Power Output: Metal RF tubes provide higher power output, making them more suitable for industrial and heavy-duty cutting and engraving applications.
Lifespan: Metal RF tubes have a significantly longer lifespan, resulting in reduced maintenance and replacement costs over time.
Stability and Reliability: Metal RF tubes offer better stability and beam quality throughout their lifespan, leading to consistent cutting and engraving results.
Price: Metal RF tubes are generally more expensive than CO2 glass tubes due to their higher power and longer lifespan.
CO2 Glass Tube:
1.Construction: CO2 glass tubes are made of glass and filled with a mixture of CO2, nitrogen, and helium gases. The electrodes are placed at either end of the glass tube.
2.Excitation Method: CO2 glass tubes are excited using a DC (direct current) voltage, which ionizes the gas mixture and produces the laser beam.
3.Wavelength: CO2 glass tubes emit a laser beam at a wavelength of 10,600 nm (infrared), which is ideal for cutting and engraving non-metallic materials like wood, acrylic, leather, and plastics.
4.Power Output: CO2 glass tubes are available in various power levels, typically ranging from 30 to 150 watts for laser cutting and engraving applications.
5.Lifespan: The average lifespan of a CO2 glass tube is around 3,000 to 6,000 hours of operation, depending on the tube’s quality and usage.
Metal RF Tube:
1.Construction: Metal RF tubes are constructed with a metal (usually ceramic) core and have metal electrodes. The gas mixture inside the tube is excited by radio frequency (RF) energy.
2.Excitation Method: Metal RF tubes use an RF power supply to excite the gas mixture, producing the laser beam.
3.Wavelength: Metal RF tubes emit a laser beam at the same wavelength of 10,600 nm (infrared) as CO2 glass tubes, making them suitable for cutting and engraving non-metallic materials.
4.Power Output: Metal RF tubes are capable of higher power outputs compared to CO2 glass tubes, ranging from 100 to 300 watts or even more.
5.Lifespan: Metal RF tubes have a longer lifespan compared to CO2 glass tubes and can operate for around 20,000 to 30,000 hours or more.
