CO2 Laser Tube Common Working Problems

Weak output laser power

1. Check if any scratches or dirt on laser tube output lens and the laser tube put on laser tube support at right point (Marked as"suggested support point"on SPT laser tube).

2. Check the output current of laser machine, service voltage, cooling water temperature, cleanness and rate of water flow.

3. Check the cleanness of focus lens and the reflectors on your laser machine, check whether the lens and reflective mirrors get hot or the laser beam is not well aligned.

High voltage electric discharge ignition

1. Check if any sundries around the high voltage electricity joint or the laser tube is too close to metal part of laser machine;

2. Too humid indoor environment will also cause electric conduction phenomena. Please pay attention to phenomenon of condensation water in laser tube when using water chiller in summer days.

3. Check if any contact defective or open circuit in laser power internal high-voltage connections.

Laser tube broken or the laser tube ends fallen off

1. Cooling water temperature must be 15 to 25 degrees. The cooling water can be frozen in cold area to cause laser tube broken from inside, so don’t leave any water within the laser tube when temperature is under 0 degree.

2. The tube must run under water protection device is on. (To test the tube lights or not with water supplied or not)

3. Check the silicon water pipe is folded or pressed by something.

4. Check if any bubbles in the laser tube.

5. Check whether the cooling water flow rate is normal and the water is circled from low to high.

If conditions 1-5 are normal, it is laser tube quality problem.

Laser tube breakdown caused by wrong operations of 1~5 conditions is not covered by warranty policy.
