Compatibility & Installation
The SPT C35 is intended for compatible CO2 laser machines designed to accommodate a 720mm long, 50mm diameter glass laser tube.
Before ordering, verify the physical dimensions of your existing tube, available mounting space, power supply compatibility, cooling connections, and operating current requirements. Similar wattage ratings do not always indicate interchangeable laser tubes.
Important Installation & Safety Information
CO2 laser tubes operate at dangerous high voltages and produce invisible laser radiation. Installation and electrical connections should be performed by qualified personnel following the manufacturer's safety procedures.
Maintain proper cooling water circulation during operation. Do not operate the tube without adequate cooling, and protect the cooling system from freezing.
Follow SPT's recommended operating current and cooling requirements to help prevent premature tube damage.
