Carbon arc ?
I've used a twin carbon set up attached to a buzz box to bronze weld many times.
(Your rods could well be bronze, not brass, anyway.)

That's total gobbleaduke to me mate.
Adrian, TIG Brazing is a different process using uncoated rods, it (the filler) does not flow in the same way as it would in oxy / fuel brazing.Just thinking laterally but if you have one it may be possible to use a TIG torch to braze, just using the arc to provide the heat, I bet it is difficult though.
