What Can a 350W CO2 Laser Cut? When evaluating a 350W CO2 laser, most buyers focus on cutting thickness and speed. However, in real production environments, long-term consistency often matters more than peak power. This article explores what a 350W CO2 laser can cut, why two machines with the same power rating can perform differently, and how the quality of a CO2 laser tube influences cutting performance, reliability, and operating costs.
