supply is within a 10% of the specified one “ Warning Heating Mirror tart to warm up ! “
d) Select the correct temperature on the heating mirror
e) In case fit the inserts of the diameter to be welded into the machine
3.3 Pipe po itioning into the machine and facing operation
a) Open the movable trolley of the machine by means of acting the lever A (hyd. Unit) and take
it in position A2
b) Position the pipes into the machine taking care to leave enough space for the facing tool inserting
c) Check the pipes alignment, in case adjust it by means of tighten or loosing the clamps bolts.
The maximum misalignment could be lesser than 10% of the pipe or fittings wall thickness.
In any case the misalignment cannot be over than 2mm.
d) Clean the pipe ends
e) Fit in the facing tool between the two pipe's ends to be faced, by means of connecting the facing
tool into the special supports. Connect the safety pin and start the facing tool engine
f) On the facing tool there is a facer stopper (see the figure aside). In case of one of the pipe ends
has a small projection; the facer stopper let you select the only pipe to face. Put the facer stopper in
the left or in the right hole to prevent the right or left facing. To face all the pipes put the facer stopper
in the central hole.
Warning!!!: Alway check that the peed elector of the drill engine i in po ition 1 (lower peed)
g) Slowly approach the pipes ends towards the facing tool by means of acting on the hydraulic control unit (lever A Table V ) keeping
a value of pressure allowing the facing of the surfaces and avoiding an overload of the drill engine (a too much high pressure could
burnt out the drill engine). When shavings from both sides will appear continuous and homogeneous , the facing operation is
completed.
h) Put in contact the two pipes ends to be welded and check if the eventual disjunction is within the values of the following table:
In case the above values cannot be fulfilled the facing operation must be repeat.
3.4 Inertial pre ure mea urement
Before begin a welding cycle it is necessary to measure the inertial pressure. This value must be added to the pressure value shown in our
welding tables. The inertial pressure value depends on welding operating conditions (ex.: length and weight of the pipe to drag, general
condition of the machine, ambient temperature, etc.). To measure the inertial pressure follow these steps:
a) Completely open the movable trolley of the machine by means of acting the lever A and take it in position A2
b) By turning the lever F (Hyd. Unit) anticlockwise bring the pressure to zero, checking the pressure gauge
c) Turn clockwise the lever E (Hyd. Unit) until closing
d) Bring the lever A (Hyd. Unit) into position A3 (the trolleys do not move because there is no pressure)
e) By turning clockwise the hand wheel F note the inertial pressure value ( value of pressure need in order to allow the trolley moving ) by
reading it into the pressure gauge
