Welding

 Move the pipe and shaped piece quickly and axially to the mark on the heating arbour and
jack fitted on the heating element and fix them in place.
 Keep them secure for the heating time as shown in tables 2-4.
 After the elapse of the heating time, pull the pipe and shaped pipe out of the heating arbour
and jack quickly and push them together up to the mark immediately without turning them
(positioning time shown in tables 2-4).
 Hold the connection tight for the time shown in tables 2-4 and then allow it to cool.
The weld must not be stressed by further installation work until after the elapse of
the cooling time!
 After each weld the heating arbour and jack should be cleaned with non-fibrous paper and, if
necessary, methylated spirits.
