ROTHENBERGER ROWELD P 160 SANILINE - Manual (Page 16)

14 ENGLISH
If the heater element displays a smaller value than that on the external temperature measuring
instrument then the difference must be adjusted using the “+“ button. For indicated values in the
other direction adjust the difference using the “-“ button. If “Er1“ appears it means that the elec-
tronics are defective. “Er2“ means that the resistance thermometer is defective or not connected.
Very hot
– Do not touch! The heating element can reach a temperature of
approx. 290°C!
3.2.2 Measures for preparing welding
 For pipes which are smaller than the maximum diameter of 160 mm to be welded the clamp-
ing inserts / bracket of the corresponding diameter are to be inserted in the main clamps.
Be sure to use the correct reduction clamping inserts! The upper reduction clamp-
ing inserts, or the bracket + lower reduction clamping inserts + support fork in-
serts, must match!
 Version A: Open the clamping plates (8) and swing them to the rear position. Press the up-
per reducing insert against the rear stop and tighten the tensioning screw (8.2).
 Version B: Open the clamping plates (9) and insert the upper clamping element (9.1) and
tip forward (the clamping pin is the rotation axis).
 Insert the lower reduction.
 Supports bracket inserts are to be inserted in the support brackets (10) and fastened with
the knurled screws.
 Insert the plastic pipes or fittings to be welded into the clamps.
 Put the support brackets (10) under the pipe or fitting, loosen hexagonal screw with multi-
purpose spanner SW 17, and move the support bracket accordingly and turn if required.
For straight pipes to be welded align the support brackets with the front surface
parallel to the centre of the groove in the tables!
 Version A: Close the clamping plates (8). Using the adjusting nut (8.1) adjust the tension
and bring the handle to the end position until the maximum force is reached.
 Version B: Untwist the clamping plates (9), swing the bracket backward and bring the
clamping device to the operating position. When tensioning, be sure that the wings of the
wing nut are always at 90° to the axis of the pipe.
 Check whether the workpieces are tight in the clamping tool by moving the workpieces to-
gether. When applied max. welding pressure must not slip through pipes! Thus, a successful
welding process it is ensured.
 Also check whether the heating element has reached operating temperature. Heating is
ended when the yellow pilot lamp on the temperature regulator flashes.
To guarantee even distribution of heat over the entire surface of the heating plate,
it is required to wait a period of approx. 10 minutes after the lamp flashes (accord-
ing to DVS). You must check the temperature with an appropriate temperature
measurement device!
 Swing the trimmer (1) between the pieces of pipe until the ratchet pawl (7) snaps in and turn
on with the handle.
Risk of injury! Do not grasp into the running knife while the trimmer is put into
operation. Operate trimmer only in swivelled in state (work position) and swiv-
el back again afterwards. The operativeness of the safety switch in the trim-
mer must be guaranteed at all times to prevent unintentional starting outside
the work position!
 With the grip bar (6) move the ends of the workpieces carefully against the rotating knives of
the trimmer disks.
An excessively high milling pressure can lead to overheating and damage to
the miller drive. When the milling drive is overloaded or at rest, raise the ma-
chine and reduce the pressure!
