The Wilton Model 8020 and 8120 Vertical Band Saws
are multi-purpose, metal cutting band saws that will
suit almost any metal working application. Typical
applications include contour sawing, beveling, slicing,
ripping, and stack cutting. The saws have a tilting
table and a useful speed and pitch selector. 'LJI~-\~~
Standard Model 8020 is equipped with a two-speed
gearbox. Higher speed Model 8120 is equipped with
a three-speed gearbox.

An optional blade welder, mounted on the saw,
provides a means to quickly weld and anneal new or
broken saw blades. The welder includes a blade
shear and weld grinder. (The welder is available in
220VAC or 440VAC power.)
Standard Model 8020 is connected for 220VAC
power unless otherwise specified. All models are
equipped with 3-phase, 220/440V, 115 V at switch
and magnetic starter.

You - the Stationary Power Tool User -
Hold the Key to Safety.
Read and follow these simple rules for best results
and full benefits from your machine. Used properly,
Wilton's machinery is among the best in design and
safety. However, any machine used improperly can
be rendered inefficient and unsafe. It is absolutely
mandatory that those who use our products be
properly trained in how to use them correctly. They
should read and understand the Operating Instructions
and Parts Manual as well as all labels affixed to the
machine. Failure in following all of these warnings
can cause serious injuries.

1. A set of start/stop push buttons, located below the
optional welder, provide a means to start and stop
the saw drive motor.
2. A variable speed control (crank), which can only
be adjusted while the saw is running, is located
below the start/stop buttons.
3. A blade tensioning hand wheel is mounted on the
top of the saw enclosure.

4. Referto Optional Welder for a description of the
weldercontrols.
The Model8020 band saw is equippedwitha two-
speed gearbox. The shift leveris locatedonthefront
of the band saw. Shift positions are L (low)and H
(high).
The Model8120 band saw is equippedwith a three-
speed gearbox. The shift leveris locatedonthe front
of the band saw. The shift positions are L (low),M
(medium),and H (high).
Optional BladeWelder
An optional blade welder is available on the vertical
band saw. The welder has all the features required to
cut, weld, and anneal the saw blade.
Welder Features
(refer to Figure 4)
The welder is installed on the left side of the saw
enclosure. A blade cutter, provided with the welder, is
mounted on the saw enclosure near the welder panel.

Operating the Welder
(refer to Figure 5)
WARNING: BE SURE TO WEAR EYE PROTEC-
TION WHILE OPERATINGTHE WELDER TO
AVOID EYE INJURIES. USE CARE WHEN HAN-
DLINGTHE BLADEAFTERWELDING TO AVOID
BURNS.
1. Usingthe bladecutter,cut the bladeto the
required length (ViewA).
2. Usingthe bladegrinder,square-offthe blade
ends (View B). The bladeends needto be
perpendicularto the side ofthe blade. The
bladeends mustbesquaresothere is minimal
gapbetweenthe endswhenclampedforweld-
ing.
3. Insertone endof the bladeinthe leftclamp
(ViewC). Positionthe back edge of the blade
againstthe back of the leftclamp. Then position
the endofthe blade midwaybetweenthe left and
rightclamps. Tightenthe leftclamp.
4. Insertthe other end ofthe blade inthe right
clamp. Positionthe back edgeof the blade
againstthe back of the rightclamp. Then butt
the end ofthe bladeagainstthe other end of
blade (the bladeends needto be incontact with
each other). Tightenthe rightclamp.
5. Setthe clamp pressureselector switch (clock-
wise rotation)to thesetting requiredfor the width
ofthe blade beingwelded(seethetable below). 9
NOTE: There will be some resistance when turning
the switch.
6. Pressand holdthe weld pushbutton. When the
pushbuttonis pushed,the rightclamp movesto
the leftto apply pressureto the blade ends. At
the sametime, sparkswill comefromthe blade
ends asthey are beingwelded.

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 Gog)the anneal pushbutton. Repeat
the depress-and-release process until you see a
red glow (slightly red) from the weld area.
CAUTION: DONOT PRESSAND HOLDTHE
ANNEAL PUSHBUTTON. THEWELD WILLBE

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 approximately
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: CHECKTHE BLADETO MAKE

THE BLADE ISTHICKERATTHE WELD,THE
BLADEGUIDESMAYBEDAMAGED.
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.

WARNING: NEVER OPERATE THE SAW WITHOUT
BLADE COVERS IN PLACE AND SECURED.
CAUTION: DONOTTURNSPEEDSETTING

1. Referto the Speedand Pitchselectoron the left
side ofthe saw enclosure. Select the speed

2. Shiftthegearboxto the requiredspeed setting
(Model8020: highor low) (Model8120: high,
medium,or low).
3. Start the saw usingthe start pushbutton.
4. Turnthe speed setting crankto the required
speed. Turningthe crankto the right (clockwise)
increasesspeed. Turning the crank to the left
(counterclockwise)decreasesspeed.
Blade Selection
The vertical band saw is equipped with a Wilton part
number 910839 saw blade that is adequate for a
variety of common materials. The blade is a 10-tooth,
1/2-inch multi-purpose.
(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 usedfor a solid steel bar
but a finer tooth blade used on a thin-wall tube. In
general, the bladechoice is determined bythe
thickness ofthe material;thethinnerthe material,the
finer the tooth pitch.
Forvery high productionon cutting of special
materials, or to cut hard-to-cut materialssuch as
stainless steel,tool steel, ortitanium, contactyour
industrial distributor for more specific blade recom-
mendations. Also,the supplierwho providesthe work
piece material should be preparedto provide you with
very specific instructions regardingthe best blade for
the materialandshape supplied.
