• After the heating time, they are removed from the
heating element and it is removed from in-between
them.
• The plasticized component butt is then pushed into
the jointing fitting, the inside surface of which has
also plasticized, and no external forces must be ap-
plied prior to their having completely cooled down.

Preparing the Welding Process

Install the proper spigot and socket for the diameter of
the component and the jointing fitting on the heating
element. If they are not in place yet, install the clamp
jaws that match the diameter of the component and the
fitting on the machine carriages. The hex keys needed for
both operations are supplied with the machine.
The socket welding machine is designed exclu-
sively for use with the heating spigots and sock-
ets included in the technical description of the
Important
machine. The use of any other heating spigot or
socket puts the welding operation at risk of yield-
ing a poor outcome and will in all cases dispense
the manufacturer from assuming any liability or
responsibility for the product.
The required clamps are composed of three pairs. Two
pairs will be fitted to the carriage on the pipe side of the
machine, i. e. the right-hand side when standing in front
of it, where the length of pipe will be clamped.
One pair will be installed on the fitting side of
the machine, i. e. the left-hand carriage, when
standing in front of the machine, with the bar
securing the fitting where this pipeline joiner
will be clamped.
Components will be secured in clearances ma-
chined in both clamps of a pair which, together,
form a diamond or rhombus shape suitable for
various component diameters. Be sure that all
three clamp pairs form a diamond of the same
size on the inside. On the fitting-side carriage,
install those clamps of which the edge pointing
to the midline of the machine is machined as a
low, flange-like bead against which the fitting
will be positioned (see figure on the right for
reference, which also shows the adjustable bar
that secures the fitting during the welding op-
