The 70 W is definitely an investment and best for professionals that work on larger-scale projects. The machine itself is also quite big, so make sure there’s room for a 126 x 87 x 92 cm cutter. PLEASE NOTE: Frequent use of high laser power settings will shorten the laser tube lifetime as follows: The Flux Beamo 30 W is listed as an entry-level laser cutter, and it absolutely is in terms of ease-of-use, however, with this price point, we recommend it as an entry-level cutter for small businesses rather than individual use.
Another OMTech model to consider is its new Polar 350. This machine is fairly different to other OMTech machines as the Polar 350 is a more modern and intuitive machine, with more quality-of-life features that make it easier to use.

Now is the Time for Training!
Cranktown City]’s build style is refreshingly informal, but there’s a lot going on with this build that’s worth looking at — although it’s perhaps best to ignore the sourcing of glass tubing by cutting the ends off of an old fluorescent tube; there’s no mention of what became of the mercury vapor or liquid therein, but we’ll just assume it was disposed of safely. We’ll further assume that stealing nitrogen for the lasing gas mix from car tires was just prank, but we did like the rough-and-ready volumetric method for estimating the gas mix.
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. collisionally de-excites by transferring its vibrational mode energy to the CO 2 molecule, causing the carbon dioxide to excite to its {v3(1)} (asymmetric stretch) vibrational mode quantum state. The CO Storage and Transportation Requirements:When storing and transporting the CO 2 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%. is continuously pumped through it. The specific proportions vary according to the particular laser. The first thing to consider is your experience. If you’re new to the game of CNC machines, regardless of how experienced you are as an engraver or carver, then you’ll want an entry-level laser cutter. These will be the easiest to use and often the cheapest option available and ensure you’re not out of thousands if you make a mistake while learning.
Each tube will have a date of manufacture printed on the main label. Ideally, this needs to be as close to the current date as possible, but it’s not unusual for this to be up to two months old. This is important as the manufacturer’s warranty starts from the date of manufacture, not the date of delivery. 8. Maintenance of the Optical Path:
Other upgrades include automatic laser focusing, although manual focusing is still streamlined and easy. The active laser medium (laser gain/ amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied. The filling gas within a sealed discharge tube consists of around 10–20% carbon dioxide ( CO TEMOO MODE】- The co2 laser tube adopts the TEMOO mode, which is characterized by high spot concentration, high energy density as well as good and stable spot. At the same time, the use of output mirrors further enhances the mode.
Which Laser Machine is Right for you?
A CO2 laser’s size and working area can vary a lot, and also has a big impact on price. The Flux Beamo is one of the smallest and cheapest machines, with a working area of just 300x210mm designed for small projects. Its cutting depth sits at around 2-3 mm, giving you confident single pass cutting, and has a laser pointer for pinpoint accuracy. Despite its size and price, the 40 W also comes with optimized ventilation, sporting a flexible tube and internal fan that help target smoke output away from your work area.
The video below shows the whole process of building and testing the tube. Initial tests were disappointing, but with a lot of tweaking and the addition of a much bigger neon sign transformer to power the tube, the familiar bluish-purple plasma made an appearance. Further fiddling with the mirrors revealed the least little bit of laser output — nowhere near enough to start cutting, but certainly on the path to the ultimate goal of building a laser cutter. cutting, welding and cladding metals such as stainless steel, aluminum or copper, applying multi-kilowatt powers Because the excitation energy of molecular vibrational and rotational mode quantum states are low, the photons emitted due to transition between these quantum states have comparatively lower energy, and longer wavelength, than visible and near-infrared light. The 9–12μm wavelength of CO 2 lasers is useful because it falls into an important window for atmospheric transmission (up to 80% atmospheric transmission at this wavelength), and because many natural and synthetic materials have strong characteristic absorption in this range. [3] If used incorrectly for long periods of time in over-current conditions, the CO 2 Laser tube's negative electrode will change color, and the service life significantly decreased.
Competition with Solid-state Lasers
CO 2 lasers used for laser material processing (e.g. welding and cutting of metals, or laser marking) are in competition with solid-state lasers (particularly YAG lasers and fiber lasers) operating in the 1-μm wavelength regime. These shorter wavelengths have the advantages of more efficient absorption in a metallic workpiece and the potential for beam delivery via fiber cables. (There are no optical fibers for high-power 10-μm laser beams.) Besides, 1-μm beams can be more tightly focused, provided that the beam quality is high. However, the latter potential normally cannot be realized with high-power lamp-pumped lasers, and diode-pumped lasers tend to be more expensive. Concerning absorption, CO 2 laser beams are actually quite favorable for certain materials like polymers and ceramics. Even when absorption is less favorable than for a solid-state laser, a CO 2 laser may be preferred as a relatively cheap and robust solution. A substantial disadvantage, however, is that there are no high-power fiber cables for CO 2 laser radiation. Stable Laser Power: We use special equipment and US imported gas to allow this laser consumable to have a stable laser power, effectively slowing down the dissociation rate of working gas, and prolonging the service life. As the rated operational power for RECI tubes, an average stable maximum is stated, not the peak value. Thus, in comparison with its analogs, RECI tubes turn out to be a little more powerful. Their life-time is up to 10 000 hours (if meeting the requirements of operation conditions recommended by the manufacturer). The average life-time, as a rule, does not exceed 5000-7000 hours.
