Welcome! In this video, we'll introduce the CO2 laser interface and its modes, including how to test the dot pattern. Here’s the factory default interface. It’s simple and easy to navigate. The laser has three main modes: Standard Dot Mode for general resurfacing, Swirl Mode for a spiral pattern, Swirl with Central Dot Mode for a combination of both. Let’s test the laser by firing test dots in each mode. Watch how the patterns appear. Check the results to ensure the patterns are clear. Adjust settings if necessary. That’s a quick overview of the CO2 laser machine and modes. For more details, refer to the manual or contact support.
