► Regularly clean the power tool's air fins.
The motor's fan will draw the dust inside the
housing and excessive accumulation of powdered
metal may cause electrical hazards.
► Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
Additional safety warnings
Wear safety goggles.
► Never use the machine with a damaged cable.
Do not touch the damaged cable and pull the
mains plug when the cable is damaged while
working.
Damaged cables increase the risk of an electric
shock.
Noise/vibration information

The various materials need different welding temperatures.
Thermoplasts like PVC or Polyolefines can be welded with
maximum temperature.
For welding Linoleum or caoutchouc materials pay atten-
tion to the manufacturers specifications.
The 4 welding nozzles (1) only heat the area of the groove.
The other parts besides the groove are not heated. You
avoid shiny stripes along the groove by that means.
Preparing the groove
The seam has to be prepared with a groove suitable to the
welding rod. The groove depth should not amount more
than 2/3 of the flooring thickness. It should not amount
more than 1.8 mm if you use a 4 mm welding rod.
Half-round blades with a radius of more than 1.8 mm might
cause reduced collateral welding. In this case you observe
small dark stripes between welding rod and flooring. De-
crease the groove depth to 1.3 mm if this happens. Surely
the durability of the groove will decrease, too.
Heating up the device (image C)
To heat up the device switch the hot-air-gun to maximum
power. See temperature display
As long as the Weldmaster does not run, the airflow is
directed sideways and not through the nozzle towards the
flooring. Thus the flooring cannot be damaged by overhea-
ting. Set the speed control with the + and - buttons.
Setting the correct speed and temperature
You have set the adequate speed and temperature, if a
little string of melted material will show at the point where
welding rod and flooring surface meets.
This indicates that the surface had melted.

If the string is getting bigger, run the Weldmaster a bit fas-
83
ter. It should be hardly visible, otherwise the welding wheel
+/- 1.5 dB
may spread it over the surface.
The following information has to be interpreted as standard
values. These values will vary on the basis of ambient
temperature, type of flooring and welding rod.
Standard values for speed and temperature
These standard values should help the user to operate the
machine. Always follow the specifications of the flooring
manufacturers.
