How long do your laser tubes and power supplies live?
Mine lives end surprisingly early.
CO2 laser cutters
1600x1000mm 130W, chiller cl-5500
500x300mm 60W, inside water chiller
Room temperature never goes below 16C.
Humidity: very low.
Maximum power in Lightburn: 75%.
First laser tube, nd950 60W - lived 9 months, ~1500h
It’s power supply MYJG-60W Zye - lived just10 months.
Second tube nd950 60W - died after 8 months, ~1500h of work. After this time I called help and found out that power supply, while having 75% power in Lightburn, gave 120% mA to the tube and it got fried slowly.
Power supply MYJG-150W Zye, blue - died after 18 months.
Tube RECI W6 130-150W - 19 months, ~3600h.
Also fried by too much mA - my fault this time. Didn’t read manual for the new power supply :’(
Anyway I started to think if it is common to buy a laser cutter in which the power supply is not calibrated right and gives a little bit too much mA so that it fries sooner and so you buy new tube/power supply more often from your supplier.
What are your tubes/power units lives?
