Exchanging the reduction Inserts
Unscrew the mounted reduction inserts by means of the provided Allan key.
Screw the reduction inserts with the corresponding diameter into the clamping devices.
When welding bends, the angle can be set on the basic clamping devices (on each side
between -15° to +15°).
If necessary (e.g. for T-pieces) a special basic clamping device can be provided by means
of which very short sections can be clamped.

Do wear safety gloves as protection against burning.
A stop-watch must be available for recording the actual times for heating up and cooling.
A welding table must be available from which the parameters for the pipe dimensions to be
welded prescribed by the welding prescriptions may be taken.
The heating element surfaces must be clean and especially non greasy. Therefore they
need to be cleaned shortly before each welding or in case of dirtiness by means of a
fibre-
free paper
and a cleaning agent (e.g. PE cleaner or WIDOS pipe cleaning tissues).
The anti-adhesive coating of the heating element must remain undamaged in the working
area.
