PHASE 1: Approach and Pre-heating
Once you are sure that the
temperature of the heating plate
is the one required, insert it in
between the ends to be welded.
Close the carriages and keep the pressure (P
1
+P
t
). Wait until the bead reaches the width (UNI 10520) or height (DVS 2207)
required (depends on the standard being used).
Slowly release the
distributor lever.
PHASE 2: Heating
Unscrew the pressure discharge
valve in a gradual manner until the
maximum pressure P
2
is reached.
P
2
is sufficient to keep the ends in
touch with the heating plate.
Close the pressure discharge
valve by rotating it in a clockwise
manner.
Wait for the t
2
time to end.
During the t
2
time, be sure that the
ends NEVER detach from the
heating plate. Should this happen,
the welding MUST be repeated from
the beginning.
