Feiju Laser Safety Tips

Feiju Laser says you should follow the rules for laser safety. The table below shows important safety needs:

Note: Always use a safety box and water cooling when you test or use your CO2 laser tube. Keep your laser tube in a dry place with good air flow. Do not let the temperature change quickly. Check your tube every few months for dust, water, or cracks.

If you follow these steps, you lower risks and keep your workspace safe every time you check the CO2 laser tube.

Visual Check CO2 Laser Tube

A visual inspection helps you spot early signs of trouble before they become serious. When you check the CO2 laser tube, you need to look closely at the tube and its surroundings. This step keeps your laser running safely and efficiently.

Look for Arcing and Damage

Start by examining the tube for any signs of arcing. Arcing appears as burn marks, black spots, or melted areas near the electrodes or along the tube. These marks show that electricity has jumped where it should not. If you see any of these signs, stop using the laser right away. Arcing can damage the tube and create safety hazards.

• Check the ends of the tube for discoloration or pitting.
• Look for any melted or burned wires near the connections.
• Inspect the mounting brackets for signs of heat damage.

Tip: If you notice a burnt smell or see smoke, disconnect the power and call a professional. Do not try to fix arcing issues yourself.

Inspect Brightness and Color Change

When you power on the laser for a short test, observe the color and brightness of the discharge inside the tube. A healthy CO2 laser tube glows with a steady pink or purple light. If you see flickering, dim spots, or a change in color, the tube may have internal problems.

• A weak or uneven glow can mean the gas inside the tube is depleted.
• Bright flashes or sudden changes in color often signal electrical issues.
• Consistent brightness across the tube shows good health.

Note: Always use proper safety gear and a safety enclosure when you check CO2 laser tube during operation.

Check for Cracks or Leaks

Cracks and leaks are common issues that can lead to tube failure. You should inspect your CO2 laser tube every week to catch these problems early. Early detection helps you avoid bigger repairs and keeps your workspace safe.

• Look for small cracks along the glass surface.
• Check for water or coolant leaks around the tube and fittings.
• Watch for condensation or fogging, which can signal a slow leak.

Regular weekly inspections help you find visible damage, including cracks and leaks, before they cause major issues.

If you find any cracks or leaks, stop using the laser and contact Feiju Laser or a qualified technician. Never try to repair a cracked tube yourself.

Test Connections and Power Supply

Checking the connections and power supply is a key step when you check the CO2 laser tube. Good connections help your laser work safely and give you the best results. Follow these steps to make sure your system runs smoothly.

Verify Electrical Connections

You need to verify all electrical connections before you test the tube. This process helps you avoid short circuits and keeps your equipment safe. Use the following steps to check each connection:

1. Power off your laser machine.
2. Wait at least ten minutes so the power supply can drain.
3. Set up the connections using the correct wires, such as black and red wires with alligator clips.
4. Insert meter wires to measure the current in milliamps (mA).
5. Disconnect the thin wire from the laser tube.
6. Attach your wire to the laser using alligator clips.
7. Connect the new wire to the meter’s red wire and use an insulator for support.
8. Attach the thin wire from the power supply to the meter’s black wire.
9. Double-check all electrical connections and prepare to take readings.
10. Power on the laser and watch for sparks or arcing.

Tip: Always use insulated tools and keep your hands dry when you work with electrical parts.

Use Power Supply and Cooling Loop

A stable power supply and a working cooling loop keep your CO2 laser tube safe. Make sure the power supply matches the tube’s voltage and current needs. Use a water cooling loop to prevent the tube from overheating. Check the water flow and temperature before you start the laser. If the cooling system fails, turn off the machine right away.

• Use only clean, filtered water in the cooling loop.
• Check for leaks or blockages in the tubing.
• Monitor the temperature during operation.

Troubleshoot Non-Firing Tube

If your laser tube does not fire, you need to find the cause quickly. Start by checking the power supply and all connections. Look for loose wires or signs of damage. Test the power supply output with a meter. If the tube still does not fire, inspect the safety switches and interlocks. Sometimes, a faulty switch or a tripped interlock can stop the tube from working.

If you cannot find the problem, contact Feiju Laser for expert help. Never try to repair the power supply yourself.

By following these steps, you make sure your connections and power supply are safe and ready every time you check the CO2 laser tube.

Measure Output and Performance

You need to measure the output and performance to make sure your CO2 laser tube works as expected. This step helps you spot problems early and keep your laser cutting or engraving at its best.

Set Low Power and Measure Output

Start by setting your laser to a low power level. This keeps you safe and protects your equipment. Use a CO2 laser power meter to measure the output. The BLUETIMES YL-S-III High Quality 0-200W Desktop Water Cooling CO2 Laser Power Meter works well for this job. It has a broadband coating that gives you reliable readings at the 10.6 µm wavelength, which matches the CO2 laser tube. Place the meter in the path of the beam and record the power output. Compare the reading to the tube’s rated power. If the output is much lower than expected, you may need to check the CO2 laser tube for deeper issues.

Tip: Always measure output at low power first. This reduces risk and helps you catch problems before they get worse.

Monitor Temperature Increase

Keep an eye on the temperature of your CO2 laser tube during operation. Use a water recirculating device to cool the tube. Check the water flow and make sure the temperature stays steady. If the tube gets hot quickly or the water feels warm, the cooling system may not work properly. High temperatures can damage the tube and lower its lifespan. You should stop the test if you see a sudden rise in temperature.

• Use a thermometer to check water temperature.
• Make sure the cooling loop has no leaks or blockages.
• Replace the water regularly to keep the system clean.

Note: A stable temperature means your cooling system works well and your tube stays safe.

Spot Weak or Inconsistent Beam

Watch for signs that show weak or inconsistent beam output. These problems can affect your laser’s performance and signal that the tube needs attention. Common signs include:

• Noticeable drop in power
• Visible arcing inside the tube
• Output significantly lower than the tube’s rated power

If you see any of these signs, you should stop using the laser and inspect the tube. Sometimes, cleaning the optics or checking the connections can fix the issue. If the problem continues, contact a professional or Feiju Laser for support.

Regular checks help you catch weak output early and keep your workspace safe.

A careful approach to measuring output and performance helps you maintain your CO2 laser tube. You protect your investment and ensure your projects turn out well every time you check the CO2 laser tube.
