We have a Bystronic laser that is causing us problems,
With have a vacum leak somewhere and unable to find.
Both Heat exchangers have beeen sent away and checked all glas ware has been removed and replaced, however under advise we brought in a hand held Hellium sniffer unit and pump Hellium into the system instead of nitrogen so to locates any leaks.
we did identify possible problem areas and fixed. However we are still losing pressure approx 12/14 m/bar per minute with the result being loss off power.
Has anyone else experienced this and how did they overcome the problem?
