Plasma torch with arc current standing up mobile longitudinally and method for controlling its displacement.

摘要

The invention relates OF HOLDERS WITH PLASMA FORMED AN ELECTRODE UPSTREAM (12), an electrode DOWNSTREAM (11), a chamber (15) gas injection plasma generator A trigger electrode (13) and SOMETIMES A MAGNETIC FIELD COIL (14) where ARCH FOOT MOVES ON ELECTRODE UPSTREAM. According to the invention, TO DOMINATE A CONTINUING FORWARD OR ALTERNATIVE AND / OR oscillatory, feeds FIELD COIL AND DC VARIABLE, IF POSSIBLE WAVY PULSANTE, AND / OR SITUA a diffusor ON BACKGROUND OF ELECTRODE UPSTREAM THAT FEEDS With a volume of gas mODULATED Whirls. APPLIED TO THE HOLDERS FOR PLASMA HIGH POWER TO REGULATE AND WEAR UNIFORM electrodes to maximize the life.
