Measures For Preparing Welding - Rothenberger ROWELD P 160 Saniline Instrucciones De Uso

The red "Stand by" diode on the heating element lights up, which means: voltage is being ap-
plied. Switch on the heating element on the hand grip using the large press-button (lights up
green) and set the desired temperature using the "+" or "-" button (160°C to 285°C / 320°F to
545°F).
Heating is displayed on the hand grip by the yellow diode. Horizontal bars also appear on the
temperature indicator. The yellow diode goes out shortly before reaching the set nominal tem-
perature (tolerance +/-3°C / 5.4°F) and the green one lights up. The heating element is usable
after a further 10 minutes. Note: upon first reaching the nominal temperature the set value can
be exceeded for short time.
Check the temperature using an external temperature measuring instrument. If there are devia-
tions it means that the heating element must be re-calibrated: press the "+" and "-" button simul-
taneously and then set the difference using the "+" or "-" button.
If "Er1" appears this means the electronics are defective. For "Er2" the resistance thermometer
is either defective or not connected. Send the device to an authorized ROTHENBERGER spe-
cialist workshop.
Very hot – Do not touch! The heating element can reach a temperature of approx.
290°C / 554°F!

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 clamping
inserts, or the bracket + lower reduction clamping inserts + support fork inserts, must
match!
 Open the clamping plates (8) and swing them to the rear position. Press the upper reducing
insert against the rear stop and tighten the tensioning screw (8.2).
 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 knurled head screw and move
the support bracket accordingly, turn if required and tighten knurled head screw.
For straight pipes to be welded align the support brackets with the front surface parallel to
the centre of the groove in the tables!
 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.
 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 diode goes off and the green diode lights.
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 green diode lights up (according
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 swiveled in state (work position) and swivel back again after-
wards. The operativeness of the safety switch in the trimmer 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.
