Applications
(F) Soft soldering:
First, clean
metal parts you want to join.
Then, using hot air, heat the point
you want to solder and offer up
the soldering wire. Use flux or a
soldering wire with a flux core to
prevent oxide forming.
(G) Welding and joining plastic:
All parts being welded must be of
the same plastic material. Use an
appropriate welding rod.
(H) Hot-tool welding
on plastic
pipes or rods. The ends are
pressed against a coated hot tool
and then joined together.
Here are some of the applications
you can use BETA hot air
guns for. This selection is by no
means exhaustive – no doubt you
can immediately think of other ex-
amples.
(A) Stripping paint:
Paint is soft-
ened and can be removed with a
stripping knife and paint scraper
to leave a clean surface.
(B) Shrinking tubing on cables:
The shrink tubing is slipped over
the section you want to insulate
and heated with hot air. The tub-
ing shrinks by approx. 50 % in
diameter to give a sealed union.
Shrinking is particularly fast and
even using reflector nozzles.
Sealing and stabilising cable
breaks, insulating soldered joints,
gathering cable runs, sheathing
terminal blocks.
(C) Forming PVC:
Sheeting,
piping or mouldings can be soft-
ened and formed with hot air.
(D) Shaping:
Ski boots and
sports shoes can be shaped for a
perfect fit.
(E) De-soldering:
Electronic com-
ponents are detached quickly and
neatly from circuit boards with a
reduction nozzle.
(I) Joining sheeting:
The sheets
are overlapped and welded
together. A slit nozzle is used to
direct hot air under the overlap,
then the two sheets are firmly
pressed together with a feed
roller. Also possible:
Repairing
PVC tarpaulins
by overlap weld-
ing with a slit nozzle.
