Safety for Blade Welders
WELDING FUMES. Breathing welding fumes can
cause respiratory damage. Maintain adequate ventilation during and after welding operations.
PREVENT FIRES. Welding work zones must be
kept clear of flammable liquids or gases, such as
gasoline or solvents, and combustible solids, such
as paper or wood, especially any built-up dust
from this same material. Provide approved fire
extinguishing equipment for the welding zone. Stay
alert for sparks and spatter thrown into cracks and
crevices that can start a smoldering fire.
PERSONAL PROTECTIVE EQUIPMENT. Wear
eye and body protection approved for welding operations, such as safety goggles, a face shield, clean
and oil-free protective clothing, leather gloves, long
sleeves, and cuffless pants. Protect other people
and property in the welding work zone from exposure to sparks and hot spatter.
STABLE WORK SURFACE. Always make sure
the welder is mounted on a stable and lever surface before operations. If the welder unexpectedly moves during operation, burns, lacerations, or
abrasion injuries could occur.
ABRASION INJURIES. The grinding wheel can
remove skin very quickly. Always keep your fingers
and hands away from the spinning grinding wheel
to reduce this risk.
ELECTRIC & MAGNETIC FIELDS (EMF). Welding
operations create EMF around the welding equipment and workpieces. Workers who have pacemakers must consult with their physician before
using this equipment or stay at least 50 feet from
welding operations.
EQUIPMENT MAINTENANCE. Make sure equipment inspections and maintenance are performed
by a qualified person. Stop the welding operation
and disconnect the welder from power if the equipment is damaged or malfunctions.
BLADE BREAKAGE. Blades that are not welded
correctly can break under the stresses of using
them on the bandsaw. Have only one weld on a
blade. Always inspect the weld as instructed. Make
sure the annealing and grinding process does not
compromise the integrity of the weld. If you have
any doubt about weld quality, start over.
If you have never used this type of welder before, WE STRONGLY RECOMMEND that you read
books, trade magazines, or get formal training before beginning any projects. Regardless of the
content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of
training.

Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
Circuit Information
or equipment damage
not properly grounded
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.
For your own safety and protection of
We do not recommend using an extension cord
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:

Operations
Overview
This blade welder uses electrical resistance (induction) to weld bandsaw blade ends. Afterwards, the
annealing process gives the weld strength and
flexibility.
Hot sparks from the welding process can
damage your eyes and skin. During welding
operations, always wear safety goggles and
protective gear to reduce your risk.
Blade Shear
To use the blade shear, place the back of the
blade evenly against the back of the blade shear,
as shown in Figure 5, then firmly pull the handle
down to square off the blade end.
Blade Preparation
When welding the blade, the ends must evenly
butt up against each other and be square. This
will ensure the that the weld is of even thickness
for the full width of the blade.
To prepare the blade for welding:
1. Be sure to grind off any teeth that are in the
blade welding zone (see Figures 6–7).
Note: Make sure the blade ends are even
with each other after grinding them.

Figure 7. Using the grinder.
T27555-75 Blade Welder (Mfd. 12/15+)
Note: You can make sure that the blade ends
are even with each other by stacking them
together with the teeth facing in opposite
directions (see Figure 8), then grinding them.
Regardless of the grinding angle, the blade
ends will match evenly for welding.
Figure 8. Blade ends stacked with teeth facing
opposite directions.
2. Use 120-grit emery cloth or an equivalent to
lightly sand the part of the blade that will contact the welding clamps. This helps ensure
a good electrical contact with the blade for
welding.
Note: To prevent dulling the teeth, keep the
emery cloth away from them when sanding
the blade surface.
Welding
1. DISCONNECT WELDER FROM POWER!
2. Thoroughly clean the welding clamps to
remove debris, oily substances, or flash from
previous welding operations. If necessary,
lightly sand clamps with 120-grit emery cloth.
3. Fully rotate the clamping pressure dial
(see Figure 9) clockwise. This spreads the
welding clamps apart to allow proper positioning of the blade ends.

4. Loosen the welding clamps by pulling the
clamp levers down.
5. Position the back of one blade end evenly
against the back of the right welding clamp so
the end is midway between the two clamps,
then rotate the clamp lever as far up as possible to hold the blade end in place (see
Figure 10).

6. Use the illustration in Figure 11 to set the
correct clamping pressure setting for the
width of the blade.
Note: The clamping pressure presses the
blade ends together to help form a strong
weld. The pressure scale is an approximation
only. If you have difficulty getting satisfactory
welds, experiment by increasing or decreasing this pressure.
Note: To ensure a good blade weld, it is
critical that the blade ends are secured in the
welding clamps evenly and with no overlap
(see Figure 13).

Burning sparks may be thrown in all directions while welding. Protect yourself from
injury by not welding near flammables and
wearing spark-resistant clothing/gloves.
Keep fire extinguishing equipment readily
available.
NOTICE
For good metal-to-metal contact between
welding clamps and blade, make sure
blades and clamps are free from any debris,
coatings, or flash before and after each use
of the welding station.
T27555-75 Blade Welder (Mfd. 12/15+)
Before welding a blade back together to
perform an internal cut, insulate entire blade
from all metal surfaces of the bandsaw to
ensure a good flow of current through the
blade.
10. Press welder button until the blade joint
returns to the original color. IMPORTANT:
Releasing the welder button immediately
may cause weld failure.
Note: A limit switch senses the electrical
resistance between the blade ends. If there is
an adequate amount of welded material, the
limit switch will not allow the welder button to
activate the operation again.
14. Inspect the weld. The welded joint should be
even across the width of the blade with no
gaps (see Figure 14).

12. Rotate the clamping pressure dial fully clock-
wise to release the clamp pressure.
13. Remove the blade.
— If the weld is satisfactory, anneal the weld
as instructed in the next subsection.
— If the weld is NOT satisfactory, use the
blade shear to completely remove the weld
and repeat the Blade Preparation and
Welding procedures beginning on Page 6.

Annealing Weld
Once the blade ends are welded, the metal
becomes hard and brittle, which is not suitable
for a bandsaw blade that must continuously bend
smoothly under stress.
5. Allow the blade to completely cool.
6. Remove the blade from the welding clamps.
7. Grind the weld flat on both sides so the blade
will run smoothly on the bandsaw wheels.
To bring the weld strength and flexibility to acceptable levels for a bandsaw blade, it must be
annealed. The annealing process re-heats the
weld area, then allows it to cool gradually, improving its strength enough to meet the flexibility
requirements for the blade.
To anneal the weld:
1. Place the blade in the welding clamps so that
the weld is centered between the clamps.
2. Secure the blade by moving clamp levers up.
3. T27556 Only: Set the "Anneal Strength"
switch (see Figure 15) to the proper position for the width of the blade. Use WEAK for
1
⁄8"–3⁄8" (3–10mm) wide blades and STRONG

Note: Make sure not to grind the teeth or
blade body. Be careful to avoid overheating
the blade while grinding—this will weaken the
blade.
8. For Bi-Metal Blades Only: Repeat Steps
4–5 (not Step 6).
9. Test the strength and flexibility of the weld by
bending the blade in an arc (with the weld at
the top of the arc) similar in size and shape of
the bandsaw wheels. The blade should bend
smoothly without any angles (see Figure 16).
