• This is followed by a steady pressure increase until the joining
pressure is reached.
• The new joint then cools down at the predefined pressure. If the
selected weldind standard requires the pressure to be reduced in
the cooling stage, the machine performs this reduction automati-
cally, in line with the provisions in the standard.
• After the cooling time is over, the machine shuts off the pressure
automatically, and the joint can be taken out of the chassis.
• If the optional tag printer is used, a tag to label the new joint
can be printed off.

Start of Operation, Switching the Machine on

Before the control unit is turned on, check the oil level of the
hydraulic and control unit and top up with HF-E 15 hydraulic
oil as needed.
Important
The surfaces of the heating element have to be free of grease
and clean, or they have to be cleaned.
Important
Make sure all connectors are tight in their sockets and note
that operation on a worksite is only acceptable if the power
supply has earth-leakage circuit breakers.
Important
Place the machine on a level surface and ensure it cannot slide. After
connecting the power supply cord to the mains power supply or a
generator, the machine is turned on at the On/Off switch.
It has to be ensured that the voltage of the power source the
machine is connected to corresponds to the rated voltage of
the machine. Also the following has to be respected when
using extension cables:
Caution
For 230 V power: wire section 2.5 mm² = max. 75 m long
After the machine was switched on, first Display 1 appears on the
screen, then a screen with the version of the used control software.
The machine will then automatically start an auto-test process (see
Display 2); this test, which includes three screens, can be canceled by
pressing the STOP/RESET key.
If the input voltage is not within tolerance, from approx.
160 V to approx. 300 V, the machine switches itself off for
protection. This protective feature is provided by a switch
Important
and will not result in an excess or insufficient voltage error
line (see Sect. 4.8).
If the machine is not in the "open" position (i.e., movable carriage as
far apart from the fixed one as possible), Display 3 shows. To move
it, press the OPEN key. The machine will then move it to the far end.
After that, Display 4 shows, with the data of the next welding, includ-
ing time of day, date, report number, and joint number, along with — in
the second-to-last line — the actual input voltage and the actual and
nominal heating element temperature before and after the slash.
