Key performance points of a carbon dioxide laser tube
The use of sealed-off CO2 laser tubes is mostly for laser cutting and marking. So what are the indicators that affect the usage effect?

Key parameters and precautions for Zener diodes!
The stabilization voltage is the operating voltage of a Zener diode in the reverse breakdown region, which is the voltage across the diode. This value varies slightly with the operating current and temperature. Even for the same type of Zener diode, the stabilization voltage value has a certain degree of dispersion. For example, the stabilization voltage of a 2CW14 silicon Zener diode is 6~7.5V.

Power Supply Repair Basics
Before repair, check if the power supply housing is properly grounded.
Power supply repair methods
High-voltage ignition, high-voltage wire connector too close to the iron shell.
Pulsed laser power supply
The pulsed laser power supply is specifically designed for pulsed Nd:YAG lasers. It uses a switching power supply and is controlled by a microcontroller, making it a true CNC power supply.
Continuous laser power supply
The power supply uses a constant-frequency, variable-width method to achieve high-precision constant current output. The output current ripple is small, and the stability is high. The ignition part adopts a three-stage current continuation method of series high-voltage package arcing, LC sub-high voltage relay, and low-voltage constant current continuation arc current. Coupled with an ignition monitoring circuit, it achieves automatic ignition, with a first-time ignition success rate of over 99%.
