HF arc by way of illustration
This arc with the traditional touch-starting methods are fundamentally different, without the tungsten
electrode and the workpiece perform short arc, is the use of high-voltage high-frequency pulses of air
ionization by ionization of the air ion conductivity, thereby an arc.
