2. Heat
Simultaneously insert the tube and the connection up to
the * mark on their respective sockets, holding both
perpendicular to the heating bar of the Welding machine.
At this point the minimum heating times should be taken
(see table 1).
* Before cutting, mark the end of
the tube according to the
insertion measurements for each
diameter. (see table 2).
3. Join
When the heating times have been met, immediately
remove the tube and connection and insert the tip of the
tube into the connection **.
Suggestion:
Let each Thermofusion stand
without subjecting it to significant
efforts until it cools completely.
** Stop inserting the tube when
the two visible rings that are
formed by grinding the material
have joined. Once the thrust is suspended, there is the
possibility, for 4 seconds, to straighten the connection or
rotate it a maximum of 15 degrees.

No leakage
Total security in the joints. Termoflow Foset® guarantees
that there are no leaks since it perfectly joins the tube
and the connection, turning the pipe into a single
indissoluble piece, thanks to its
Thermofusion system.
Complying with the previous steps guarantees the
success of this process.
Table 1 shows the heating times in the Hot Melt for each
pipe diameter, the maximum coupling intervals and the
cooling times. It is important to note that the heating
time begins to be measured when the tube and
connection entered the corresponding sockets and
pressure was finished on them.
When working at a temperature below 50 ºF or in the
presence of wind, it is recommended to increase the
heating times by 50%, in order to achieve a safe
Thermofusion.
