The plasma gas does not come in contact with electrodes, thus eliminating possible sources of contamination and allowing the operation of such plasma torches with a wide range of gases including inert, reducing, oxidizing, and other corrosive atmospheres.

The National Shipbuilding Research Program ( NSRP ) has also hosted work to implement a prototype that connects a shipyard design system to a plate cutting using STEP-NC . This work involved extending STEP-NC to steel plate cutting and marking using plasma torches.

All were scrapped following withdrawal, except two ( 79047 + 79053 ), which were taken into departmental ( non-revenue earning ) service as 975018 + 975019 . They were used at the Railway Technical Centre in Derby as " Laboratory 21 : Plasma Torch Research ".

For example, a research plasma torch at the Institute of Plasma Physics ( IPP ) in Prague, Czech Republic, functions with an H2O vortex ( as well as a small addition of argon to ignite the arc ), and produces a high temperature / velocity plasma flame.

The handle would be a plasma torch with the base of a dyetanium fan that would shoot about one hundred feet of cubic air per second into the hilt where it would be heated to twelve thousand degrees of plasma which would be kept intact by an electro-magnetic coil.

Other related devices are " vacuum testers " or " Tesla / Oudin coils " for igniting glow-discharge in plasma devices, visually testing gas mixtures and locating pinhole leaks in neon signs and chemistry glassware, for plasma surface treatment, locating leaks in plastic tank liners, and igniting ( ( Inductively coupled plasma | ICP analyzers') ) argon plasma torch.
