We have a 2012 Shenhui 1280 with Reci V4 100W.
I hardly ever need to fix it and my wife runs it. It doesn't run full time but must have lots of hours on it so far, will see if there is a menu to bring it up. Amazed the tube has lasted this long.
She has noticed that the cutting performance has dropped off so that something she might cut at 20mm/s maybe needs 16mm/s.
The ammeter is showing only 22mA and was 26mA originally. I have checked all the connections and they are good.
I changed the max power on the controller from 90 to 95% and it now runs just over 24mA and I will hear about the related performance.
Question is whether I get the spare tube out that has been stored since 2012. This was the original tube that came in the machine, I swapped them after about a month to check something and then put it in the cupboard. So it did work.
Is gas loss (which this presumably is due to the current drop, unless the PSU is going off) equal for a glass tube in use or in storage all other things being equal? Or is it related to use?
I improved the earths on the machine when we got it, but don't really want the downtime or potential explosion if the tube fails suddenly. Is it more likely to just gradually lose power?
