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

[anthan]

It would be awesome if you did an update video with all you've learned about gas setups since!

[brianwoll]

Nice video Gary 👍!! You will be in good shape once your nitrogen vaporizer comes in.

what happens if you run a normal gas nitrogen cilinder for tests?

[andup]

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.

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.

thanks for the videos, i found it really helpful

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.

[BillyHardcase]

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.

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.

Sir, our CNC LASER encounter nitrogen problem it can't supply sufficient although the nitrogen is new install the gauge can't hit 290

Ever lay down on the machine table for a little accupuncture ??

[designsquared]

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.

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?

[impactodelsurenterprise]

I was enquiring on the compressor required for air cutting and the power requirement on it came to 11kW.

[bijoybiswas]

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

[faballnorth]

Great video series ! Very helpful thanks for sharing!!

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

[JAMESHOPKINSIBXCNC]

Does the liquid nitrogen tank have a pressure building valve like liquid oxygen tanks?
