That was neat. First time I have seen someone go in-depth and explain about a laser tube. Clear and easy to understand. Thank you.
yes you are correct ,I got my k40 last week and the tube is clearly marked (peek power 37 watts,Normal power 35 watts)and the life can be extended by keeping the power below 75%.
I've had my K40 for nearly 2 years and it still works as good as when I first got it. However, I never use more than 6-10 ma. I only use it for engraving and not cutting.
Thanks for the info, now I understand why these tubes are so expensive. I guess there are no semiconductor lasers yet that can handle 100W of power.
Good point on the fumes.
I was running a diode laser when I first started.
Was looking at building fume extraction system and this and that.
One day of running all day and I got sick, very sick, light headed and headache and tired. So close to going to hospital. That day I said no more and sought out a co2 for the main reason that it comes with the fume management and safety.
Haha. I brought my K40 second hand and have had it for 2 years or more. I'm a hobbyist but I went to the trouble of setting up proper external extraction.
I think I might be some way along the road of having a useless tube by now. Oh well. I've had fun with it!
The claim on getting cancer depends on what you are cutting. Venting outside with a fan (without a filter) is just as effective at extracting the fumes for 1/8 of the cost.
Yes ! and your kids outside playing, what happens to them !!!
All to save $ 🤬
Do you have any suggestions to troubleshoot a laser that just completely shutdown in the middle of a job. I was cutting birch wood and suddenly the machine just shuts down and wont start back up. I check my breaker it was fine and I cant find any fuses on the machine to see if any is blown.
So when you buy a power supply for the tube..
Should it be based in the peak or the recommended run watt?
I think that choosing a laser machine depends on what you have to do with it. Most of us are hobbyists and therefore will buy a 40W laser machine for 300 bucks, then upgrade it with some features like air assist, replacing bed.... minor ones.
The mean duration of a laser tube is way more than 6 months, because we use it not everyday and not for 8 hours a day...
It’s like buying a Porsche to drive it up and down our alley. Does it makes sense? Nope. So we buy a Fiat 500 and we’re happy.
Not really laser will not be dead because you use less often. Laser has CO2 inside and other gases with smaller molecules will get inside the glass tube, this makes your tube useless. It has no effect wether you use it or not.
I rememer testing the beam width of 2 lasers I have worked with. At 100% the beam is the widest, I hate that ! So I always run at 60 to 70% Works like a charm. APARANTLY it also helps with the problem described in this video. Lucky me o.o
Yesterday I engrave on glass using co2 laser machine and it broke my lens.
Please tell me the reason
active filter - where did you get yours??
too wordy for my short patience even at 1.25x. a tl;dr in the beginning would be a great asset to your channel.
Roger Hello, My 100watt yueming machine controller is not working properly. It stuck sometimes in between the running command , then we need to turn off and turnb ON the machine many times then starts working again for an hour.. then again occurs same issue.
Great vids mate
I just bought new laser machine and I want ask you sr. About the distance between the end of laser tube adge and the the mirror
i killied mine in a month brand new. had a bad ma meter and burned a bit of the mirror in the tube
Hi! Thanks for the advice. I have almost the exact laser cutter in my garage, which is quite cramped. I have a hell of a time tilting it and trying to get the last bit of water out of the end of the tube. Do you have any tips for fully emptying the laser tube after use? Appreciation beforehand.
Hi, I never empty my laser, for the winter I have a heated workshop.
Thank you, for watching,
Please subscribe and forward the video on to a friend, Australian Inventor Roger Clyde Webb ;-)
Do you still need an active charcoal filter if you set exhaust to through air out of the work-space, in open air?
Hi, see my new video.
*NEW for 2020* Buying a 100 Watt laser *WATCH* before you buy!!!
I have a question for you. I purchased a 300w co2 mixed laser cutter and when I got it the tube had water in the bottom. I found out that it was broken. They are sending another. Upon talking to The seller I asked where my rotary tool was, and she said you don't need one. Apparently my laser cutter doesn't engrave!! Hers my Question, what feature makes the laser cutter engrave? Thank you from David.
OH DEAR!! we are in trouble, lasers are a very complex machine,and in reality you need to be part scientist to operate them. The answer to your questions cannot be answered hear, I have a facility on my Patron pages to best help you.

Thank you for talking about the carcinogenic nature of the gasses produced by laser cutting and engraving. Most of the new diode laser systems are being sold without enclosures and thus no extraction. More education on the dangers of inhaling these gases is needed.
Well said!
How do you know when tube is dead??? My laser is working and the tube isn’t firing today. I’ve had it 14 months and it does everything perfectly fine but fire . Please help.
It stops working!
Thank you 🙏
You’re welcome 😊
Thanks Roger.
Interesting info about laser tubes. Do you know how led lasers compare. When I added an led laser to my cnc I exhausted the fumes outside.
Cheers
Peter
Hi Peter, I don't think the problem exists with such low led laser power. The led lasers were developed primarily for DVD burners and the like if my memory serves me right. This type of led laser normally has a lifespan of between 7,000 to 10,000 hours, that is one of the reasons why your hard drive can fail after 3 to 5 years I suspect.
I exhausted the fumes outside, send the problem downstream, ha, ha, ha. I'll be sending you a private mail for a chat if that's ok.
Hi Roger I think you meant CD/dvd drive. The Hard drives use electromagnetism to write and read to the platters.
Roger Webb
Look forward to having a chat. The laser I have is 1. 4 watt but some use led lasers rated at up to 15 watts assuming the specs are actually true. Don't think what comes out the exhaust hose is much worse than what comes out the chimney on a cold winters night.
Cheers
Peter
Rob Hampton dvdrw. (Read and write) are commonly referred to as DVD burners and while not entirely technically/correct we know what he means, as for diode lasers they still stink when cutting so maybe not so safe, especially if you try to work with the wrong material, cheers
I learned more than I did at school
My first laser in on the way, it has a 100w reci tube and a ruida controller. Could you give me a guideline on what my max safe power would be please? Would hate to blow the tube right of the bat. Cheers
Hi, you need to check on the RECI web page for your laser tube max settings
Roger Webb will do, many thanks.
I’ve had mine for almost 4 years. Seems to be fine. ??
Same here, knock on wood!
I apparently spoke too soon. Just finished changing out the tube and the power supply. I think the power supply was ok. But had some work to do and didn’t want to chance it. It’s a 100watt system. I have to say. I think it’s working better now than it ever did. I’m cutting through 3/4” (20mm) hardwood at 90% and 5mm per second. With a 2” lens. Probably be even better with the 2.5” lens.
I just bought one and I thought it was a toy. I might die but lasers boomer.
Please how to remove water from laser tube...
What happens if you use a 150 watt tube with a 100 watt power supply?
Your 150w tube will run at about 100w max
Best laser tube....what??
1. Reci
2. Youngli
3. Efr..
Etc 🙏🏻❤️
RECI
thinking of byuing a laser cleaning machine 100watt from china...its costs less than half the price of a european..would i gamble?
JESUS CHRIST!!! IS THAT YOU???
@@rogerwebb9600 I am NOT! :P
so what is your opinion? should i gamble?
A lot of lasers on aliexpress labeled as RECI. Are those fake? They are 200usd more expensive thank normal tubes
Hi, RECI lasers are good so the price is more
@@rogerwebb9600 thank you for the message! Could you help me with 2 more answers? 80 VS 100 watts for cutting leather? And the head transmission with timing belt or the other system is better?
His is a Chinese unit also with an upgraded tube.
Most of these name brand lasers are made in China and all include the same electronics.
As soon as you join a group looking to buy a laser you get the individual trying to sell you the laser they import (from China) then tell you Chinese lasers are crap.
My 100/90W has a RECI tube. I fail to see the value in paying 12K for similar power
What do you think about gsi laser tubes?
Go RECI W2 laser tubes
@@rogerwebb9600 There is one machine with 150w gsi laser tubes (2pieces). I heard that they are made in England and thus realiable. Why do you choose reci? I am really confused. There are lots of machines!
Moreover, they can be refilled. At least this is the info I got!
what can you do with a 100 watt laser anyway? cant cut steel with it, even if it could it could not cut fast enough for real world production. What is everyone using these for? etching?
Engraving and cutting. Depends on what you limit the power to.
Laser: for cutting non conductive materials quickly.
Plasma: for cutting conductive materials like metal.
What brand is your laser machine?
Hi see video 503
th-cam.com/video/bhlInSx6a1k/w-d-xo.html
503 is on wiring a cnc?
Yes but just give it a look and I explain in this video
how to refill co2 laser tube in the home
Hi, you can’t, you will need to perchance a new reci tube
Thank you, for watching,
Please forward the video on to a friend, Australian Inventor Roger Clyde Webb ;-)
If you cut pvc it will put off fatal gas
YES IT WILL!!!
I am glad to see your video, plz share your email address to learn more about CO2 laser machines. have great day sir.

Informative video but your tag line about China !#$!@ is a bit unfair. The problem does not lie with China or their quality of manufacturing, as illustrated by the laser tube you recommend in the video as a good example. The problem is people wanting things, and not wanting to pay for them. The nationality of a product origin is no guarantee of quality, China just happens to have the structure to produce cheap tat at a lower price point that anyone else, and there is no shortage of people to lap it up. China is capable of, and indeed does, produce goods the equal of any other nation in the world. .
Yes I agree, and Thunder Laser is the “ONLY” chinese laser manufacturing quality company to trust!!!
