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
(ROWELD P 315 W the total cylinder surface is 8,04 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.
• The machine 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).
• Before every start-up, check the oil level of the hydraulic unit (oil level should lie between full
and empty marks). Replenish hydraulic oil whenever necessary (HLP – 46, no.: 53649).
• Change hydraulic oil (HLP – 46, no.: 53649) every twelve months.
• To avoid malfunctions, regularly check the hydraulic unit for leaks, proper fit of connections
of damage or wear.
• Regrease the linear guides every 6-months. The linear guide lubricating circuit must be filled
with lithium-based lubricating grease. This grease has an extremely pressure resistant additive
in it. This is a top quality lubricating grease, however, the quality deteriorates over time.
• New lubricating grease is squirted in through the lubricating nipple mounted on the front of
the wagon. We recommend that you use a top quality lithium-based lubricating grease.
• The trimmer unit is equipped with bi-directional blades. Rotate or replace blades whenever
trimming performance is no longer up to expectations.
