14. Turn the pressure selector knob all the way
to the left so the clamp jaws are closest to
each other.
15. Insert the blade into the clamps so the weld
area is centered between the clamps.
Secure the blade in the jaws with the clamp
handles.
16. The annealing procedure involves “jogging”
(pressing and releasing) the anneal button
(Figure 19).
Do not press and hold the
anneal push button. The weld will be
overheated and will fail due to the excessive
heat.
How long to heat the weld depends upon
blade type:
Carbon Steel Blade: Jog anneal button until
the weld becomes a “dull cherry” to “cherry
red” color. Allow the blade to cool slowly by
decreasing the jogging frequency.
Carbon Steel Hard Back Blade: Heat slowly
until the weld becomes a “deep blue” color.
Continue to jog the anneal button until the
width of the blue color is one-half the length
of the band exposed between the jaws. See
Figure 21. Do not heat beyond the “blue”
stage – if the band begins to turn red, it is
too hot. Cool quickly by releasing the anneal
button.
Bi-Metal Blade: Heat slowly until weld just
begins to emit light ( a “dull red” color). The
desired color may be difficult to see in room
light – always shade the area with your
hand to see it better. Cool the weld quickly
by releasing the anneal button.
17. Release both blade clamps and remove the
blade.
18. Check the integrity of the weld. Bend the
blade to form a radius at the point of the
weld. The size of the radius should be
approximately the same as the radius of the
band saw drive wheel. The weld must hold
and not break or crack after forming the
radius. If the weld breaks, cut away the
welded area and repeat the welding-
annealing process.
19. Check to make sure the welded section is
the same thickness as the rest of the blade.
If not, grind off excess weld material using
the grinder (Figure 22). Figure 23 illustrates
some
un acceptable grindings.
