Reasonable working current of laser tube 130W

A lot of friends who use laser cutting machine get high deduct for order and raise laser current at will. Take the 130W laser tube for example, the current will be more than 40 Ma long.
It
So what is the reasonable working current of the 130W laser tube? Generally speaking, we recommend that no more than 25mA working current. If the current is controlled below 20mA, the service life of the laser tube will be greatly prolonged.
It
What is worth noting is that arbitrary increase of current will double down the service life of the laser tube.
