Excellent vacuum performance: The maximum vacuum reaches 5×10⁻¹ Pa, and the pressure rise rate is ≤ 0.8 Pa/h, ensuring a pure and stable environment inside the box. 

Efficient vacuum extraction system: It can quickly reduce the pressure from atmospheric pressure to 5 Pa within 30 minutes, thereby enhancing work efficiency. 

User-friendly operation design: Dual-sided layout, equipped with 6 long-arm glove ports and 2 large observation windows, conforms to ergonomics, allowing operators to perform dual-sided operations comfortably while standing. The observation windows are equipped with foot-operated automatic light-adjusting safety goggles, ensuring safety while facilitating operation. 

Integrated welding function: The box is equipped with a servo-driven welding gun positioning mechanism integrated within, enabling precise positioning and achieving high-quality welding. 

Intelligent control system: Utilizing PLC for automatic control, it enables the automation and interconnection of processes such as vacuum pumping, gas filling (argon gas), and pressure balance (with an accuracy of 0.1 kPa). The operation is simple and reliable.
