I have two working lasers with almost brand new(under 500-1000 hours) tubes

LaserLife cutting only LCW-280 900x1200 bed with 300W Yongly tube(two CO2 tubes in a metal casing with combiner inside....

If anybody is chasing GSI(JkLaser) SLC140BP 140W tube I have two for sale.

One is dead and needs a regas and replacing an electrode.
Another still outputs about 120W-125W(last tested 2.5 years...

Hi guys,

Does anybody have anything to say about Yongli tubes?

I am considering their DLT-280 or DLT -300 tubes which is just two separate glass tubes combined design inside a metal case. It...

They have 30W one https://www.htpow.com/high-power-30000mw-blue-laser-pointer-laser-flashlight-sale-online-p-1084.html
With that much power it needs cooling, I cannot see how it can be cooled...

Here you go mate https://www.engraversjournal.com/article.php/2564/Images/Fig12Big.jpg
Shown as a yellow pin on the image behind autofocus. It should be black plastic so seemed to be replaced with...

I believe you :-) I have only tried to warn about this problem the OP just in case he has not thought about it in advance.

My 280W laser had an option to come with a tracing camera but I did not...

I guess that your laser is slow and very low power and you are not cutting anything thicker than 3mm so all smoke is getting sucked out before it can start building inside.
Try to do this with 100W...

Why do you think you can trust Speedy 400 more than GWeike lasers?
Sure they are built better but they cost a lot and break too.
From my experience my GCC Spirit GX breaks more often than my...

If you are planing to cut wood your camera lens will need a lot of regular cleaning. Just think of it comparing to a lens for the laser itself. Even with an air support and high pressure air ...

I have a laser with two tubes. I do not think you will find combining mirror on ebay. It is quite expensive. All it does is it allows one beam to pass thought it and the other to reflect from it....

I do not know much about a Camfive 1080K laser but it's not the only question if it can do 3d laser engraving or not.
The most important where are you going to get right grey scale images for it....

Are you serious? I have been quoted many times aroud $6000 for 140W GSI tube. It sound unreal that 400W can be sold for £6,000
If that's real I want a laser with 400W GSI tube :-)

BTW, I cannot...

If you need a perfect straight cut on such a thick material lasers are wrong tools for it. Even if you go with 4" lenses you still won't get straight cut. That's a nature of laser cutting. As an...

I do not know much about CW5000/5200 but I have got one(DWT-8PSA model) from Water Cooler with Water Tank | DERYUN PRECISE INDUSTRIES CO., LTD. | Product Information

It cools down two 140W tubes...

I do not have this exact model but I have GCC LaserPro Spirit GX laser. In order to get it working under 64Bit windows I had to upgrade my laser firmware. It was a USB driver related issue and new...

As suggested by others I would check beam alignment plus check that focal distance is equal all over your laser table. If your table is tilted that's when you get problems similar to what you are...

what kind of wood was it and what speed was used?

It seems it is cutting faster than my 280W laser unless it was softwood.
I use 480mm/m for 18mm thick MDF however 19mm pine is cut a few times...

my guess it is either your optic dirty(lens, mirrors) or you have dirt stuck to an output coupler of the tube itself.

Have you in any way moved the tube or even slightly changed its position?

When you say it is splitting, do you mean you can see two cuts next to each other(like a ghosting effect) ?

If you have...

Unless it is related to plywood only it is not entirely true. 280W in two GSI tubes is more than enough to cut through 18mm thick MDF.
Actually it is quite fast about 400mm/m at 90% of power. Not...

I can compare US(II-VI Infrared) vs Chinese(Bill laser) optics but keep in mind that I am getting US ones through the factory and the local distributor so there should be some extra in their cost for...

If it looks clean you can try to put the tube back.
I had the same problem but in my case I was the one responsible for dirt sticking to output coupler. I have two tubes laser I I had to cover one...

You can ask your supplier(in your case G.Weike) to provide you a shipping quote to your door. Suppliers from China usually can find a reliable agent in your country who will organise everything for...

Nothing wrong. I have a laser with two tubes. They are cooled from one chiller with same water. The laser comes with one inlet and one outlet from/to the chiller. However the tubes are not connected...

I do not know if SI model is different from GX but if it is the same in order to get it working you may need to update firmware of your laser.
I have spent a lot of time to get my Spirit GX...

I can cut through 18mm plain MDF on a 280W laser only. It uses 2 x 140W GSI DC tubes. I have never tried 18mm MR MDF but 15mm thick MR MDF does not seem to be a problem for the 280W laser.
The...

Hi Walt,

I have two machines with air supplied through the nozzle so it is pretty common to supply air straight to where the cut is. I have never had any problems with it and I cut a lot of MDF up...

I believe it has nothing to do with your lens or air assist. It seems you have this problem because you use cutting table with big solid areas made of metal. The beam needs some room under material...

Not a single laser techs in the whole Australia? :-(

Hi guys,

I am looking for an experienced tech in laser beam alignment preferably in Melbourne.
I have one new laser running two 140W GSI DC tubes and I cannot align the beam all over its...
