3. Setup and Installation

3.1 Unboxing and Components

Carefully unpack all components from the shipping crate. Verify that all items listed below are present and undamaged.

3.2 Water Cooling System Setup

The CO2 laser tube requires a continuous flow of cooling water to operate correctly and prevent overheating. Follow these steps to set up the water cooling system:

1. Connect the water circulation pump to one end of the water tube.
2. Place the water pump into a bucket filled with clean water.
3. Connect the other end of the water tube to the water inlet of the laser machine.
4. Ensure the tube is securely fastened to prevent leaks.

3.3 Air Assist and Exhaust System Setup

Proper air assist and exhaust are crucial for clean cuts, preventing flare-ups, and removing harmful fumes.

1. Connect the air pump's outlet to the machine's air inlet tube.
2. Connect one end of the exhaust pipe to the air inlet of the exhaust fan.
3. Connect the other end of the exhaust pipe from the fan's discharge port to the machine's smoke discharge port.
4. Ensure all exhaust pipes are securely fixed with clamps to prevent detachment and ensure efficient fume extraction.

3.4 Electrical and USB Connections

Connect the machine to the power supply and your computer for control.

1. Connect the main power cable to the machine's power input and then to a grounded 220V AC outlet.
2. If applicable, connect the exhaust fan's power separately as its power consumption can be high.
3. After installing the necessary software (e.g., RDWorks V8) on your computer, connect one end of the USB cable to your computer's USB port and the other end to the machine's USB input port.
