Putting Out Of Operation; General Requirements; Important Information On Welding Parameters - Rothenberger ROWELD P160-630B Plus Professional Bedienungsanleitung

 Engage the machine, set and maintain the required conformation pressure plus drag pres-
sure.
 As soon as sufficient bead has formed around the entire circumference of the workpiece
ends, slowly release the pressure by slowly opening the relief valve.
 Set the pressure so that workpiece ends have uniform almost pressureless contact to the
heating plate (warm up).
 Now close the relief valve. Ensure that the workpiece ends still have contact with the heating
plate.
 After the warm-up phase, disengage workpieces, remove the heating plate and re-engage
the workpieces. Increase the pressure linear to the respective joint pressure and maintain
that pressure until the joint is fully cooled.
 Regularly check the pressure and pump it back up when necessary. If the pressure loss is
excessive, have the hydraulic system checked.
CAUTION: Press and hold the control lever for the first 20 to 100 seconds then release
(neutral switch position).
 Put the heating element back into the storage case.
 After the joint has fully cooled, slowly release the pressure by opening the relief valve, un-
clamp the workpieces and remove from the machine.
 Disengage the basic unit, write protocol. The machine is now ready for the next welding cy-
cle.
All welding parameters can be found in the enclosed welding tables.

Putting out of operation

 Switch off heating plate.
Let the heating element cool or stow it in such a way that no adjacent materials can
be ignited!
 Remove trimmer unit, heating plate and hydraulic unit mains plugs from power outlet and roll
up cables.
Transport and set the hydraulic unit only in a horizontal position. If it is set at an
angle, oil escapes from the vented plugs with the dipstick!
 Disconnect and roll up hydraulic hoses.
Important! Protect couplings from damage and dirt!

General requirements

As weather and ambient conditions can seriously effect welding procedures and joints, it is es-
sential to duly observe national welding guidelines and ordinances, e. g. DVS Guideline 2207,
Sections 1, 11 and 15.
Welding requires continuous and due supervision and monitoring!

Important information on welding parameters

For welding parameters such as temperature, pressure and time, consult your national welding
guidelines and ordinances, e. g. DVS Guideline 2207, Sections 1, 11 and 15.
