CO2 Laser Headaches

My K40 Cheap Chinese CO2 laser arrived a couple weeks ago. 

After much eager anticipation, I had it in the lab, and running within 6 hours. 

I have the machine shop seed project to make with it, along with many other items.  My productivity was dramatically increased over sending stuff out and using the mill.

However...

The power supply went out of it with about 10 hours of use. 

I filed a claim with Ali Express and the Chinese seller made all sorts of accusations saying it is my fault it broke etc so he would not have to pay the warranty. 

Things degenerated down to where he was sending me insulting emails, nasty messages, and being quite rude.  He even told me I had absolutely no right to file for a warranty claim. 

I was thinking to myself "WOW" the arrogance of this guy.

So if you should choose to buy a CO2 laser do not buy from "Wonderful Power Machines" run by some guy who calls himself Jessie Fang.

I took it to a electronic specialist and he disassembled the power supply to discover that it was poorly made.  Not in the assembly, it was very nicely put together, but the parts used were poor quality and several parts were absent that should have been in the design.  It was even without insulation on the MOFSET transistor.

So after a rebuild of the power supply it is now happily turning out parts in the shop.  I even have it engraving parts numbers before cutting.  A step up.
