needed during welding on the screen to the welder's attention or has
him confirm them, and which makes a report of the welding operation.
No welding report is generated when the welding is fully manual.
Below, this booklet first presents the welding process in the WeldCon-
trol Mode. How welding is performed in the Manual Mode is explained
in Section 4.4.
If the machine is set to Manual Mode (fully manual welding
process without data logging/report generation), the opera-
tor can switch it to WeldControl Mode by pressing the ï and
ð arrow keys simultaneously.

chassis. Use the appropriate reducer inserts if the compo-
nent size is smaller than the basic machine chassis. When the
fourth clamp of the machine is removed, tees and elbows can
be processed. Then, to launch the welding process, press the
START/SET key.
After all traceability data enabled in the configuration menu were
entered, the parameters of the pipes to be welded have to be entered.
If pipe parameters of an earlier welding are available and no code
error was detected, all welding parameters of the previous welding
are proposed and can be confirmed in one go (see Display 16).
From this display, it is possible to change the pipe parameters by
pressing the STOP/RESET key. Then the first thing is to select the pipe
material in a list; use the ñ and ò cursor keys and confirm by pressing
the START/SET key (see Display 14). Then the alphanumeric keypad
(see the first info in Sect. 4.1) allows entering the diameter and the
wall thickness, both confirmed by the START/SET key (see Display 15).
Instead of the wall thickness, you may want to enter the Standard
Dimension Ratio (SDR); then display this input line instead of the wall
thickness line by pressing the ï and ð simultaneously and enter the
SDR value. The machine then displays the whole set of parameters as
an overview. In case there are errors, it is possible either to enter all
data once more by pressing the STOP/RESET key, or to return to the
previous step by pressing ñ and correct the data one at a time.
If pipe codes were entered previously in the traceability data for the
joint, the machine automatically presents the welding parameters
contained in the pipe codes for confirmation.
4.3.1 Facing the Pipe Butts
To ensure that the pipe butts are level, insert the pipe facing tool be-
tween the machine carriages and turn it on. Using the carriage mover
lever on the hydraulic unit, have the movable carriage close in toward
the center in order to bring the pipes into contact with the facing tool.
Use the pressure regulator to adjust the pressure manually, if needed,
while the facing tool is trimming the pipes.
The farther the carriage mover lever is pushed to the left,
the faster the carriage closes in and the faster pressure in-
creases. The farther it is pushed to the right, the faster the
carriage of the machine moves apart, and the faster pressure

decreases.
Pipe facing should continue until shaving forms a continuous blade
that rolls twice or three times around the pipe ends, so the butts are
