Example applications (see figures A–F)
Images of example applications can be found on the graphics pages.
The distance between the nozzle and the workpiece depends on the material you are working on (metal, plastic etc.) and the intended working method.
The optimum temperature for each application can be determined by a practical test.
Always test the amount of air and temperature first. Start at a greater distance and a lower power setting. Then adjust the distance and power setting according to requirements.
If you are unsure what material you are working on or what effect the hot air might have on it, first test the effect on a concealed area.
All example applications apart from "Stripping paint from window frames" can be carried out without the use of accessories. However, using the recommended accessories will simplify the work and considerably increase the quality of the result.
- Take care when changing the nozzle. Do not touch the nozzle while it is hot. Let the heat gun cool down and wear protective gloves during changeover. The heat from the nozzle can cause burns.
Removing varnish/loosening adhesives (see figure A)
Fit the surface nozzle (5) (accessory). Briefly soften the varnish with hot air and remove it with a clean spatula. Long heat exposure burns the varnish and makes removal more difficult.
Many adhesives can be softened using heat. By heating adhesives, you can break connections or remove excess adhesive.
Stripping paint from window frames (see figure B)
- The glass protection nozzle (6) (accessory) must be used for this application. There is a risk that the glass may break.
You can remove the paint from profiled surfaces with a suitable spatula and brush it off with a soft wire brush.
Thawing frozen water pipes (see figure C)
- Before applying heat to the pipe, check it is in fact a water pipe. Water pipes and gas pipes often look identical from the outside. Gas pipes must under no circumstances be heated.
Fit the angle nozzle (7) (accessory). Gradually heat the frozen points of the pipe, starting at the outlet and moving back towards the inlet.
Take great care when warming plastic pipes and pipe connections to avoid causing damage.
Shaping plastic pipes (see figure D)
Fit the reflector nozzle (8) (accessory). Fill plastic pipes with sand and seal them on both sides to prevent the pipe bending. Carefully and evenly heat the pipe by moving the tool back and forth from one side to the other.
Soft Soldering (see figure E)
For spot welding, fit the reducing nozzle (9); for welding pipes, fit the reflector nozzle (8) (both accessories).
If you are using solder without flux, apply soldering grease or paste to the solder joint. Heat the solder joint and apply the solder. The solder must be melted by the temperature of the workpiece.
If necessary, remove the flux after the solder joint has cooled down.
Heat-shrinking (see figure F)
Fit the reflector nozzle (8) (accessory). Choose the diameter of the heat shrink plastic tube (10) (accessory) suitable for the workpiece. Evenly heat the heat shrink plastic tube until it fits closely against the workpiece.
