On the third laser with the screws at both ends you forgot to say don't drop the screws on your workshop floor. You'll spend more time looking for it than it takes to make the connection. 🤣 Thank you for making this video. Great information and a lot of details.
Great video! You're exactly right about putting plenty of silicon around the high voltage connection. If not, even if you don't get arcing you can still have corona that will give you problems.
Thank you Marco. Again with a nice video. You give a calm and splendid explanation. I think you have mutch experience on lasermachines. In the future you receive a lot of thumps up when more people will find you here on YT. Thumps Up!
Many thanks for explaining the details of installing the laser tube. At first I was very worried.. but now I feel much more comfortable. Quick question though.... is there a need for silicone jel on the last type of tube?
Marco, Thank you for doing this video. I'm working on the wiring of my laser build. This was very helpful in wiring the amp meter. Keep up the great work with the videos.
It is a special high voltage cable capable to carry 5kv without arcing. Do not use a regular electrical wire or you will get trouble. You can shop the cable from our website Lightobject
Where can I get the tubing? I have the second example one and used a suppplied cerammic block but have noticed some "browning" and would like to redo it with your method but wnat to make sure I use the correct tubing.
only very few DIYers have the technical equipment to solder high-voltage connections properly. Therefore, it is better to make the connection as shown in the video.
Do it a different way, get yourself a box of cable end ferrules of different sizes (the little round metal sleeves you crimp on the end of a stranded wire). Find a ferrule size that fits on the pole (or is close to it), if it is slightly too big you can just make it to size with some pliers so it becomes a friction fit on the laser tube positive pole. Solder the high voltage wire to the outside of the ferrule (do this away from the tube) while making sure the (now friction fit sized) inside of the ferrule is not clogged up by the solder. If done correctly you should now have a high voltage cable that you can connect to the laser tube without the need for a zip-tie and is still super securely attached (with better contact too) to the tube. Add silicone and a silicone tube as normal to prevent arcing and job done.
You have the picture to show? We found a pin-type connector that seems good for this use. I will post a new video for a new approach: pin and soldering.

Last time I checked how to do this - someone was using RV gasket maker.. but this! Using silicone tube ! oh man so much more elegant. So brilliant!

It is better to use silicone gel to shield not only the HV, but reduce oxidation.

Let me know what else do you want to learn and I will try to come up a video. I was very busy recently so I didn't post any new "How to..."😅
Thank you. Just applied this technique to my 130w laser. And it worked.
Great to know it helped!
Great video! very informative, what size wire is the positive wire to the tube, I need to extend the positive wire from the power supply.

Very helpful. thank you for explaining this thoroughly :)
What tool are you using at 9:51? What is the purpose of this tool? Is it some kind of crimper?
It is a cable tide. You can get it from Amazon for roughly $25
Where can I get the tubing? I have the second example one and used a suppplied cerammic block but have noticed some "browning" and would like to redo it with your method but wnat to make sure I use the correct tubing.
You can just trim a small piece from your water chiller tubing. It should made of silicon. Or , shop it from our store : www.lightobject.com
Hello i have the second laser tube and it just made electric arc do you know if i can repair it ?
What kind of silicon tubing for the positive side wire are you using?
The type you used on water chiller
@@LightObject thank you. The positive wire appears to only have a little wire and two protective sleeves, one harder and the red?
Thank you for this video.
Good video thanks where are you located. ?
We are in Sacramento, California
See Lightobject.com
Many thanks for sharing
i've seen some people use conductive pastes and glues as well to secure the bare wires to the terminals.
Another great video!!
Thanks!
Is there a reason why you didn't solder the positive cable connection? Wouldn't it be much safer to solder it?
Heat cause expansion and may cause gas leaking. Someone may have luck but some don't eo why take chances?!

why not use circle connectors when attaching to the laser tube is bare wire better? thank you

Great vidio
Excellent thank you 😊
is the meter for dc or ac ?
DC 30mA or 50mA depends on your tube size. Usually a 30mA is good for most
So thanks
