40 Watt
Perhaps you have noticed that we haven’t yet discussed cutting speed. Although it is possible to cut 500 inches per minute with a tube, this is not always feasible. Laser tube cutting should not be about how long it takes for a tube to be loaded, indexed so that it is in the right place for cutting, pierce it and then unload it. Laser tube cutting machines are more concerned with part-processing times than cutting speed.
Imagine that you need to put a through-hole at the center of a tube. It must be centered to the actual dimensions, not just one. This will make things more complicated. This is how tube manufacturing works.
