A spark gap assembly for a welding power supply includes at least one pair of spark gap points and a housing base including at least one base groove for axially aligning the spark gap points. Point stops are disposed to retain some of the spark gap points in the spark gap assembly. Insulating walls and insulating channels are disposed to reduce the possibility of shorts occurring between various spark gap assembly components or between spark gap assembly components and other power supply components.
