my friend it appears you are on a steep learning curve about gas pressures and laser operations, I admire you for taking on the effort. Best of luck and thanks for the updates
You are correct most shop air systems are inadequate in volume and pressure however you numbers quoted seem way too high for a 1KW laser. 15hp (22KW) compressor that is specifically built for laser cutting - high pressure air end, several filters, dryer and tank should work.
Yes, on the low end. My plan is to upgrade my power source to 4 or 6kw over the next year or so. Who makes a high pressure air end that will produce 250psi? I havent seen any made for lasers?
@@turbocobra Ingersoll Rand 15t2x200-35 will cover you if you upgrade to 4 or 6 kW laser. Here is why www.dropbox.com/s/qbu9vxmmmd1ruzi/Nitrogen%20Pressure%20and%20volume%20for%20Laser%20cutting%20of%20stainless%20steel.jpg?dl=0
I know of lots shops that don’t do a lot of stainless and aluminum cutting that still uses 12 packs of nitrogen. Oxygen on the other hand, I ran a 5000 watt Trump for years on dewers alone, but that’s combustion cutting. Had some success using air on gauge metal, galvanized.
Suggestion: you need sub-micron filters on your incoming gas lines or you are going to spot your lens and have cutting problems. Liquid N2 vents 1% a day if you use it or not. You don't have enough power to cut 1/4" steel with N2. A 1KW laser would be dong well to cut 10 Gauge Mild Steel with N2.
Just a humble suggestion, instead of mentioning the prices and specifics every video. Tell the new viewers to check out the" link above" to view the original videos. This way you will have more viewers per video and you dont have to go through it every time. Either way i thoroughly enjoy the new laser vids.
its a good thought, but even in the original video, I didnt mention the price at the very beginning, and because of that people still asked. alot of people on youtube kind of skip through or watch parts of videos. oh well, hard to make a video that suits everyones needs lol
I hate to break it to you but unless you are running that thing every day you will lose more gas due to liquid boil off venting than cutting. It may be cheaper to run several gas cylinders in series to eliminate waste from venting. We use liquid argon for sintering metal 3d printed parts, we vent about half the dewar over two weeks unless we are running regularly.
Well your not breaking anything to me, definitely aware of the pros/cons of Dewars vs gas cylinders. Right now my volume isnt that high, but once i get the machine fully dialed in and ready for production cutting i don't think it will take long to get enough work to keep it running on a daily basis and I hope to use one of those Dewars per week.
FYI, you can get your nitrogen pressure just under the 250 psi relief valve. Just Increase the pressure on the mixing valve, turn the chrome cap on the mixing valve. It’s hard to see but there are little indicator lines under that silver cap
That's a good point and might be worth a try but I think he mentions in the video the dewar can't generate the flow rate at the pressure he was able to get. He might be able to bump up the delivery pressure but I don't think there is enough boil off from the dewar for the flow rates required by the machine.
Bill De La Vega Well all I can say is from our situation. We had the same exact issue. We had our gas guy adjust it and it was more consistent pressure than we could use. Had to back it down. We use 120 Psi at 12 CFM
@@readyross Again worth a try if he has not already done it. Gary mentions the pressure / flow rate for air is 250 PSI at 70 CFM. I imagine the flow / pressure for 100% Nitrogen would be less, but not like the Oxygen flow rate / pressure which is more like what you are using. In the comments Gary responded to me and said that the gas supplier is setting up the vaporizer system, so hopefully they have all the bases covered on the best way to supply what's needed to his machine.
Hello brother, I have the same fiber laser as you do without the tube and pipe cutter. I have some doubts and questions I would like to be cleared if thats okay with you? I am in a bit dire need of help. And if it's not too much, I would like to contact you personally and show you some videos of whats wrong with my machine
Thank you for your videos! Just got my DIY China Fiber laser. I bought your video coarse and found it very helpful. You mentioned in another video your were getting a high pressure air compressor, did you get it? How did it work out?
8:20 Really not familiar with psi In my shop i got a 380v 35hp compressor with filter, cooling, dehumidifier system... I am curious... Can it keep up with your machines?
what's the best way to contact you to get some work done I have a local guy with a plasma table that does most of my work but there is some things he he can't do he told me to find someone with a laser or a water jet

Thanks Tom! I am knee deep in the middle of it now lol. Its been fun to learn all about it
It would be awesome if you did an update video with all you've learned about gas setups since!
Hi friend
what happens if you run a normal gas nitrogen cilinder for tests?

Nice video Gary 👍!! You will be in good shape once your nitrogen vaporizer comes in.
yes sir, looking forward to getting that setup and going

Gocha, good info. So at 1% a day if you don't use any of it, it would be empty in 100 days. How do I get filters on the incoming gas?
Could you use Compressed N2 instead or is that not enough gas?
thanks for the videos, i found it really helpful
Really interesting projekt you got going there. I appreciate your videos and I was looking forward for some updates on how everything is working out.
Thanks Lars

Ever lay down on the machine table for a little accupuncture ??
lol no but thats a good idea
@@turbocobra little stress relief for those tough jobs 😀
Sir,our CNC LASER encounter nitrogen problem it can't supply sufficient although the nitrogen is new install the gauge can't hit 290

@@turbocobra What about a swing shift absorber like an oxygen concentrater in reverse
Air-conditioning suppliers have N gauges up to 600psi out, for 100-200 dollar range,

You may have had a high pressure Dewar? This is a low pressure one .
I was enquiring on the compressor required for air cutting and the power requirement on it came to 11kW.
Great video series ! Very helpful thanks for sharing!!
sure, you bet !
good information .. thanks
Parabéns, pelo vídeo!

In my shop i got a 380v 35hp compressor with filter, cooling, dehumidifier system...
I am curious...
Can it keep up with your machines?
yes
What’s the name of your Facebook group?
20 seconds in yeah im getting one
Does the liquid nitrogen tank have a pressure building valve like liquid oxygen tanks?
yes it does
Ramsey Customs - turbocobra we had some that worked great and some that just couldn’t keep up.
Cut the wire to the BEEP BEEP BEEP
Gary are you getting the vaporizer from your gas supplier? Are they setting up the system for you?
its though my gas company, and yes they are setting it up, same company i got the liquid nitrogen dewar through
@@turbocobra Good deal.
How thick it can cut mild steel?
the machine in the video is a 1000 watt and can cut 3/8" mild steel. 3000 watt can cut 3/4" mild steel
what's the best way to contact you to get some work done I have a local guy with a plasma table that does most of my work but there is some things he he can't do he told me to find someone with a laser or a water jet
you can call/text me at 972-754-4344. email me your files at gary@ramseycustoms.com
Exposed fiber laser? You wearing laser glasses?
How much price
Menit 0:55 Gas nya bisa Compressed Air, N2, 02
O2
Would think a guy with a machine shop could make a plug to stick in that nitrogen tank so it doesn't leak off. lol
lol it would explode! it continues to build pressure no matter what
Ramsey Customs - turbocobra minor detail. Lol You just need to cool the tank a couple of hundred degrees so it stops evaporating. 😎
What type of motors this machine is using?
FUJI AC Servo
