How to Tell When a CO2 Laser Coding Machine Tube Is Bad?
The tube shows signs of arcing. This will result in all sorts of electrical interference noise which may cause the laser to pause/reset. A sure tell sign is if the job runs no problem with the lid open (motors move but no laser firing) but pauses/resets with the lid closed (laser firing).
The laser tube has very weak brightness or glows white instead of pink.
Even when aligned, it has a hard time cutting acrylic at 100% power at 15% speed. Acrylic is a very consistent material and if you can't cut it at these settings. If it cuts better in the left position than the right side, you are simply out of alignment and not a tube problem.
You test the laser with a laser power meter and it shows 50% of it's rated power or less.
The Co2 laser coding machine uses CO2 gas to fill the discharge tube as the medium for generating the laser.
When a high voltage is applied to the electrode, the discharge in the discharge tube can make the gas molecules release laser light. After the laser energy is amplified, the machine forms a laser beam for processing materials. Then the laser beam is changed by a computer-controlled vibrating mirror to realize automatic engraving of materials.
That is, the laser beam irradiates the surface of the material to instantly convert light energy into heat energy. This process makes the surface of wood materials melt or even vaporize instantly, thus carving to form marks.
