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).
