mA meter on 40w laser

Post by JosephPed »

I have a analog dial type mA meter on my 40w laser. It reads 25mA at max power, is this correct? I just read that the 40w laser should not be run at over 15mA?

25mA is not correct for 40W laser. The current should not be more than 20mA, 16mA is good. You can control the current by reducing power like 70% during working.
If you always use big current to work, the lifespan of laser tube will be short. Hopefully this information will be helpful for you.
