To protect surrounding surfaces from the heat gun cover with non-flammable material.
IMPORTANT: Do not concentrate the heat gun on windows or glass surfaces as the glass may crack.

PLASTIC WELDING TOOL (HS102 and HS102K )
Models HS102 and HS102K may be adjusted for use as a Plastic Welding Tool (welding kits available as described in part 3).
5.1.
Testing materials to be welded: Most adhesion failures may be due to the incorrect matching of materials. The welding rod
therefore must be of the same material as the item to be welded. For instance, most car body parts are made of ABS material.
Some manufacturers however, use different plastics in their products. To test, snip off a piece of material from the work to be welded
and proceed as follows:
5.1.1.
Set light to the sample with a naked flame. If the flame gives off black smoke it is (almost) certain to be ABS.
5.1.2.
By sample, take a strip of material from an unobtrusive part of the component and use it as your welding rod.
5.1.3.
If in doubt, contact the item manufacturer.
DANGER: Step 5.1.1 must be performed in a well ventilated area, (out of doors if possible). Never perform task in a domestic building. Safeguard fire. Wear safety gloves
and face mask. DO NOT inhale smoke.
5.2.
Welding the material:
5.2.1.
Remove any paint or other covering from the entire adjoining surface areas of the pieces
to be welded.
5.2.2.
Cut a chamfer on adjoining pieces to form a groove that can be filled with weld.
5.2.3.
Using the hot air gun (without any welding rod loaded) thoroughly pre-heat both surfaces to
be welded (they should be soft but not tacky).
5.2.4.
Fit the 9mm reduction nozzle to the gun and the welding nozzle to the reduction nozzle.
5.2.5.
Select a low to medium heat by turning the temperature regulator at rear of the gun (fig A).
Experience will determine the setting, but we suggest position 3 which gives 250-350°C as
a starting position for most commonly used plastics.
5.2.6.
Select the fan speed setting on the hot air gun according to the size and thickness of material
being welded (i.e. Thin = Low, Thick = High).
5.2.7.
Now position the nozzle over the material to be welded and feed the welding rod through the
slot at the same time moving the gun along the groove at a speed according to the melt/
adhesion rate (fig B).
5.2.8.
A good connection is made when a small dome forms (a trial is always recommended using
an odd piece of material). With practice, a good flat weld can be achieved by applying
pressure on the nozzle as the rod is drawn along. A roller is available as an optional extra.
5.2.9.
Overlapping materials can be removed with a sharp knife.
5.3.
Welding problem checklist. If a weld fails ask yourself the following questions:
5.3.1.
Do the materials match?
5.3.2.
Are both surfaces clean?
5.3.3.
Are surfaces chamfered?
5.3.4.
Have surfaces been pre-heated correctly?
5.3.5.
Did the welding rod melt to the correct consistency?
5.4.
Important notes.
5.4.1.
To weld over cracks in the material, drill approximately 1/16”mm diameter holes at each end
of the crack to prevent running during welding and sanding.
5.4.2.
Handling the welding nozzles - The nozzle becomes very hot and should only be removed
with pliers or allowed to cool if removing by hand. Welding nozzles can only be used with
Temperature Regulated Gun HS102/HS102k. DO NOT use the plastic welding nozzles with
HS100CE single heat gun as the small nozzle diameter will cause the gun to overheat.
6.
CARE AND MAINTENANCE
6.1.
Keep the air intake and outlet openings clean and free from dirt and peelings.
6.2.
Only use a damp cloth and mild household cleaning agent to wipe the gun clean. DO NOT use turpentine, paint thinner,
gasoline, or similar substance to clean the gun.
6.3.
Check the gun, power lead, and nozzles for damage before storage.
6.4.
Store the gun in a safe dry area.
7.
OTHER TASKS
The gun may also be used for the following: Removing self-adhesive stickers and trim / Loosening rusted or over-tightened nuts and metal
screws / Thawing frozen pipes, frozen doors, padlocks, etc. / Defrosting ice-compartments / Highlighting natural woodgrain before staining,
or varnishing / Fast drying of paint or varnish / Softening old putty / Drying wet timber prior to repairs or finishing / Shrinking PVC shrink-wrap
sheeting / Shrinking polyvinyl wire joints / Soldering / Sterilisation 500°C / Removing candle wax / Restoring candles / Binding of engine parts /
Repair of tarpaulin or PVC / Joining garden hose / Liquifying pewter, tar, bitumen or wax / Model making / Moulding pvc, wood, copper, Plexiglass
into shape / Plumbing tasks / Roofing repairs / Applying veneer strips / Control of garden path weeds / Waxing and de-waxing skis / Chemistry,
use as a bunsen-burner / and more.
Important: Safety is a key principle when endeavouring to use the gun for different tasks. When approaching a new task consider the potential
dangers that may arise, take any necessary precautions and practice before attempting the job.
