With this in mind, the machining technician can have complete control over the cutting process, from arc fire to extinction. This stroke provides decent performance and significantly reduces the time required for edgebanding.

In order to ignite the torch in the device, you just need to bring the cutting part of the device to the surface of the metal structure at a distance of within 1 millimeter and push the button on the cutter. As a consequence, contactless ignition of the torch will occur and the process of processing or cutting will follow. It is worth considering that in the process there is absolutely no sticking of the tip of the cutting tool and the surface of the metal structure. During processing, material warpage or any similar defects are not detected. In addition to all of the above, contactless ignition of the arc quite quickly reduces the wear of consumables, and also makes it possible to cut metal materials taking into account the holes without stopping.

Taking into account the maximum operating current of one hundred amperes, this plasma cutting device is capable of producing a cut of metal structures with a thickness of more than 40 millimeters. Taking this into account, the PV will not fall less than 65 percent, and such a stroke makes it possible to process for a rather long time with high intensity.
