Try emersing your carbon gap in n2(nitrogen gas),this will stop the
flaming of the gap.I use carbon arc rods used in "old" projector
lamphouses,these rods are designed with copper centers to draw the heat
away from the arc.These rods are designed for lots of current 200+ amps
Use your n2 at low pressure,any questions just ask
