ed,
well i will take back the "anyone", i apologize.
and i do remember your telling me that you feel pure tungsten is better,
could you refresh my memory as to the benefits over carbide?
i know the melting point is slightly higher for pure tungsten, but i
think the sintering process does something to the carbide because i've
seen no erosion or melting of even the sharpest edges. to give an
example, on my triggered gap i use a small ball mill for the trigger
electrode, this ball has many fine teeth on it, after much firing the
teeth are still there, the pure tungsten rod i have has rounded over a
bit with time?
maybe pure tungsten has some redeeming qualities, i wont argue that, but
the fact that carbide comes in such a wide variety of shapes and sizes,
one for ANY design, and dull or chipped inserts run about $10.00 a
pound, makes it a great electrode for coilers like me, the low budget.
for those that might not know, pure tungsten and tungsten carbide are
two different critters.
