A and Q9A — operate at a wavelength of **1080 nm** (near infrared), typical of fiber lasers. This technology requires the use of **certified personal protective equipment (PPE)**: laser safety glasses appropriate to the wavelength and corresponding optical density, as well as flame-resistant work clothing.

### Sealed IP55 architecture
The entire range incorporates a **sealed IP55 architecture with forced-air cooling**. This design protects internal components against dust and splashing, reducing risks associated with electrical interference or contamination of the optical system in workshop environments.

### Installation without hydraulic complexity
By not requiring an external chiller or hydraulic installation, risks arising from water leaks in proximity to high-power electrical components are eliminated. Equipment is operational in **less than 5 minutes** without construction work or additional infrastructure.

### Standard single-phase power supply
All three models operate with **230 V AC single-phase (range 180–270 V)**, a standard power supply in any industrial installation or workshop, which simplifies electrical integration and reduces manipulation risks.

### Shielding gas
The use of **argon gas** as standard shielding gas contributes to obtaining clean and stable weld beads, minimizing splatter and metallic fumes. It is always recommended to work in spaces with **adequate ventilation** or specific smoke extraction systems for laser welding.

### Recommended best practices
- Always use PPE certified for 1080 nm lasers.
- Delimit the work area with laser area signage.
- Train the operator before first use.
- Check the condition of the head and welding gun before each shift.

Safety in laser welding depends on both the equipment and the workshop's operational protocol. QOVOLT recommends complying with current EN 60825 regulations on laser product safety.
