Preparing for welding
To carry out welding correctly, ALL the following steps must be implemented:
1.
Cut the pipe at right angles with
the special nippers.
2.
Scrape
homogeneously down to at least 1
cm (0.39 in) in excess of the pipe
inserting length in the fitting by
using the scraper.
3.
Mark the welding length on the pipe
(length equal to half the coupler
length) with the special marker pen.
4
.
Remove any mud, dust, grease or
other traces of dirt from the pipe
ends and the fitting inside.
5.
Lock the pipes with the special
aligner after inserting the fitting and
keep them locked throughout the
welding cycle and the subsequent
cooling time.
6.
It is now possible to weld the fitting
on the pipes, by inserting the
cables with connectors in the fitting
turns and checking the welding time
and voltage.
