The regression analysis was used in [9] for the development of empirical models able to describe the effect of the process parameters on the cut quality in
plasma arc cutting of a 15 mm thick mild steel sheets.

The method also eliminated machining of hard edges, caused by metallurgical changes wrought by laser or
plasma arc cutting.
Plasma Arc Cutting is a process where an open arc can be constricted by passing through a small nozzle, from the electrode to the workpiece.
Students in Welding II complete study in occupational orientation and safety, advanced shielded metal arc welding (SMAW), semi-automatic arc welding [gas metal arc welding and flux-cored arc welding (GMAW/FCAW), gas tungsten arc welding (GTAW), carbon arc cutting principles and practices (CAC-A),
plasma arc cutting (PAC), and employability skills.
Among the unconventional cutting processes, the
Plasma Arc Cutting process is a significant one.
Normally, a
plasma arc cutting system has a power supply, an arc starting circuit, and a torch.
