• 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 pipes to cool down.
• After the cooling time is over, pressure can be shut off from the
pipes (in the manual mode by the welder, in the WeldControl
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 protection is 16 A
(slow blow).
Important
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.
The surfaces of the heating element have
to be free of grease and clean, or they
Important
have to be cleaned.
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
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 the following has to be respected when
using extension cables:
Caution
For 230 V power: wire section 1.5 mm² = max. 20 m long
4.1 Configuring the Machine, Entering Welding Parameters
After the machine was switched on, Display 1 shows on the screen.
The machine will then automatically start the auto-test process to
check the sensors and the system clock and to determine the number
of free welding reports. This test can be bypassed by holding down
the STOP/RESET key when Display 1 is showing.
If during the auto-test an error is detected, a "System Error"
message shows on the display. When this happens, the weld-
ing unit has to be disconnected immediately from the power
suppy and the fitting or heating element/facing tool, and it

has to be returned to the manufacturer for repair.
