Operating instructions
In accordance with national or EU ordinances and guidelines, e. g. DVS 2212,
Section I, only duly qualified and authorised personnel are allowed to operate the
ROWELD welding machines!
Only trained and authorised welders are allowed to operate the machine!
3.2.1
Putting into operation
Please read through the operating instructions and safety instructions atten-
tively before you put the butt fusion welding machine into operation!
Do not use the heating element in explosive environments or bring it into
contact with easily flammable materials!
Either fasten the basic unit on a workbench by using the included screws or fasten it by us-
ing an existing vice.
Fasten the table clamp on the workbench and put the heating element in it.
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 (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 authorised ROTHENBERGER speci-
alist workshop.
Very hot – Do not touch! The heating element can reach a temperature of
approx. 290°C / 554°F!

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.
