I'm not sure welding rods are the best choice for what you propose.
Since they will be arcing along the long edge, erosion will be minimal.
And since the rods are so small, air cooling will be poor.  Regular
copper pipe will be last a long time and have much better cooling.  For
adjusting the gap width, there's no easy and sound way to adjust the
individual spacing, although I have seen several creative attempts.
Most folks just adjust the number of gaps.
