Tool Description
Powder coating with the Model T25100 is a superior alternative finishing process to wet painting on
metal parts. A few of the advantages of powder
coating are high durability, high-impact and stress
resistance, and uniform control of finish.
The powder coating process uses a dry, finelyground polymer of various types and mixtures that
is electrically charged and applied onto the metal
workpiece through electrical attraction. After completing the powder application, the finish must be
cured (baked) in a dedicated electric oven.

Additional Safety for Powder Coating
Systems
ELECTROSTATIC GROUNDING. The powder
coating system electrically charges the powder
and gun during application. To prevent electrical
shock or dust explosion from electrostatic sparks,
make sure that the power circuit, control box, and
workpiece are well grounded. Make sure your
body is well grounded to an earth ground, not the
powder coating system—use a grounding strap if
standing on non-grounded or insulated surface.
PERSONAL HEALTH. Powder used in this tool
can cause eye, lung, and skin injuries with sustained exposure. Always wear ANSI-approved
goggles/face mask, NIOSH-approved respirator,
non-insulating gloves, and anti-static clothing that
will protect your skin when handling the powder
and during application.
DUST EXPLOSION. The finely-ground powder
is flammable when floating in the air. Stay at
least 50 feet away from any ignition source (e.g.,
open flame, hot water heater, welder, etc.) when
handling the powder or during operation. Keep a
multi-class fire extinguisher in the immediate work
area.
AIR PRESSURE. Using air pressure with this tool
that exceeds 30 PSI could cause the spray gun
to break apart, which could result in impact injury
or explosion. Never exceed 30 PSI of air pressure
during operation.
ELECTRIC SHOCK. To avoid electrical shock
when tool is connected to power, never touch conductor pole that protrudes from the gun nose—the
conductor pole is electrically charged! After turning the control box OFF, touch the conductor pole
to the grounding clip to discharge current. NEVER
touch the metal workpiece during operation—it
is also electrically charged! Do not use tool if
you have electronic medical devices (e.g., pacemaker).
CURING FUMES. The fumes produced during
curing can cause severe eye, lung, and skin injuries. Always make sure the oven is well-ventilated.
Always wear ANSI approved goggles/face mask,
respirator, and clothing that will protect your skin
when exposed to curing fumes. DO NOT use a
gas oven that could cause the fumes to explode—
only use an electric oven. DO NOT use an oven
that will be used for cooking food. Always keep
the oven at least 50 feet away from any ignition
source during the curing process—the fumes are
volatile!
No list of safety guidelines can be complete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other equipment with caution and
respect. Failure to do so could result in
serious personal injury, damage to equipment, or poor work results.

Model T25100 (Mfg. Since 8/12)
Operational Points
Adhere to the following points for the best
powder coating results:
• Use a side-to-side overlapping pattern when
spraying. Most powder products require a
coating of approximately 2mm. Check the
powder manufacturer's specifications and
practice attaining the correct thickness on a
scrap workpiece.
• The workpiece MUST be clean of debris,
paint, or other non-metal material. Depending
upon the application, cleaning may be as
simple as using mineral spirits and clean
rags, or it may require a much more complicated "pre-treament" process, such as sandblasting.
• Obtaining good powder coating results
depends on many variables—workpiece pretreatment, powder chemical composition,
method of spraying, curing procedure, etc.
Read books, use online resources, or talk to
professionals to gain an understanding what
is required for your operation.
• Use only high-quality powder coatings.
Investigate the many powder options on the
market and choose the one that best suits
your application.
• Use only pressurized air that is clean, dry,
and free from oil.
• Make sure the system ground clip is firmly
secured to the workpiece or hanger with good
metal-to-metal contact.
• You MUST “cure” the workpiece to complete
the powder coating process. The curing oven
must have good ventilation. Poor air circulation can cause discoloration or hazing.
Fumes from the curing process are poisonous! Make sure the curing oven is well-ventilated. Use a dedicated electric oven that
will NOT be used for cooking food.
• Follow closely the powder manufacturer's
directions for curing. Under-curing can result
in poor physical qualities and over-curing can
change the color.
• Always maintain clean powder cups, spray
gun, and work area. Contamination of powder products by debris or other powder material can produce unexpected results.
• Some orange peel effect may be unavoidable. If this happens, wet-sand the workpiece
with 400 grit sandpaper, thoroughly dry the
workpiece, and repeat the coating process.
• To begin spraying, depress the foot switch
and spray gun trigger simultaneously. The
foot switch enables power to the gun conductor pole, which electrically charges the dust
as it leaves the gun. The spray gun trigger
allows air to flow through the powder cup and
gun to send the powder onto the workpiece.
• Use the air pressure regulating valve and
powder flow regulating screw to control the
flow of powder through the spray gun.
• Experiment with the scatter tips to gain an
understanding of the effects attained with
each tip.
Model T25100 (Mfg. Since 8/12)
• To remove slight imperfections, buff the
workpiece with a loose buffing wheel and
white rouge compound.
Exposure to powder coating materials can cause eye,
lung, or skin injury. Always
wear ANSI-approved goggles, NIOSH-approved respirator, and wear clothing
that will protect your skin.
-13-
Workpiece
Preparation
The powder coating system is designed to
ONLY operate on solid, electrically-conductive metal workpieces.
Follow these workpiece preparation guidelines for the best results:
• Thoroughly clean the workpiece of paints or
other finishes, residue left by cleaning solutions, debris, dust, and any other foreign
material. Depending upon the application,
additional pre-treatment steps may be necessary.
• Make sure the workpiece is completely dry.
• Use clean metal material for workpiece hangers. This will ensure that the hanger is
grounded with the workpiece.
Scatter Tips
The Model T25100 ships with three scatter tips
with diameters of
1
⁄2 ", 3⁄4", and 1" (see Figure 9).
• Attach the grounding clip (see Figure 8) to
the workpiece or hanger with a good metalto-metal contact at a point where the powder will not be applied. This will provide a
negative electrical attraction for the charged
power.
Figure 8. System grounding clip.
• Make sure the workpiece is not touching any
other grounding source other than the powder coating system ground.
Figure 9. Included scatter tips.
The scatter tips thread onto the conductor pole
(see Figure 10) and produce different spray patterns. Experiment with a scrap workpiece to gain
an understanding of the effect that each tip produces.
Note: Wipe the tips clean of powder before storing them.

The spray gun conductor
pole may be electrically
charged. Always disconnect the system from power
and ground the conductor
pole to the system grounding clip before making contact with conductor pole to
reduce the risk of electric
shock or dust explosion
from electrostatic sparks.
Powder Cups
During operation, air circulates inside the powder cup to produce a fine dust, which is then fed
through the spray gun and onto the workpiece.
5. Connect the tool to the air supply (but NOT
to power) and use the spray gun trigger to
send air through the gun to make sure any
residual powder from the last operation is
cleared away.
6. Remove the powder cup from the spray gun
and fill it with up to 2" of powder.
Note: Leaving space in the powder cup
allows the powder to circulate into a fine dust
when the air is applied.
7. Make sure the gasket is in place inside the
mounting cap, then turn the gun upside down
and thread the powder cup onto the mounting
cap (see Figure 12).
To fill and attach the powder cup:
1. DISCONNECT TOOL FROM POWER!
2. Put on eye, lung, and skin protective gear.
3. Make sure the powder cup, gasket, and
mounting cap components (see Figure 11)
are dry and clean of any powder or debris.

Curing
Curing the powder coating is a process that melts
the powder into an even finish that adheres to the
workpiece. This is done with a dedicated electric
oven that is not used for any other purpose.
Follow the powder coat manufacturer's recommendations for curing temperature and length of
time to produce good results.
Figure 11. Powder cup components.
4. Insert the gasket into the mounting cap, then
thread the empty powder cup onto the mounting cap.

The powder coating will NOT adhere to the
workpiece unless it is properly cured in a
dedicated electric oven. Follow all recommendations made by the power coat manufacturer for properly curing their product.
