If you have a small or desktop laser cutter or a low-power laser engraver,

But need to make thick material cutting or get faster cutting speed,

Then the best choice is to upgrade your laser cutting machine to higher power by yourself

 

 

 

 

 

 

 

 

 

 

 

To upgrade the laser machine to a higher power, the first laser parts you need to upgrade is the laser tube

 

 

 

 

Commonly different laser tube power has different length,

One can already give output higher laser power, following is the popular specification for co2 laser tube

 

 

 

 

Tube Model	Rated power	Peak power	Length of laser tube	Diameter of laser tube
C50	50w	70w	1000mm	50mm
C60	60W	80w	1200mm	50mm
C80	80w	110w	1600mm	60mm
C90	80w	100W	1250mm	80mm
CS100	95W	115w	1350mm	80mm
C100	100W	120W	1450mm	80mm
C130	130w	150W	1650mm	80mm
C150	150W	180w	1850mm	80mm

NOTE: Different manufacturer produces laser tube with low power of different peak and lengths

 

 

 

 

 

 

 

 

The second parts of the laser need to be updated is the power supply of the CO2 laser (PSU laser)

 

 

 

 

 

 

 

 

 

Higher power laser tube with higher temperature inside, need industrial water chiller with compressor for cooling

Commonly 80w laser tube or less, the CW3000 cooler without compressor will be fine. But if it improves to 100w, 130w, 150w laser tube,

Then chiller with compressor will be neccessary like CW5000 or CW5200 (for double laser machine cutting head)

 

 

 

 

 

 

 

 

 

 

 

If you would like to cut thicker materials such as acrylic or wood/mdf, you should check the focal length of your current focus lens

Commonly lenss that the material of 10mm thickness, 1.5 ", 2" and 2.5 "focal length lens will be suitable,

But for cuting10-20mm materials, then 2.5 ", 3" or 4 "focal length lens will be necessary.

 

 

 

 

 

 

 

 

 

When you upgrade the laser cutter to a higher power, these 2 sizes should be checked twice as shown below:

 

Size "A" is the distance between the laser tube exit window and the first mirror, it should be> = 5cm

Size "B" is the high voltage end of the laser tube, the distance between the laser tube to the machine body

In each directionMust be> = 10cm to avoid the risk of high voltage discharge

 

 

 

 

 

 

 

 

The other thing that should be considered for the update of the laser is the new length of the laser tube

TThe best option is to choose new laser tube shorter than the machine body,Which is it can be put inside and installed well

 

If the necessary laser tube is longer than the machine body, then the solution for you is

Extend machine body with extended coverAs a photo above to fix and protect the laser tube.
