I have a general question about how to maximize the longevity of a laser tube. I have an 80 watt machine (Gweike LC6090) that I have just put a new EFR F2 tube into. The specs on that tube say it has an operating current of 28 mA. I generally try to run my machine at 21 mA maximum. Will operating at even lower power settings and cutting slower be easier on the tube / help make it last longer? Or is the situation more that there is a healthy power range which will preserve the tube if not exceeded?
Any help in better understanding this is appreciated. Thanks.
