Damping factor function in AC electric arc models. Part 3. Static and dynamic properties of the arc with intense cooling in plasma torches

Antoni Sawicki

The importance of models of arcs with intense cooling has been shown in AC plasma torch design and usage. The influence of gas mass stream that washes plasma column on the shape of static and dynamic arc characteristics has been considered. The selected effects of functioning the high frequency auxiliary generator, leading mainly to stabilization of the arc and linearization of its characteristics have been analyzed.
