welded have to be attached, as described in Sect- 3.4, to
the clamps of the chassis using the provided bolts.
• In the manual mode, applicable welding times and
pressures are looked up in the overview tables in the
appendix.
• In the Weld Control mode, the mandatory and the op-
tional component traceability data are entered in the
menus on the screen.
• Pipe butts are worked using the pipe facing tool.
• Pipe alignment is checked.
• The drag pressure, i.e. the minimum pressure to set the
carriage in motion and "drag" it along, is recorded at
the machine.
• The pressures relevant to the welding operation are set.
• The heating element is inserted after cleaning it and
checking its temperature.
• The welding process proper is performed (see section 4),
and the operator waits for the jointed components to
cool down.
• After the cooling time is over, pressure is shut off from
the pipes (in the manual mode by the welder, in the
Weld Control mode automatically by the machine) and
the joint can be taken out of the chassis.
4 Operation
To operate the welding system, be sure that it is set
on a proper, level surface and that power supply-
side fuse protection is as described in Sect. 3.4.
Important
Before the system 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 prohibited
if the power supply does not have earth-leakage cir-
Important
cuit breakers.
After connecting the power supply cord to the mains power
supply or a generator, turn the machine 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, when using

extension cables, their section has to comply with
the indication given in Sect. 3.4.
