When your CO2 laser engraving cutting machine don’t have laser light, you need to check which if laser tube or laser power supply has problem. This articel to introduce how to test the laser power supply.
Step 1: Please install the laser tube to the laser machine, even the laser tube is damaged.
Step 2. Turn on the laser machine (turn on electricity ). laser power supply will show : L 0 as the above picture:
Step 3: Press “Pulse” on laser machine panel, to see what value on laser power supply? Here take Reci W2 laser tube as example,
|Laser power setting||Normal current value on power supply||Test result ?|
|Set your laser power 80%||Approximately 25ma||?|
