Abstract
An electric arc or plasma jet torch or heater has water-cooled electrode structures and a working gas injection arrangement which produce efficiently a very stable arc of maximum length at operating currents ranging from 20 amps to more than 400 amps so that the same torch can be used to satisfy a wide range of heating requirements.
