A low current arc between the electrode and the constricting nozzle of the plasma arc torch to ionize the gas and facilitate the start of the welding / cutting arc.
A punched hole at (near) the plate edge of which the plasma arc cut is started.
A gas that has been heated by an arc to at least a partially ionized condition, enabling it to conduct an electric current.
An arc cutting process that uses a constricted arc and removes the molten metal in a high velocity jet of ionized gas issuing from the constricting orifice. Plasma arc cutting is a direct current electrode negative (DCEN) process.
