CO2 Laser

By refilling I mean when CO₂ in Laser is in consumption (wear off). This happen to machine for engraving after some thousand hours of works. If I can refill again by my self not to send again to the manufacturer.

Hello again bashkimi

You could probably refill the gas yourself, but you would need to flush out the old gas first, and know the following:

1. Gas mixture is probably not pure CO_2, so you would need the exact mixture of gases from the Manufacturer.
2. Gas Pressure is vitally important.
3. You would require access to a vacuum pump, to ensure no old gas or air remains.
4. Electrodes, Output voltage, Insulation and wiring etc will need to be checked.
   
5. The Laser unit will need to be re-calibrated.
6. You would need to check the weight of the laser unit, as it was filled to Manufacturer's Specification, to ensure you complied with all above.

Now unless you have the correct Data from the Makers, plus access to Laboratory equipment, you can see it is not regarded as advisable to refill the unit yourself.

There have been cases of Lasers exploding, or giving extreme output for a short time, then the electrodes fuse, after being incorrectly filled.

Summary: Your Laser unit is a precision device, and may be easily suddenly damaged, with hazard for nearby staff if incorrectly filled.

My recommendation is thus to use the Services of a local Laboratory, or Instrument Repairs Specialists, or send to the Makers, and ask them to do the re-fill and re-calibration for you.

I do realize the above advice is probably not what you want to hear.

Kind Regards....
