I dont cut SS or Aluminum, but as far as CRS goes, if productivity is your main concern.i would recommend cutting with shopair instead of nitrogen or oxygen, it gives us a better cut than oxygen and sped up our productivity by close to 20-50% depending on our detail. it also gives us a far sharper cut, it leaves a small amount of dross on the bottem far more than oxygen and nitrogen.  but it comes right off with a bell wire attachment on an angle grinder.  If you have a good compressor capable of at least 150psi. and 22 CFM, and a good dryer It would deffinatly be the most productive way to go.  I work at a shop that has the same laser you just purchased and we only cut HRS for decorative home furnishings.  if your want cut conditions for shop air let me know (the cut conditions for HRS and CRS are identical with shop air), or cut conditions for oxygen HRS, wich will vary slightly from CRS.

last I heard, Amada still provides tech support for its machines.
If you need apps help for a current Amada machine, call Amada and ask for applications support.

Aluminum sucks to clean cut. As far as SS goes, 300 psi nitrogen assist and high power....nice clean finish on SS.

In a hundred years, it isn't going to matter anyway.

The Pulsar LC1212 was an advance over the older Amada machines, because it has cutting condition tables in the control. I expect that you can get Amada to send you cut tables for your control. You can then tweak them to your heart's content.
What power is your machine? Did it have cut tables in the control? Did you get the programming and operator manuals with it? If not, Amada still stocks them.
Oh- is it the 1212, or the 1212A2?
(I worked at Amada for a looong time, mostly in the laser group)

This is a 1212. I was looking for a tuned cut table for different material. We got user's manual and machine's manual. But nobody here have experience with a laser and the one who's trying to operate it .. bah .. you all know what i want to say.

If you haven't run a laser before, and nobody else in the company has either, then the company should send you to a class (or have one done there).
I haven't really looked for cutting knowhow on the web. It may be hard to find...

yep we had one .. but as i said .. nobody here haven't run a laser before .. We actuallly doing a good job but it's take a long set up time ..

You need cut condition for SS, Aluminum and CRS. What thickness? I like using shop air for aluminum and stainless steel up to 14 ga. Oxygen for CRS and HRS. State which thickness you need cut condition for.

Where are you guys located?

Yes,  where are you guys located at?

Is this a Pulsar 1500 Watts?  2000 Watts? 3000 Watts?

Is it an LC1212? LC2415?
Is it an Alpha, Alpha 2 (A2), Alpha 3 (A3).

I may have these conditions you need.  E-mail me.

We are located at Granby, Quebec, Canada.
This is a 2000W
LC1212 Alpha3

I would like to thank all of you and if someone need a Job .. let me know

hello i have some cut cond about this kind of laser

if you need help to adjust param

I have also pps of cutting result explanation

mail me back remi-1978@wanadoo.fr

Another question for you .. how could i cut a 1" flat bar. Cause i always get an alert and the machine stop if i go under 1.5"

You could make a fixture to hold the flat bar in place.  If memory serves me right, the dead-zone around the clamp area is 300 x 30 mm when using the sensor head, maybe you set and program the clamps to reposition to avoid the dead-zone around the clamps.

Good Luck

I fixed my problem. But there is annother one .. the older to maintian the sheet in place dosen't move  .. a fixture is the best way but a little too expensive for that job..

Expensive?
You have a shop, you "make" things there!
A "fixture" means maybe a sheet of 16 ga or so, that the piece to be cut can lay on top of.
A few bent tabs or such to restrain the strap, and cut windows in the 16 ga where you are actually cutting the strap so the  spraying metal can exit.

Sometimes we think of machining stuff, where you have big tool forces and such.

Laser cutting is easy there- essentialy no tool cutting forces, just (in case of Pulsar) making the workpiece follow the clamps in one axis.

Expensive .. I mean we only had to produce a few pieces .. so we didn't want to  spend time on this. I just wanted to know if i could do it, for the future.

Thanks to all of you, and keep this forum active it is so nice.

We have the same laser.
For a quick fixture

Take a piece of 11 ga steel or sst and cut to size needed for the base of the fixture. Cut an upper piece to act as a banking edge or pocket. Make both pieces with holes in same location and rivet together. Drill & tap a couple of 1/4 UNC holes for clamps.

Because you made it on the laser, you already know where zero is. Draw the parts you want to make in CAD on that position and program.

Off you go. Cheap and quick.
