Thinking about upgrading your CO₂ laser tube from a 60W to a 90W—or beyond? Before you grab a higher-wattage tube and hit the power switch, there are critical components and compatibility checks you should consider to protect your machine, avoid headaches, and get the performance boost you're after.
Here’s a step-by-step checklist to help you plan a smart and safe upgrade.
Not all tubes are the same length or diameter—even within the same watt class. A 90W tube is generally longer than a 60W, and may not fit inside your machine’s existing housing without modification.
Your CO₂ tube’s rated wattage must be matched with the correct high-voltage power supply. Underpowered PSUs won’t run a stronger tube efficiently (or at all), and overpowering a lower-watt tube can destroy it.
⚠️ Mismatched PSUs are a leading cause of tube burnout.
Higher-wattage tubes generate more heat and require more robust cooling. If your current setup includes a CW-3000 (passive chiller), you may need to upgrade to an active chiller like a CW-5000 or CW-5200.
💡 All Rabbit Laser USA packages include a CW-5000 chiller for long-term reliability.
Even small changes in tube length or mirror position can throw off your beam path.
📏 Make sure your beam hits center on all mirrors before moving to the focal lens.
Your laser controller (e.g., RuiDa) may need updated max power limits in LightBurn or RDWorks.
Higher power often means faster cutting—but it also produces more smoke and debris.
🔧 Rabbit Laser USA’s DL-series includes larger air assist out of the box.
Your machine’s safety label should reflect the upgraded specs, especially in educational or shop environments.
Upgrading your CO₂ laser tube can unlock deeper cuts, faster production, and new project capabilities—but only when the rest of your system is ready to support the change.
Not sure what your machine is capable of? Contact Rabbit Laser USA for guidance—we’ll help you cross-reference your frame, PSU, cooling, and more before you make the leap.
Whether you're scaling up or starting fresh, Rabbit Laser USA is here with solid machines, lifetime support, and calibrated upgrades that work as hard as you do.
