Connect power plug to the power supply stated on the type plate.
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 (tol/-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 authorised ROTHENBERGER speci-
alist workshop.
Very hot – Do not touch! The heating element can reach a temperature of
approx. 290°C / 554°F!
3.2.2 Measures for preparing welding
For Pipe-to-Pipe welding the two wide main clamps are remaining in the machine.
For Pip-to-Fitting welding the left hand side wide main clamp has to be changed against small
Fitting main clamp.
For Fitting-to-Fitting welding both wide main clamps have to be changed against small fitting
main clamps.
The right hand side small fitting main clamp is available as an option (art. No. 55809).

Loosen winged handle at main clamp set and swivel away to the front. Then move upper
main clamps up and backwards.

For pipes which are smaller than the maximum diameter of 110 mm insert reduction clamp-
ing inserts and fix them by using the knurled screw.

Insert the plastic pipes or fittings to be welded into the clamps. Close upper clamps swivel in
winged handle, align pipe or fitting and screw up the winged handle tightly.

Check whether the workpieces are tight in the clamping tool by moving the workpieces to-
gether.

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 tempera-
ture measurement device!

Place the trimmer between the pipe sections to be welded and fix it by the swivel.

With the hand wheel move the pipe ends carefully against the trimmer blades of the trimmer
discs and turn the trimmer around by moving the handle up and down.
Pipes and fittings can be machined on one side only by turning the block screws on the front
bottom side of the machine towards the side, which is not to be machined.
Risk of injury! Do not grasp into the running knife while the trimmer is put into
operation!

After the front sides are trimmed flat, which can be recognized by an uniform and unbroken
chip, slowly move the pipe ends apart. Unlock the trimmer by the swivel and remove it.

Move workpieces together and check whether the welded surfaces are flat. If this is not the
case, trimming must be repeated.
