Hi

I am the programmer and operator of an Amada PulsarA4-NT 2415 for a small architectural metals firm. I have received very little formal training, so my knowledge of laser fundamentals and grasp of conditions creation is limited to what I've picked up from a few short training sessions and my experience running the machine for a year. Information on laser cutting in general, let alone my specific machine, seems to be difficult to find (everything on google is sales information it seems), so I am hoping that I will be able to find some valuable info here on eng-tips.

The main issue that I am struggling with at the moment is refining my cutting conditions for 1/4" hot rolled steel to eliminate a couple of issues. Most importantly, I am getting a lot of molten splash during my pierce, and the pierce holes blow out to approx. 1/8-3/16". I am also having an issue with pitted corners, as well as spurs where the lead-in line meets the rest of the cut. I've attached some pictures as an example of the latest piece that I cut.

I have also attached pictures of my current cutting conditions. They are a bit of a mess from previous users, but the set of conditions I am currently working off of is row 4. The rest give me a worse cut. I've been trying to tinker with the pierce as well as fine data to eliminate these issues, to little avail. Any recommendations for adjustments would be much appreciated.

Thanks!
