Take heating up time, maximum change-over time, cooling down time and bead height for the pipe
dimension to be welded from the table.
Move the heating element, which has been cleaned and brought to nominal temperature, by means of the
handle upwards between the pipes.
Move pipes to heating element smoothly to the set adjustment pressure with <valve lever> on:
“forwards”.
When the prescribed revolving bead height has been reached, reduce pressure. For this purpose, move
the valve lever to <Pressure release> until heating up pressure has built up has reduced almost to zero
(≤ 0,01 N/mm²).
The heating up time starts now. Press the stop watch and compare the actual time with the nominal time
taken from the table.
After expiration of the heating up time, open the slide, with <valve lever> on: “backwards” remove the
heating element as quickly as possible, put it into the protective box and close the slide smoothly with
<valve lever> on: “forwards”.
The maximum time frame for this process is predetermined by the value for the change-over time taken
from the table.
When the welding pressure has been built up, press the stop-watch and keep the <valve lever> for
approximately 10s on the position “forwards” so that the hydraulic accumulator can be filled. During the
cooling down period re-adjust pressure, if necessary (cooling pressure = adjustment pressure).
After expiration of the cooling down period, release pressure with <valve lever> on: “Pressure release”.
Do not open basic machine!
Open the clamping rings and remove the welded part.
Open the slide with <valve lever> on: “backwards”.

Take care that it lies in the zone of the diminution of the
puller, if required displace the shaft!
