This report file should be processed using the ROTHENBERGER Dataline 2 software and a
computer.
All welding parameters can be found in the enclosed welding tables.
3.2.4 Putting out of operation
 Use the button (6) to turn off the hydraulic unit.
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!
3.3 General requirements
As weather and ambient conditions can seriously effect welding procedures and joints, it is
essential 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!)
3.4 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.

In the event of doubt, consult the pipe manufacturer for material-specific welding parameters.
The welding parameters specified in the welding tables are strictly reference values.
ROTHENBERGER cannot assume any liability for their accuracy or completeness!
The compensation and joint pressure values specified in the welding tables were calculated using
the following formula:
pressure P [bar] = welding surface A [mm²] x welding factor SF [N/mm²]
surface of cylinder Az [cm²] x 10
Welding factors (SF): PE = 0,15 N/mm², PP = 0,10 N/mm², PVDF = 0,10 N/mm²
