  • Is my laser power supply really broken, or is my tube bad?  Watch this instructional video to determine if the Chinese CO2 laser power supply is truly bad.  Includes several individual indicators that the supply no longer works, or works properly.  A bad laser tube is shown here, not a bad power supply--see this video.

    What do these power supply specifications mean to me?


    Protection: with well-grounded enclosure, output circuit of power supply can be open for short time (but arc between positive pole and enclosure should be avoided).  This spec. translates into the following actionable items:  1. When installing the laser power supply, ground the power supply to the enclosure's metal (sandpaper if necessary) to make sure the ground wire from the power supply goes to the laser enclosure, and further, that the laser enclosure is earth ground.  2. Immediately power off if arcing is heard and/or seen (the red wire to the laser can degrade over time, or be installed improperly, so connect properly).  See enclosure arcing here on youtube.  See one method for proper wire connections here on youtube.  This means that you need to listen for arcing because the high voltage wires degrade with use (my 150 watt RECI wire began internaly arcing (inside the insulation) near the tube after about 25 hours of use, so I cut it back and have not had a problem since that time. 


    35KV maximum voltage. This is the absolute maximum power of the power supply according to this spec--though I never saw it when measuring the high voltage.  Now, the way the power supply works, is that it has a "strike" voltage to start the lasing then quickly drops to a steady voltage to maintain the lasing.  If this value is too low for your laser then the laser will not start to lase.

    Conversely, a higher rated power supply will do the job-see example here on youtube. However, if you are going to use a higher power supply, then drop the current down as much as possible while measuring the laser output power. In other words, do not run the laser tube with a higher output power than its rating--make a 60 watt run at 60 watts, not 70 watts or else it will die early.


     Input voltage: AC 220V+30 or AC 110V+20 (to be specified when placing order).  This means that you should put in the correct input AC voltage.  If 220V AC is wrong then you can convert to 110V AC using this instructable.  Or, if you find that your laser is putting out only half its rated power then you know it is wired for 220V AC as this person discovered.
