The device is hard work, we bought it for our team, we work as pipelayers, such a cutter has long been needed. Long chose, settled on this model. We work optimally with metal 4-6 mm, for this type of work CUT-40 is ideal. I didn’t like an ordinary gas cutter for a long time, I wanted something new. At the first use, you can see the difference, it cuts easier and faster, and not torn edges, but perfectly even ones. But, of course, this does not mean that everyone will succeed at once, as under the line. Of course, skill is needed. But such a cutter makes our work much easier, we began to do everything faster. The main thing is not to rush, but not to work with jerky movements, not to pull the nozzle, otherwise it will quickly burn out. With the right current and air, it is a pleasure to work. Even if it twitched somewhere, and an influx turned out, it is easily separated with a hammer. In general, with such a device it is faster and easier to work, and with it we get the most ideal cutting of metal.
