How much does the multimeter pull down the current? I notice the laser intensity fades when I have the meter in series downstream from the laser tube. This makes me think that the meter must have some resistance and that the current reading may not be entirely accurate. At full power my meter reads 23.6 mA. Should I assume that is accurate?
These laser power supplies are some of the most commonly used laser power supplies. In other words, most Chinese laser machine assemblers (they assemble the machines from purchased components) buy these parts and install them in their machines. These power supplies follow some common standards (such as the two layouts for the controls wiring). As a result of this standardized format, the controls makers (companies that design and sell controls, like Step Servo with their Leetro brand), are compatible with these power supplies. To say it another way, these power supplies can be easily connected to a variety of control modules and are not tied to any specific controller manufacturer.
Hi have just set up my new 60w chinese laser cutter and thr interface on it is in chinese and when i try the pulse button nothing happens and error message comes up in chinese. Ther does not seem to be any pwer going through the laser tube not sure what to do next any ideas.
How to use a CO2 laser power probe to measure laser output power to locate a bad mirror
There are four terminals FG, AC, AC, L(-)FG- EarthAC- PhaseAC-NeutralL(-) - Negative supply for laser
Hi everyoneThree years ago I began using a laser tube machine.The CO2 Laser tube worked perfectly well for three years.But recently I started having problems, even with the new one.So far I had no idea what might be the problem but, thanks to this article, now I know that the power supply can be the principal cause of the CO2 Laser Tube Problems.I also have a very important fact to share.Our laser machine includes a power booster,which doubles the current from 110V to 220V.But guess what? The cables were inverted inside the power booster box,and therefore, when we thought the machine received 220V, it really gets only 110V. But we solved the problem.Thank you all for your comments.They've really been helpful for me.Success with your projects. - faschessmaster
hi i've repaired many laser power supplies both output wires comes from HV transformer it seems from the picture that the other wire is one which is insulated by a tube wherever that one is connected you can solder other prob from there - kamlesh2303
