The standard glass DC tube has a service life of 1,000 hours, and the component is typically covered under the manufacturer's warranty for 1 year. Depending on how frequently a laser is in operation, this part will require replacement after 8 months – 1.5 years. In comparison, a metal or ceramic RF tube maintains its for 5 – 6 years. If there is a drop in performance, it can usually be refilled with the CO2 gas mixture. This can extend the service life of the part by another 4 years.
Laser systems in Trotec's Speedy series are equipped with 100% ceramic tubes developed with CeramiCore® technology.* With regards to warranty, Trotec offers standard 2-year warranty on the entire laser unit. With a TroCare Protection Plan, users can receive coverage for up to 10 years.
*Models in the Speedy series with a maximum power level exceeding 30 W.
A laser's belt lays a key role in moving a laser's gantry. Production-grade systems usually incorporate steel-reinforced belts, which are resistant to stretching. Plastic belts, on the other hand, are commonly found in low-end lasers. These belts need periodic lubrication to function properly, and they often require frequent replacement.
On the whole, production grade-belts require minimal maintenance. Trotec's InPack Technology™ keeps the belt and other components well protected from dust and debris, even under extensive usage.
Heat is produced when energy is building up inside of a laser tube, which can damage both the tube and machine if it is not released. At lower wattages (i.e., ≤ 120 W ), production-grade systems usually incorporate fans that are automatically activated when the laser turned on. Low-end laser tubes are typically cooled using a tank filled with a special coolant. Users must periodically replace the coolant, and frequently monitor its level.
CO2 lasers, regardless of grade, produce substantial amounts of heat at high wattages (i.e., ≥ 200 watts). In this case, most machines require a tank and coolant to maintain a safe tube temperature.
