    Question Laser power supply MYJG50W, I have burned TWO in one week... No idea why

    Hello guys!

    Im using classic "blue china laser cutter",

    last week my power supply dead because of burnt isolation on ceramic transformator:

    okay, **** happens I thought, and replaced burnt one with a brand new from the box...

    AFTER 6 hours it has gone without ANY visible trace of burning or any other defects.
    Green power LED is On, but it gives no energy to laser tube at all.


    So I have the last one MYJG50W installed, it works for now, but I am not sure if it will live for a long time.

    Found this video about conductive water, and leakage of current because of this

    Im using just a tap water for freeze with a bid of chloride to kill algaes. Can this cause an issue because of higher conductivity of "chlored" water?
    Yep, I got a slight discharge touching water in freezer.

    Also, during a cut I can clearly hear electric bzzzt sound from power supply unit, is it OK? It seems this sound was present always.

    If someone had such experience, please share it with us.

    My first MY JG-50W power supply on a 50 W CO2 laser failed without burning, and it costs 10% of the entire machine cost!!!
