 Switch off heating plate.
 Remove trimmer unit, heating plate and hydraulic unit mains plugs from power outlet and roll
 Disconnect and roll up hydraulic hoses.
3.3
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
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]
Welding factors (SF): PE = 0,15 N/mm², PP = 0,10 N/mm², PVDF = 0,10 N/mm²
(ROWELD P 160/5 B: the total cylinder surface is 3.53 cm²)
(ROWELD P 250/8 B: the total cylinder surface is 6.26 cm²)
(ROWELD P 355/12 B: the total cylinder surface is 6.26 cm²)
(ROWELD P 500/18 B and P 630/24 B: the total cylinder surface is 14.13 cm²)
(ROWELD P 630/24 B Plus: the total cylinder surface is 22.38 cm²)

Care and maintenance

To ensure that the welding machine functions properly, observe the following maintenance
recommendations:
• The guide rods must be kept free of dirt and grime. Replace guide rods whenever surface
• Trimmer unit, heating plate, hydraulic unit may only be supplied with the voltage specified on
• To achieve perfect welding results, it is essential to keep the heating plate clean. If the surface

Putting out of operation

Let the heating element cool or stow it in such a way that no adjacent materials
can be ignited!
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!
Important! Protect couplings from damage and dirt!
