Putting Out Of Operation; General Requirements - Rothenberger ROWELD P160-630B/Plus Instrucciones De Uso

3.2.4

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!
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]
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)
4 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
shows signs of erosion or damage, otherwise hydraulic system may loose pressure.
• Trimmer unit, heating plate, hydraulic unit may only be supplied with the voltage specified on
the type plates.
• To achieve perfect welding results, it is essential to keep the heating plate clean. If the surface
is damaged or shows signs of erosion, the surface must be recoated or replaced. Material
residues on the heating plate surface reduces the non-sticking properties of the coating.
Remove all residues with non-linting paper and alcohol (heating plate must be cool!).
