As we all know ,electric power is different in different countries ,so it is as laser power .I think many friends know ,laser power is used for laser cutting machine .With the development of technology ,more and more friends choose Chinese laser cutting machine ,it is important to test and set Chinese CO2 laser power .This blog tell you how to do it base on 11 steps .
Step 1:Do Not Touch the Red Wire.
1. Power off laser machine
2. Wait ten minutes. this is the time for the power supply to drain power from its electrical capacitors.
3. Setup as shown in photos below. You will need to purchase and use two sets of wires. We recommend a black wire with aligator clips on each end and a red wire with aligator clips on each end. These wires should be available at radio wireless
A. See the power supply wire connection. Do not touch the red wire. It has extremely high voltage that is lethal.
B. See the thin wire. It is colored blue, or black, or green as shown.
Step 2:Insert Meter Wires to Measure Current (mA)
See the meter below as an example meter. Some meters are slightly different, so adjust instructions as needed. Set meter to read current at mA. Set meter to read DC current. Insert red cable of meter into meter connection for current (labeled mA, or micro A, or A).
Step 3:The Meter Reading Should Show the Proper Units (mA) and a Zero Value
Step 4:Disconnect Thin Wire (colored Blue or Black or Green) From the Laser.
Step 5: Connect Your Wire to the Laser (aligator Clip Is Useful on Return Wire).
Step 6:Connect Your New Wire to Meter Red Wire.
Use an Electrical Insulator, Like the Wood Block Shown, to Support the Wire at the Connection.
Step 7: See the Solid Electrical Connection.
See Its Location, in the Center of the Wood Insulator Plank.
Step 8:Connect the Thin Wire From the Power Supply (colored Blue/black/green) to the Black Wire of the Meter Using Your Wire (alligator Clips Are Useful).
Step 9: More Cable Connections Located in the Center of the Insulating Board
Step 10: Confirm Electrical Connections. Take Reading.
Check and confirm all connections and review these instructions. After you confirm that all connections have been completed properly, then power on the laser machine.
Using the touchpad, select Menu and set the laser power to 5% and the time to 3000 ms. Power on the the laser from the touchpad and read the meter after the number settles. To confirm that you have no problems, there will be no sparks or electrical arcing. If sparks or electrical arcing then stop all work, power off the machine.
If the meter provides a reading and no sparks or arcing, then proceed by setting the laser power to 100%.
The current measurement at maximum output power should be 28 mA for a long life setting for a standard Chinese CO2 glass laser tube. If the value is higher (such as more than 30 mA) then the internal gases will be consumed much more quickly during operation and the glass laser tube will need to be replaced more often.
Step 11: Adjusting the Potentiometer to Reduce Current
To adjust the current downward, consult your power supply manual. DO NOT open the laser power supply enclosure and insert your fingers. Using a grounding wire, ground everything when working on a power supply. I was shocked six hours after power off, by touching the underside of the circuit card inside the laser power supply. Always use a wire connected to ground to remove any lingering voltages stored in the capacitors inside the laser. In many cases, the enclosure does not need to be opened and the potentiometer can be adjusted.
Okay ,hope this steps can help you ,at the same time ,thank you for your reading .
