far as it will go to have zero pressure in the hydraulic cir-
cuit. Then push the carriage mover lever to its close-in po-
sition while simultaneously turning the maximum pressure
regulator gradually clockwise. Watch the display closely to
observe at which pressure level the carriage is "dragged" to
start moving.
The START/SET key has to be pressed when the carriage
starts moving, in order to save this drag pressure applicable
to the welding to memory.
The exact drag pressure depends on various condi-
tions (pipe size and material, position of the ma-
chine, etc.) and has to be determined for every
Important
welding individually.
4.3.3 Possibility to Change Welding Parameters
Subsequent to setting the drag pressure, Display 20 shows
on the screen, provided that manual data input is enabled
in the Reporting sub-menu of the configuration menu.
In both screens enabling manual input of welding param-
eters (Displays 20 and 21), the ï and ð cursor keys allow
moving on from digit to digit and from value to value. The
selected digit of a parameter value is changed using the ñ
and ò cursor keys. The START/SET key is used to confirm the
inputs. By pressing the START/SET key, you also make the
control unit go on to the next screen.
The parameters set manually are kept in memory
when the machine is turned off. Only the pressure
values are computed individually for every welding
Info
process. If the pipe parameters change, all param-
eters have to be set once again. The machine recog-
nizes the change of pipe parameters and brings the
operator directly to the menu for changing them.
4.3.4 Setting the Joining Pressure and Starting the Bead Build-up Stage
After butt facing and pipe alignment check, the welding
process proper starts by setting the joining pressure (i. e.,
the maximum pressure that will be reached during the pro-
cess, in the bead build-up stage and at the end of the join-
ing stage). This is done by pressing the carriage mover lever
to its close-in position and setting the maximum pressure
regulator to the level to be kept during bead build-up and
joining/cooling. The actual pressure shows (see Display 22)
and the control software moves on to the next step as soon
as the pressure is within tolerance.
The display also shows the nominal joining pressure applica-
ble to this welding. After setting the joining pressure (maxi-
mum pressure), move apart the carriage of the machine.
