Prima Domino 16ga SS

Prima Domino 16ga SS

Prima Domino 16ga SS

I have a Prima Domino Laser cutter that was just purchased a year ago (used) to cut mild steel tubes with no problem. Now trying to cut .0625 (16ga) SS with not so great success, my issue is its creating a ton of dross on the bottom of the cut.
When I reference documents from Trumpf for SS the parameters seem totally different.  Could anyone advise? Thanks.

Nozzle - 2.0mm Single Nozzle

Here are my cutting parameters.  
Feed (80in/min)
Power (3500W)
Freq. (0)
Duty (0)
Gas (11Bar)
Stand Off (.04mm)

Power (2800W)
Freq. (190Hz)
Duty (60%)
Gas (2bar)
Stand Off (.150mm)
Focus (-.040in)

RE: Prima Domino 16ga SS

Your cutting speed seem very low; that might be the problem.  Try like 240"/min (you should be able to cut even faster with that power).
Your gas pressure might be a little high as well; try like 7 bar.
Finally, if that doesn't help, play with the focus: hard burr, go lower.  If it's small burr, go higher.

RE: Prima Domino 16ga SS

i run a domino too,i think you should try about -.09 focus 10-11 bar n2  the speed is quite normal i think.i am from sweden anyway

RE: Prima Domino 16ga SS

I agree with Foostrap, your feed rate seems extremely low for your power setting. The 2500 watt trumpf 1030 i run cuts 16 ga ss clean at 275 in/min and 10 bar, -2.3 mm focal point, 1 mm standoff. You should be able to get at least 325 - 350 in/min with your 3500 watts.

Also, why are your frequency and duty cycle 0 in your cutting parameters? They should be max or close to it for most materials, no?

RE: Prima Domino 16ga SS

Thank you all for your input. The duty and frequency were set by already loaded parameters so we took took these numbers and ran with them. Just now are we actually getting around to fine tuning.  I have since played with the feed rate to 300 and getting excellent results.  Ill update as I fine tune it more.
