When I received my 150 watt the supplier sent a suggested values for cutting and engraving.
Prior to this laser I was using a 100 watt with lasercut, but what i noticed is that they are suggesting running at 100% power
and varying the speed. there is only a few items that they took the power down to 60%
With my other laser i used various power settings , speed etc
My question is is it better for the tube to be set at 100% power(life expectancy)
