At the end of the life of the 30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200w co2 laser tube, the power of the30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200w co2 laser tube is reduced, the color of the 30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200wco2 laser tube is whitish, and the30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200w co2 laser tube cannot meet the needs of the customer. At this time, the co2 laser tube needs to be replaced, and the 30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200wco2 laser tube should pay attention to the following items when replacing:
1. Installation requirements
The positive electrode of the30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200w co2 laser tube is in a high voltage state (ignition voltage is 24 kv). Failure to follow instructions can have the following consequences: arcing; the inner tube can be pierced by electricity and can cause water leaks.
2. Operating conditions
Water-cooled: using purified water; 3 to 5 liters / minute; water temperature: 10 ° C - 40 ° C.
Working environment: temperature 2-40 ° C; humidity 10-60%.
Operating current: The test current is 30 mA. The maximum operating current is 30mA. The operating current must be kept below 28mA. If the current is kept below 26 mA, the lifetime can reach 10,000 hours. The ammeter must be connected to the negative pole of the30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200w co2 laser tube.
When working under excessive current for a long time, the negative electrode will appear brownish yellow and the life will be shortened rapidly.
To prevent dust from entering the insulation sheath, wrap it in a plastic film.
Engraving function: very good. When the operating current is 4 mA and the tube is in a pre-ionized state, the laser can be used for high frequency pulse engraving.
Do not use a tool such as a tampon to clean the outer surface of the output widow. Otherwise it will seriously affect the output power. The following are the specified methods for removing the contamination of the outer surface of the mirror:
1) Do not turn on the laser when the mirror is contaminated.
2) Blow the mirror surface to the side with a blower.
3) Spray pure alcohol on the mirror surface with a sprayer.
4) After the alcohol has completely evaporated, turn on the laser.
5) If the above method does not work, ask a professional to clean the mirror to the middle to the edge with a tampon and alcohol. The best solution is to prevent windows from being contaminated.
Note: Do not clean the mirror with acetone.
It is not allowed to move the screws on the front and rear ends of the laser tube, otherwise the output power will drop or even be scrapped.
When testing the laser spot, place the acrylic at 300mm from the output mirror.
The laser beam is invisible light. Wear protective glasses when debugging the laser. The positive electrode is in a high pressure state. Pay attention to the safety signs.
6. Storage and transportation requirements
Pour out the coolant during storage and transportation, and cover the output terminals with a dust-proof plastic bag. The storage environment is 2-40 ° C, and the required humidity is 10-60%. The laser is packaged in the original way.
Important: Use tape to bond the sponge to the30w 40w 50w 60w 70w 80w 90w 100w 120w 130w 150w 180w 200w co2 laser tube. to prevent it from sliding vertically during transport. The sponge on the side of the output mirror must exceed 70 mm, and the sponge on the side of the mirror must be 50 mm wide.
