I have all the piercing lead ins with no delay to minimize reflection. 2 sheets in with no problems yet.

www.noualaser.com/ this is the company, I bought it on Amazon.

Kerf is at .009” right now, might be smaller as I haven’t tuned it in yet. This was cutting 11ga at 1500 watts.

@@kwrigg Wow, that is small. That is about as thick as you can do with fine cut consumables on a Hypertherm, but a much smaller kerf.

Oxygen is definitely on the to do list. The cooling system is routed to the welding head per the supplied documentation with chilled water. I also know this to be true because I could feel the welding head getting cold when I was dialing in the chiller temp. Thanks for the tips!

English Translation: "Very good... How did you do to reduce the delay? I have a 1500w hand laser, but there is a 1.2 second delay between pressing the trigger and opening the laser... and sometimes there is a small variation in this time... +- 0.5sec I will cut 1.2mm stainless steel sheets. About compressed air pressure... below 100psi creates a lot of slag on the edge. Thanks. I'm thinking about using pure O2." On the Laser unit control screen, there is a setting for delay of cutting from flow of gas to start of laser. I didn't mess with it and just made sure my lead in was long enough. If you have variation in start time, it might be in the safety clamp not getting a good connection between your cut piece and gun. I'm running right around 100 psi but might be dropping under 100 psi while the laser is cutting so my next step is upping the psi. Im planing on using oxygen when i try cutting thick steel as I have read this will increase the thickness available to cut.

Thought of the reflection being an issue too but I make sure I’m not pausing on the pierce and have the machine moving instantly to keep the laser beam from reflecting back. Just make sure the lead in is long enough to let the laser get all the way through before you get to the profile lines.

Thanks!
