    The initiation of a jet within MEW depends on the mass flow rate to the nozzle, applied voltage, and collector distance, and can take in the order of several or even tens of minutes, depending on the flow rate and/or melt viscosity. The molten jet is stabilized with the voltage and the whipping that is associated with electrospinning does not occur.

Hand torches can usually cut up to 38 mm thick steel sheet, stronger computer controlled torches can cut up to 150 mm thick steel sheet. Since plasma cutters produce a very hot and very localised “cone” for cutting, they are very useful for cutting and welding sheets in curved or angled shapes.
