For cutting I have -3.5 focal and 18 pressure i think. I come back with more. Give me feedback and i'll try to help....

Last time we cut new ones for the two tables. One table is 24 feet long so you can imagine how long it take to cut that. Trumpf's machine are cool. Try to ear people'opinions before. From now the less expensive and fastest is the zipgun. Still nobody eared about brass, suppose it does not stick?

Does someone have a special machine to clean the slats on the table or you just do it with the zipgun? Those machine are very expensive. Does it worth the price? Did you eared about brass slats?

On our machine we had to add a feature which allow us to be able to do that. We have Ermaksan and it work good. For my experience it worth it. But can't tell for your machine, may be it come with it when you bought it. Or maybe like laserninja said you have to change your thickness as simple as...

Since how long you got your laser? because you have the old version of precitec head which were very bad at my experience with them. I am very surprise he didn't offer you to upgrade the head for the new version of precitec. They did an amazing job with the new one. And with the bluetooth on it...

double nozzle is for mild steel.....use 1.5......2.....or 2,5 normal one (simple). your are lucky to go 20 hours without dammage.

Change your focal lens. With a 2000watts we reach perfect cut 7 ga ss 201LN at 70 inch per minute. This sunday i cut 27 sheets 20 feet long at 170 inch per minute using nitrogene. We just change the focal lens after 820 hours of cut. Normally the speed should be around 138 and 154. Slowly our...

Well thanks for the answer Merill101. Yes talking about etching. I'll try O2 and the power you say. I guess you are using a CO2 laser. I am not familiar with the duty but I will start with that. I will give feedback on it.

Hi i recently did some marking on half inch stainless steel and it work fine. Now they think to give me some marking to do on mild steel. I have a 4kw fiberlaser and the lowest power i can go is 400 watts. Is that possible to do it and what gas will be best nitrogen or oxygen? Is there kind of...

try speed up and more gas like 14 bar.

use oxygene around .07 bar. Is that a fiberlaser and how many watts do you have?

We have an Ermaksan 2kw fiber. We are using the new generation of precitec head witch is procutter.They have the bluetooth going with it. You can know exactly the temperature, the pressure, the wavelenght etc in real time inside the head. This is the kind of tool whitch is helping you keep the...

Go back to your original parameters if they were working before and clean your focal lens again. What size of nozzle are you using?

You have to be more specific about the thickness and what you were cutting.If you were cutting steel with n2, it was sure very thin steel and a focal +4 is very big. To cut steel you need o2 and not a lot of pressure gaz. With ss you should use a focal negative with a lot more pressure of n2...

I go for 1.5 nozzle.

I agree with you. From what I see we will cut thick pieces and often very long (20 feet). I don't known if it is normal but the guys who sell that machine use a lot of pressure to cut. They push very hard. They use an average of 15 to 22 bar for ss 12 gage to .250 inch. They told me and I cote...

Well thanks for the answer. Yes we had the valve stuck. With hot water we fix it but still working on it. The company who rent may change it. But from what I understand it is possible that the purity may change a bit. For the generator it seem to be realist that the system can be pay back in...

We have a 2000 liters tank. Twice in a short time we completely empty it. So we had to switch to the emergency bottle by the time they came to refill. In the same time the quality of the piece we cut were so so. Would like to known if emptying the tank can produce some humidity or bad quality...

First you need a buble nozzle; #1 or #1.2 depends of the result .250 mild steel use oxygene, less expensive; .6 bar Piercing have to be pulse Speed; 74 inch\min If you have dross under it it because of your protective lens dirty ...believe me it goes fast dirty if you don't cut tru...

I just started to do etching so I'll give you what work not too bad now. I'm not finished to experiment but this is what I am now. Power: 200 Nozzle stand off: .1700 Feedrate: 35in/min (huge difference with lasercutpaul, and I tried that speed but there was...
