ABSTRACT:
A spark gap device is described such as for use in welding systems. The device receives a high voltage, low current input signal and produces high frequency waveform output. The device includes one or more toroidal members surrounding a rod-like member with an annular gap therebetween. When the input signal is applied to the device, arcs are established in the gap between the toroidal members and the rod-like member, producing the high frequency output. Erosion and loci of arcs between the toroidal members and the rod-like member are distributed, resulting in extended life of the assembly. The gaps are also shielded from contaminants and moisture by an insolative body that maintains the toroidal members and the rod-like member in place with respect to one another.
