This is my first time posting on here, hopefully someone can help. I have a '90 Mazak TX-48 1500 watt laser. I've been cutting various
cold rolled steel thicknesses with good results and even .062 aluminum. I'm not having any luck with .125 aluminum with this cutting
condition;

Any help would be greatly appreciated. Thank you, Ron

I run a 89 mazak laser path that is also a 1500 watt. We cut .125" aluminum quite a bit with no problems. I would start with at least 1300 watts but run it contiuous wave (100% duty) with the feed at around 30-35 ipm. Other than that I use a standard 1.5mm nozzle with at least 130 psi. Nitrogen assist gas is prefered but oxygen seems to be good enough for me. I also use a standard focus which may not be the most optimum set up but this gets the job done for me as well. If I remember correctly 5000 or 6000 series aluminum is all we run too, so I would check to make sure the grade of material you are running is ok to laser cut. Hope this helps.
 
Thank you again fab3, the numbers that you provided worked great!
