Welding - Rothenberger ROWELD P160-630B Plus Professional Bedienungsanleitung

Stay a safe distance away from the machine. Do not stand or reach into the ma-
chine. Keep other people away from the work area!
 Check to ensure that the heating plate has reached the setpoint operating temperature.
CAUTION! To guarantee uniform heat distribution over the entire heating element, the
heating element must not be used until at least 10 minutes after it reaches the target
temperature. Check and verify the temperature with a temperature meter and readjust if
necessary!
 Position the electrical trimmer between the two workpieces.
P500-630B Plus: Verify the direction of rotation! The machines were polarized to turn
clockwise before leaving our factory!
 Switch on trimmer unit. The planing discs should turn in the cutting direction; if not, use suit-
able tools to change over the phase inverter in the mains plug.
Risk of serious injury! During operation trimmer unit, stay a safe distance away
from the machine, and do not reach into the rotating knife. Use trimmer in working
position only and return it into the designated carrying frame immediately after use.
Ensure that the safety switch functions properly at all times to avoid any accidental
starting of the trimmer away from the basic machine.
 Turn the pressure adjustment valve counter-clockwise all the way.
 Press the control lever leftward and slowly increase the milling pressure to the optimal value.
An excessively high milling pressure can lead to overheating and damage to the
miller drive. When the milling drive is overloaded or at rest, raise the machine and
reduce the pressure!
 Once shavings with a thickness of < = 0.2mm are steadily exiting the milling machine, press
the control lever rightward and guide the machine apart.
 Turn off the milling equipment, and wait for the planing disks to stop. Remove the milling
equipment from the basic machine, and place it in the storage case.
 Bring the work pieces together, and let up on the pressure by opening the pressure release
valve.
 Check to see that the welding surfaces are flat, parallel and axially aligned.
Should the joint surfaces show any misalignment, repeat the trimming procedure. For best re-
sults the workpiece ends should not be mismatched by more than 10% of the wall thickness and
the maximum gap between the joint surfaces no more than 0.5 mm. This recommendation does
not release you from your obligation to observe national welding guidelines. Clear away any
remaining shavings with a clean brush.
CAUTION! Do not touch the trimmed, ready to weld surfaces. Ensure that the surfaces
are free of any and all containments and foreign objects!

Welding

Risk of injury! Keep a safe distance from the machine when mechanically closing
clamps and moving workpieces. Keep hands, limbs and objects such as clothing,
tools etc. away from running machine!
 While moving workpiece ends to welding position, read the workpiece drag pressure from
the manometer on the hydraulic unit.
The workpiece drag pressure is the minimum amount of pressure required to set the workpiece
– depending on weight and length – in axial motion. This value must be precisely determined; it
will be necessary to engage and disengage the machine and workpieces several times and to
set the pressure adjustment valve until the machine almost comes to a standstill. Add the drag
pressure to the conformation, heat-penetration and joint pressure.
 Insert the heating plate into the basic unit between the two workpiece ends and make sure
that the heating plate's supports are seated in the notches on the take-off device.
