We use semi-automatic welding and electric arc from Aurora, I hoped that the plasma would be just as reliable. Now I am choosing a new plasma substitution, but from a different manufacturer Has pros: It performs its functions, it is a very convenient thing for dismantling, cutting by hand is not particularly successful, cutting 6-8 mm is the very thing! Different cons: Broke after several times of use, the repair took several weeks, not all service centers take repairs
