A tube is very flexible and does not require a high-powered laser. Laser generators with a power output of 12 kW are now possible for flat sheet cutting machines. Tube laser cutters require a power consumption of only 5 kW. To cut a tube you must always look at the opposite end of the tube. A stronger laser would simply blow through your tube while cutting. (Officially, if the laser is processing a beam and a channel on the tube's laser, there are no need to worry about any other side.
