Mine comes on at full power for a brief period and lowers to a limited power which I use to center what I will be engraving and focusing the beam. When the job is over the laser stays on at a weak power for period, I have not timed it but I would guess 3 to 5 min. After the 1st power-up the laser does not com on until the job is started. I am still trying to get the exact setting for a picture I am trying to engrave, but have not be able to get it the way I want yet. The power-on beam at full power and will burn wood, the ending beam is weak and has not burned the wood. Hope this helps, but nothing is easy on these machines.
