ANNEALING THE WELDED BAND
(1) Swing the weld lever up all the way to the anneal' position which
is marked by the letter "A". The lever will be held in place by the
bend in the drag spring.
(2) Clamp the band just as in welding.
(3) Set the anneal heat selector switch for the width of the band.
(4) Anneal the band as explained below.
Follow these instructions carefully.
(a) For Carbon Blade: Press and jog the annealing switch button
until the weld is a dull cherry to cherry red color. Allow
the blade to cool slowly by decreasing the jogging frequency.
(b) For Dart Blade: Heat the blade slowly until the weld becomes
a deep blue color. Continue to heat by jogging the anneal
button until the width of the blue color is one-half the
length of the band exposed between the jaws. Do not overheat
or the temper of the band will be damaged.
Do not heat beyond the blue state - if the band
begins to show any red color, it is too hot.
Coot quickly by releasing the anneal button.
Correct annealing of Dart Blade.
(c) For IMPERIAL BI-METAL Blade: Heat the band slowly by jogging
h button until the weld just begins to emit light
(this would be the dullest red color). The desired color may not be
visible in normal room light. Always shade the weld area with your
hand.' Cool the weld quickly by releasing the annealing button.
NOTE: This procedure should be followed both before and after
grinding IMPERIAL BI-METAL Blades.
