PERSONAL PRECAUTIONS
Control the tool, personal movement and the work
environment to avoid personal injury or damage to the tool.
1. Do not operate any tool when tired or under the influence
of drugs, alcohol or medications.
2. Avoid wearing clothes or jewelry that can become
entangled with the moving parts of a tool. Keep long hair
covered or bound.
3. Do not overreach when operating the tool. Proper footing
and balance enables better control in unexpected situations.
4. Support the workpiece or clamp it to a stable platform.
Holding the workpiece by hand or against your body may
lead to personal injury.
SPECIFIC SAFETY PRECAUTIONS
WARNING! DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence to the
tool safety rules. If you use this tool unsafely or incorrectly,
you can suffer serious personal injury.
1. Use the correct tool for the job. This tool was designed for
a specific function. Do not modify or alter this tool or use it
for an unintended purpose.
2. Failure to use the plastic welder correctly may result in fire,
damage and/or personal injury.
3. Keep hands and body clear of the welding head when
operating as it becomes very hot.
4. Do not leave the operating plastic welder unattended.
5. Do not allow the plastic welder to become wet or attempt
to cool the welding head with water.
6 Do not refill gas or store the butane soldering iron near a
naked flame, heater or combustible materials.
7. Do not drop, puncture or incinerate the butane soldering iron.
The butane gas is under pressure and damage may rupture
the unit.

8. Do not touch the butane soldering iron if it is venting gas.
The gas can cause a frostbite injury if it contacts skin.
9. Do not store or operate at temperatures above 50°C.
10. Let the plastic welder fully cool down before storing in the
molded case.

OPERATION
IGNITION
WARNING! All metalwork forward of the control section will
become hot and can cause a burn injury. Do not touch
welding head or metal body. Keep the tool away from
flammable objects until the soldering iron has time to cool.
1. Choose and fit a welding head (H) to the end of the butane
soldering iron (1). Fix in place with the screw.
2. Rotate the gas flow control (B) to the third position.
3. Press the ON/OFF switch (A) to the right, the ON position,
and press against the safety lock button (E). This frees the
ignition slider (F) for use and starts the flow of butane gas.
4. Slide the ignition slider (F) down in a quick motion to
ignite the flowing gas. The ON/OFF switch will remain in
the ON position.

5. Rotate the gas flow control to the second position to heat
the welding head. The catalyst block (D) will change from
white to orange as it heats up.
6. The heated air and gas are exhausted forward onto the
workpiece. To interrupt the gas flow, press and hold the gas
cut-off button (G). Releasing the button allows the gas to
flow again. Depending on how long the button was held,
the gas may need to be reignited.
SHUTTING OFF
1. Push the ON/OFF switch to the left, the OFF position. This
will stop the flow of gas.
2. Insert the soldering iron into the support slot (9) and let the
butane soldering iron fully cool down before replacing in case.
BUTANE SOLDERING IRON – BASICS
The plastic welding kit can be used for many types of repairs.
You can stop and resume a repair at any time as this is a heat-
based process and no chemical curing is involved.
1. Clean and prepare the surface by sanding with 120 to 180
grit paper to remove any paint, primer or dirt. This also
reduces the surface level compared to the surrounding area
that will be filled with plastic.
1.1 You may wish to feather the sanded area to help blend
the repair into the workpiece.
1.2 Drill a small hole at the end of a crack to prevent it
from splitting further before soldering.
2. Ignite the soldering iron and allow to heat up.
3. Direct the heated gas against the damaged area of the
workpiece to warm it up enough to melt with the plastic
rod when applied.
4. Insert the plastic rod that matches the material
composition of the workpiece through the opening in the
welding head (2 or 3).

5. Perform the following actions at the same time to add
plastic to the damaged area:
5.1 Press down on the damaged area so the welding head
is flat against the workpiece. Slowly draw the soldering
iron across the crack.
5.2 Apply pressure and feed the plastic welding rod
through the welding head opening.
6. Remove the plastic welding rod from the welding head. Should
an area require more plastic, reinsert the rod and repeat step 5
until you’ve added as much plastic as you desire.
7. Use the hot welding head to smooth and blend the plastic
into the workpiece.
8. Shut the butane soldering iron off and place the butt end
into the support slot (9) to allow to cool. Clean the welding
head with the brush (5) and cleaning rod (6) once it is cool
enough to touch.
9. The workpiece is ready for sanding to smooth the surface.
REPAIRING A LARGE HOLE OR CRACK
A hole or crack may be too wide to repair in a single pass.
Cover the gap with wire mesh.
1. Cut a strip of reinforcing mesh (7) to cover a gaping crack
or a hole. The mesh should rest below the workpiece’s
surface. The melted plastic will cover it and allow sanding
without exposing the mesh.
1.1 Apply the mesh to a curve to provide structural
support when soldering.
2. Tack the mesh to one end of the damaged area. Heat up
the area until you can press the mesh into the plastic.
Smooth the plastic over with the welding head.
2.1 You may need to tack more than one spot.
3. Follow the instructions for filling a crack. Press the rod
material hard enough so it will pass through the mesh to
cover the other side.

4. Make enough passes with the butane soldering iron to cover
the damaged area. Overlap each pass slightly to prevent
openings from appearing. This can weaken the area.
5. Smooth the plastic on the opposite side first if it won’t be
visible in the finished workpiece.
6. Complete the steps in Butane Soldering Iron – Basics.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is
efficient, easier to control and will have fewer problems.
2. Inspect the tool components periodically. Repair or replace
damaged or worn components. Only use identical
replacement parts when servicing.
3. Follow instructions for lubricating and changing accessories.
4. Only use accessories intended for use with this tool.
5. Maintain the tool’s labels and name plates. These carry
important information. If unreadable or missing, contact
Princess Auto Ltd. for replacements.
WARNING! Only qualified service personnel should repair the
tool. An improperly repaired tool may present a hazard to the
user and/or others.
GAS REFILLING
1. The butane soldering iron must be cool before refilling
with butane gas.
2. Ensure the switch (A) is turned to the OFF position
before filling.
3. Invert the soldering iron so the butt is up.
4. Insert the gas container's nozzle vertically into the gas
fill valve (C).
5. The soldering iron is full when gas escapes from the
fill valve.
