Portable flame cutting machines, like those large flame cutting machines, also need to use flames for cutting. However, the speed of this portable flame cutting machine is much faster than that of ordinary large cutting machines, and it can cut very thick materials, such as 5mm, 10mm, 20mm, 50mm, etc. Moreover, the maximum thickness that can be cut has reached 150 millimeters, which is on par with large cutting machines. However, there is one aspect that cannot be compared with large flame cutting machines: its maximum width can only be three meters. Therefore, if you want to purchase a portable flame cutting machine, it is best that the width it needs to cut should be within three meters.
