60w power supply question

[JAV-1]

On my machine, in hopes of upgrading to a 60 w tube in the future. I am running a 60w power supply and a 40w tube. Currently, the power setting in the LaserCad software is at 45% in the Manufacturer Settings, 75% at the individual settings for the file. With that in mind, while cutting, I'm only getting to 15mA at the meter. I'm looking for help on the settings to get maximum performance and hours from my tube.
Also, when the time comes, where is a good power starting point for the 60w tube?

Hi. You should ask tube manufacturer how much current it needs, but most of 60w co2 laser runs on 22mA. See below, this is current ratings for standars co2 laser tube, not RECI !
