Measuring power of CO2 Laser. Checking power of 50W Chinese Laser Cutter

Here I have taken a Mahoney Laser Power Probe and made some measurements on the actual output power of a 50W chinese ebay laser cutter.
The scene of the dial moving was a re-shoot and only goes up to 35W because I released the button a bit short. In careful measurements I do get 36W as my peak output power.
Prefer to read? Then I have article written about measurements at: makestuffnow.com.au/power-meas...

Thanks for the video. I tested my 50W Chinese tube with 2 different power supplies and got the same results as you; 36Watts. Just thought you would like to know. :)

0:58 Can't you just make a program that would cut a line at 1mm/s for 38mm, at the percentage in question?

Hi,
I have the same laser as yours. I'm looking for VENDOR settings, do you have a copy ? Thanks in advance.

It was interesting to see what the REAL power output was. What would you like to do with more power?

[@makestuffnow]

Cut thicker and cut faster. Some operations really benefit from faster speeds to reduce burning.

what is the price of the wattage probe?

[@Cknoble87]

Where can you buy one? Link?

So, if I buy 50W machine is literally a 35W...

[@makestuffnow]

It literally is a 45W tube, a few of the chinese tube sellers are beginning to label them honestly.
After about a year the tube will get weak to about 35W. If you buy a 'new' machine they may ship you one with an old tube in it.
