I have that mA meter on order from Lightobject and I was wondering where to put it

How did you find the 100% power point for your laser? I've seen figures like 18mA for 40W tubes but I doubt that's universal.

I imagine I could probably go above 60% output on my tube and be safe, while engraving, because the power fluctuates and is not steady as when cutting.
I have looked at several spec sheets on 40W glass laser tubes and most all of them state that max current is around 18-22 mA. I am new to the laser game so if I am way off base, someone please straighten me out.
