Precision Engraving:

• The YL H-Series CO2 Laser Tubes offer superior construction to produce stable laser beams for precise markings on a wide variety of materials.
• Cut through thick materials and engrave your designs faster, deeper, and clearer.
• The water outlet and inlet allow efficient flow of cooling water.
• Made out of borosilicate glass, copper, and aluminum alloy
• Equipped with threaded poles to attach a red laser guidance system (not included) that allows easy mirror alignment. No more taping your mirrors!
• Simple and easy-to-use grounding and power connections
• We recommend using the OMTech CW-5200 industrial chiller with distilled water to maximize the laser tube’s lifetime.

Extended Lifetime:

• 90W Borosilicate Glass CO2 Laser Tube with an estimated lifetime of up to 12,000 operation hours depending on power setting usage and water cooling performance
• PLEASE NOTE: Frequent use of high laser power settings will shorten the laser tube lifetime as follows:
• Low Power 10–40% = 11,000–12,000 Hours
• Moderate Power 40–70% = 8,000–10,000 Hours
• High Power 70–100% = 4,500–5,000 Hours

Advanced Features:

• EASY TO INSTALL: The preinstalled YL cathode and anode terminal connections with a full metal structure allow safer and faster replacement.
• SAFE AND SOUND: The inner tube for the engraving laser beam is surrounded by built-in water tubing and a hermetically sealed outer tube to keep it cool and high functioning. Ports at either end allow easy connection with your water pump or industrial water chiller, and a protective cap shields the high-voltage anode from any shorts or arcing.

Package Includes:

• 1 x H2 90W Laser Tube
• 1 x User Manual

Warranty:

• No need to worry! We offer a 9-month warranty on this laser tube.

Certifications:

• FDA Compliant
• CE Certification
• ISO9001 Quality Certification 

Summary:

No matter how well maintained, laser tubes—like light bulbs—are temporary parts that eventually burn out. Replace your old tube with OMTech's heavy-duty YL H2 laser tube. Made of tough borosilicate glass, this durable 90W CO2 laser tube leaves competitors behind. Designed for medium-sized CO2 laser engraving machines, it is 4'2" (1250 mm) long and 2.3" (60 mm) in diameter. It installs quickly and easily: just wrap your power supply's connecting wires around the anode and cathode's connections and hook your water cooling system to the pipe fittings at either end.
