The laser power supplies are important accessories to keep CO₂ laser tubes working properly. Laser tubes with inappropriate power supplies may not be able to function ideally. To ensure that our users have good product experiences, we provide some suggestions on how to choose power supplies for different models of the laser tubes, shown below.

Considering the instability of external power supplies, protection on the high-voltage end, length of high-voltage cables and other factors that may affect the power supplies of laser tubes, we suggest users of 1600F7, 1700H7 and 1800W7 laser tubes use 150W stabilized voltage supplies or 180W power supplies.

In order to reserve space for upgrading 1400T7 or 1600S7 to 1600F7, 1700H7 or 1800W7 in advance, and avoid changing the laser power supplies after the upgrade, users of 1400T7 and 1600S7 laser tubes may choose 150W power supplies. Such power supplies with higher power will not affect the lifetime of the laser tubes as long as the working current of the laser tubes does not exceed 30mA.
