
Open the slide again with button < >, then switch off planer motor. Unlock planer take
it out of machine and put it into the heat protective box.

Remove the produced cuttings without contacting the worked surfaces.

Move pipe ends to each other with button < >.

Check pipe mismatch and gap on the joining pipe ends.
According to DVS 2207, the mismatch on the pipe outer side must not exceed 0.1 x pipe
wall thickness, the admissible gap must not exceed 0.5 mm.
The mismatch compensation is carried out via further tightening or releasing of the clamping
nuts. In case of a mismatch compensation, planing must be carried out again afterwards.

Open slide again slightly with button < >.

The adjustment pressure for the pipe dimension to be welded can be gathered from the
table. Add the movement pressure.
Set the resulting pressure value at the adjusting screw (no. 9) and check by actuating the
button <
>.

Open slide again slightly with button < >.

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 WI HEAT
®
heating element, which has been cleaned and brought to nominal
temperature, by means of the handle upwards between the pipes, if necessary wait until the
control lamp on the WI HEAT
®
heating element flashes in regular intervals.
Take care that it lies in a cut-out of the pull-off bar (chapter: 4.2.1).

Move the workpieces smoothly with the set adjustment pressure to WI HEAT
®
heating
element, therefore press button < >.
When the prescribed revolving bead height has been reached, reduce pressure. For this
purpose, release the clamping lever (14).

The heating up time starts now. Press the stop watch and compare the actual time with the
nominal time taken from the table.

After releasing the adjustment pressure tighten the clamping lever (14) again.

After expiration of the heating up time, open the slides with button < >, remove the
heating element as quickly as possible, put it into the heat protective box and move the
workpieces together shock-free with button <
>.
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 button
< > pressed for approximately 10s, so that the hydraulic accumulator can be filled.
During the cooling down period re-adjust pressure, if necessary (the pressure for cooling
down is the same as the set adjustment pressure).

After expiration of the cooling down period, release pressure therefore loosen clamping
lever (14) on.

Open the clamping rings and remove the welded part.

Afterwards open the slides with button < >.
