TAKE NOTE
Cosmetics: The appearance of different cases will vary after annealing.
Some cases will show distinct annealing discoloration at the neck and shoulder,
while other cases will show virtually no signs of being annealed. This is not
limited to any particular brands. Do not mistake appearance for successful
annealing. Some cases which appear heavily discoloured may not actually be
fully annealed. Our settings are reached by extensive and accurate testing of
the annealed hardness.
Thermal protection: In common with any induction heater, with extended use,
the output inductor will gradually heat up. Multiple fans are installed in our
annealer to keep the circuitry and inductor cool. After 40 - 50 cases have been
annealed, the top of the unit behind the pilot will start to feel warm to the touch.
This is normal.
In the rare event that the output inductor should reach 190F/90C (inside the
annealer), a thermal cut out will activate to protect the unit. If that occurs, leave
the annealer turned on so the fans continue cooling. It will automatically reset
after 30 minutes, once cooling is complete.
The ability of the annealer to run for the extended time depends partly on the
ambient room temperature. Avoid using in direct hot sunlight or high temperature
conditions. A room temperature of 70°F/20°F or below ideal.
Our Mark ll annealer should run virtually indefinitely on programs 1 – 126 or
AZTEC codes in the 0000 series (codes starting with a zero). When starting an
annealing session, the fans run at 55% power. This is to minimise fan noise. An
internal temperature monitor triggers full fan power if required. This trigger point
depends on the ambient temperature and program level being used. For high
power applications, full fan power usually starts after 50 – 150 annealing cycles.
For Standard programs less than 50, or for cartridges using a comparable AZTEC
code, the fans should remain on 55% power continuously.
Standard programs 127 – 200, and AZTEC codes in the 1000, 2000 and 4000
series are designed for very heavy duty annealing for cases in the WSSM family
and 50 BMG. They will cycle continuously for 100 annealing cycles before
automatically entering a “cool down” phase. This lasts for only 10 minutes, and
then resets to allow another 100 annealing cycles.
