How to choose correct co2 glass laser tube for your machine

Most end customers have no idea about which laser tube is the right one for their laser cutting & engraving machines when they want to replace the old tube, even they have been using laser cutting & engraving laser machines.

There are more than thousands of laser cutting/engraving machine suppliers in the world, but there is no international standard to define a laser tube power. Even for same size laser tube, different suppliers could tell you different laser power. For example, L1200*D50mm 60w laser tube, actually most suppliers say it is 60w, and some suppliers say it is 65watt, 70watt, even 80watt. Thus it happens a lot some customers don’t get a correct laser tube, it can be size problem, or the new tube cannot cut as thick material as the old one.

We, SPT laser, as one of the professional co2 laser tube manufacturers in China, deeply know that the laser tube power is defined when the tube length and diameter are assured in production. E.g. the rated power of a L1200*D50mm laser tube must be 60w, no other possibilities. Thus the easist way for customers to tell the laser tube power is by tube length and diameter. You could just choose the tube according to the size of the old tube on laser machine if you have no interest into its real power when buying a new one. This saves you much time and trouble.
