Powersupply load loss using PPI ???

Hello to everyone,
i got a problem with PPI setting.
My co2 powersupply simply dryout during cutting.
If i cut a square every line from start is thinner and thinner. ( Power reduction )
Got anybody same problems ?
Maybe quick capacitor discharge ?
I don`t understant it ...
Thanks for help
