OMTech Pronto 35 100W CO2 Laser Engraver Cutter Instruction Manual

1. Safety Information

Operating a CO2 laser engraver requires strict adherence to safety protocols to prevent injury and equipment damage. This machine is a Class 2 laser product with 0.827 mW output power.

• Eye Protection: Always wear appropriate laser safety glasses when the laser is in operation. Never look directly into the laser beam.
• Ventilation: Ensure proper ventilation to remove smoke, fumes, and debris generated during engraving and cutting. The machine includes a powerful air pump and 318 cfm turbo exhaust fan.
• Fire Safety: Keep a fire extinguisher nearby. Do not leave the machine unattended during operation, especially when working with flammable materials. The flame-retardant PC board and window enhance safety.
• Material Compatibility: Only use materials approved for CO2 laser processing. Avoid materials that produce toxic fumes or can ignite easily.
• Water Chiller: The water chiller is essential for cooling the laser tube. Ensure it is properly connected and filled with distilled water before operation.
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.
• Electrical Safety: Ensure the machine is properly grounded and connected to a suitable power supply. Avoid operating in wet conditions.
• Overheating & Low-Pressure Alarms: The machine is equipped with advanced sensors that monitor air pressure and temperature, pausing operation if needed and triggering alarms for overheating (above 131°F) or low pressure.

2. Setup Guide

Proper setup is crucial for optimal performance and safety. Please note that the laser engraver and water chiller may arrive in separate packages.

2.1 Unpacking and Placement

• Carefully unpack all components. Retain packaging for potential future transport.
• Place the laser engraver on a stable, level surface capable of supporting its weight. Ensure adequate space around the machine for ventilation and access.

2.2 Water Chiller Connection

• Connect the water chiller to the laser tube according to the chiller's specific instructions. Use distilled water only.
• Ensure water circulates properly before powering on the laser tube.

2.3 Exhaust System Setup

• Connect the exhaust fan to the machine and vent it to the outside environment. Ensure the exhaust hose is free of kinks and obstructions.

2.4 Power Connection

• Connect the machine to a grounded power outlet. Verify voltage requirements match your local supply.

2.5 Software Installation

• Install the necessary software (LightBurn, RDWorks, CorelLaser) on your computer. Follow the software-specific installation guides.
• Connect your computer to the laser engraver via USB or Ethernet.
