6. Press and hold the weld pushbutton. When the
pusbutton is pressed, the right clamp moves to
the left to apply pressure to the blade ends. At
the same time, there will be sparking from the
blade ends as the blade is being welded.
7. Release the weld push button and unclamp the
left and right clamps.
8. Rotate the clamp pressure switch (clockwise) to
the zero position.
9. Center the weld between the two clamps. Tighten
the clamps.
10. The weld is hard and brittle and must be annealed
before use. To anneal the weld, quickly depress
and release Oog) the anneal pushbutton. Repeat
the depress and release process until you see a
red glow (slightly red) from the weld area.

11. Release both blade clamps and remove the blade.
12. Check the integrity of the weld. Bend the blade
to form a radius in the blade at the point of the
weld. The size of the radius should be approxi-
mately the same as the radius of the 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.
CAUTION: CHECK THE BLADETO MAKESURE
THE WELDED SECTION ISTHE SAMETHICKNESS

THICKER ATTHE WELD, THE BLADE GUIDESMAY
BE DAMAGED.
13. 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
on the welder.

1. Start the saw usingthe start pushbutton.
2. Referto the Speed and Pitch selector on the left
side of the saw enclosure. Select the speed
setting for the material to be cut.

Blade Selection
The vertical band saw is equipped with a Wilton
part number 9108381 saw blade that is adequate for
a variety of common materials. The blade is a 10-
tooth, 1/2-inch multi-purpose blade. (Refer to the
speed and pitch indicator on the left side of the
vertical saw to select the blade and speed required
for various materials.)
A coarse blade is generally used for a solid steel
bar but a finer tooth blade used on a thin-wall tube.
In general, the blade choice is determined by the
thickness of the material; the thinner the material, the
finer the tooth pitch.
For very high production on cutting of special
materials, or to cut hard-to-cut materials such as
stainless steel, tool steel, or titanium, contact your
industrial distributor for more specific blade recom-
mendations. Also, the supplier who provides the
workpiece material should be prepared to provide
you with very specific instructions regarding the best
blade for the material and shape supplied.
Setting Blade Guide Support
(Refer to Figure 5)
The blade guide support must be adjusted for the
thickness of the material to be cut. Adjust the
position of the support as follows:
1. Loosen the blade guide support by turning the
handwheel on the front of the saw enclosure.
2. Place the material to be cut adjacent to the blade
guide. Move the blade guide support by hand
until there is clearance between the material to
be cut and the blade guide.
3. Tighten the handwheel.
