 Be careful when changing the nozzle! Do not touch the
hot nozzle. Allow the power tool to cool down and wear
protective gloves while changing the nozzle. Danger of
burning oneself on the hot nozzle.
Removing Varnish/Softening Adhesives (see figure A)
Mount the wide jet nozzle 8 (accessory). Briefly soften the
varnish applying hot air and remove it using a sharp, clean
scraper or putty knife. Applying heat too long will burn the var-
nish, making it more difficult to remove.
Many adhesives (e.g. of stickers) become soft when heated.
Heated adhesives allow for bonds to be separated or exces-
sive adhesive to be removed.
Removing Varnish/Paint from Windows (see figure B)
 Use of the glass protection nozzle 9 (accessory) is es-
sential. Danger of glass breaking.
On profiled surfaces, varnish can be removed using an appro-
priately fitting spatula and brushed off with a soft wire brush.
Shaping Plastic Tubing (see figure C)
Mount the reflector nozzle 10 (accessory). To avoid kinking of
the tubing, fill the tubing with sand and plug both ends. Heat
the tubing evenly by by applying the heat from side to side.
Welding Plastics (see figure D) (PHG 630 DCE)
Mount the reduction nozzle 13 and the welding shoe 12 (both
accessories). The workpieces to be welded and the welding
rod 11 (accessory) must be of the same material (e.g. both of
PVC). The seam must be clean and grease-free.
Carefully heat up the seam location until it becomes doughy.
Please note that the temperature difference between the
doughy and liquid state of plastic is low.
Feed in the welding rod 11 and allow it to run into the gap so
that a uniform bead is produced.
Shrinking (see figure E)
Mount the reduction nozzle 13 (accessory). Select the diam-
eter of the heat-shrinkable sleeve 14 (accessory) according
to the workpiece (e.g. a cable lug). Heat the heat-shrinkable
sleeve evenly.
Defrosting Water Pipes (see figure F)
 Before heating pipes, check to make sure that it is actu-
ally a water pipe. Water lines often do not differ in appear-
ance from gas lines. Gas lines are not to be heated under
any circumstances.
Place on the angle nozzle 15 (accessory). Heat the frozen
zone always from the outside to the middle.
Heat up plastic pipes as well as connections between pipe
pieces especially careful to prevent damage.
Soft Soldering (see figure G)
For point soldering, place on the reduction nozzle 13, for the
soldering of pipes/tubing, place on the reflector nozzle 10
(both accessories).
If solder without flux is used, apply soldering grease or paste
to the location to be soldered. Warm the location to be sol-
dered for 50–120 seconds depending on the material. Apply
the solder. The solder must melt from the workpiece temper-
ature. After the soldered location has cooled, remove the flux.
