Common Faults and Solutions for CO₂Laser Tubes
⚡ CO₂ Laser Tubes are widely used in laser engraving and cutting machines. They often have similar faults during use. Here are the most common problems and simple solutions.
No Laser Output
🔍 Possible causes: The laser tube is aged or damaged. Loose wiring or poor connection. Incorrect power supply or high-voltage failure.
🛠️ Solutions: Check and tighten all cables. Test the power supply and high-voltage board. Replace the laser tube if it is completely faulty.
Weak Laser Power
🔍 Possible causes: The laser tube is near the end of its service life. Dirty lenses or mirrors. Unaligned light path.
🛠️ Solutions: Clean the optical components regularly. Readjust the light path. Replace the laser tube if power continues to drop.
Unstable Laser Output
⚠️ Possible causes:
Poor cooling or low water flow. Unstable working voltage. Air bubbles in the cooling water.
✅ Solutions:
Ensure normal water circulation and cooling. Use a stable power supply. Remove air bubbles in the water pipe.
Short Service Life
🔍 Possible causes: Frequent switching on and off. Poor water quality or overheating. Long-time overloading operation.
🛠️ Solutions: Avoid frequent startup and shutdown. Use clean cooling water and change it regularly. Do not work continuously at full power for too long.
🔧 Proper daily maintenance and timely troubleshooting can greatly extend the life of CO₂ laser tubes.
