Overview
EFR's F series CO₂ laser tube is an upgraded laser machine accessory equipped with a German discharge tube that has been galvanized with a catalyst. Its laser power reaches up to 200W, which is 30% more than traditional laser tubes. This cost effective classic CO₂ laser tube has a compact size, stable laser power, high-quality laser beam, great beam mode, a small light spot, a fast speed and a service life of up to 6,000 hours.

Parameters

Advantages
High Power: Equipped with a German discharge tube galvanized with a catalyst, this upgraded laser cutting machine replacement part has 30% more power than an ordinary laser tube of the same length, with a power up to 200W.

Reliable Stability: We carry out strict quality control during the firing process of the CO₂ laser tube, and ensure they have a guaranteed reliability and stability.

Long Service Life: Due to the galvanization of the catalyst inside and specially treated electrodes, the discharge tube has a better stability, and a long service life of up to 6,000 hours, ensuring long term reliable operations.

Performance and Applications: With a small light spot, stable performance and service life of 6,000 ours, EFR's 200W CO₂ laser tube can be applied to different laser machining equipment, including laser engraving machines, laser cutting machines, laser marking machines and laser die cutting machines.

We have supplied a number of laser equipment accessories for different laser engraving machine and laser cutting machine manufacturers. As they are popular among customers, the CO₂ laser tube is widely used in laser cutting, laser engraving, and laser marking in the advertising, packaging, craftwork processing, decorative building materials and leather product industries.

Cutting: F6, F8, and F10 CO₂ laser tubes are suitable for cutting materials in advertising, exhibition, decoration and other industries. These cost-effective glass laser devices can meet different processing requirements.

Engraving: F2 and F4 CO₂ laser tubes have excellent performances in laser engraving,, under preionization conditions and a current of 5mA. (F2 CO₂ laser tubes require a 4mA current). Our laser tubes can carry out high-frequency pulse engraving.

Operating Condition
Water cooling:
Cooling liquid: clean water;
Flow rate: 3-5L/min. (F2 CO₂ laser tube has the flow rate of 2-5L/min.);
Standard water temperature: 10℃-40℃
Ambient: temperature: 2℃ -40℃; humidity: 10-60%

Operating Current

The above current should be in accordance with actual currents displayed on the ammeter, which is in a series connection with the cathode.

If used incorrectly for long periods of time in over-current conditions, the CO₂ laser tube's negative electrode will change color, and the service life significantly decreased.

Cleaning Tips: When cleaning the window of the carbon dioxide laser tube, please do not use cotton swabs or other wipes as they will significantly affect the output power.

The following methods are provided for cleaning the window
1. When the lens is stained, turn off the laser tube.
2. Use an air dust blower to blow away dust and dirt on the lens.
3. Use a syringe to spray ethanol on the lens.
4. After the ethanol evaporates, turn the laser tube back on.
5. If the above methods do not work effectively, professionals are required, who will use a cotton swab dipped in ethanol to clean the lens in a rotating fashion away from the center, outwards to the edge.

Special Notice
1. Do not use acetone to clean the glass.
2. Do not move the two fastening screws on both ends of the laser tube, otherwise, the output power will decrease, and the laser tube will be scraped.
3. When testing the light spot on organic glass, please keep the organic glass 300mm away from the window.

Safety: As the CO₂ glass laser device generates invisible light, please wear eye protection gear when operating. A safety sign for high voltage is marked on the positive pole.

Storage and Transportation Requirements: When storing and transporting the CO₂ laser tube, please drain the cooling liquid and cover the tube ends with dustproof plastic bags. For storage, the required environmental temperature is 2-40℃ and the humidity ranges from 10-60%.

Adhesive tapes and sponges should be used to fix the laser tubes and prevent sliding during transport. A 70mm sponge should be use at the end of the window, and a 50mm sponge should be at the end of the fully reflecting mirror.
