150W CO2 Laser burning wood
Wear safety glasses guys! in this case OD7 or higher and certified, no china crap!
unfocussed, at nearly 12mrad (lol) the spot is quite big
PWM duty cycle was 55% of 60% (almost full power, maybe 130..140W) at 60 the psu turns off since its going into overcurren protection. with both 3000W psus at the same time it works.
the water cooler is not even close to cool this thing down when running full steam. of the 3000W, 2850 or more are going into waste heat.
i probably should get rid of it before i hurt myself
