
Switch on the heating element and adjust the required welding temperature (chapter: 5.6)

Screw in the reduction inserts according to the outside diameter of the pipes to be welded.

Put the workpieces into the clamping tools, tighten the clamping nuts tightly and align the workpieces
with respect to one another.
In case of long pipe ends, use WIDOS rollerstands for alignment.

Close the slide, with <valve lever> on: “forwards”, thereby reading the movement pressure on the
pressure gauge.
The movement pressure is displayed exactly when the slide with the clamped-pipe passes over into its
movement.

Subsequently, open slide again such that the planer fits in-between, with <valve lever> on: “backwards”.

Put the planer between the workpiece ends and let the locking snap in.
Noise exceeding 80 dB (A) may occur; during planing it is obligatory to wear ear protection!
There is the danger that the planer draws in clothes!
Do not hold the planer on its front sides in any case.
If the planing pressure is too high, there is the danger that the planer will get stuck during
planing. If necessary hold tight to the planer.
In case there are too many chips stop planer and remove them.
Necessarily take care that no chips will be drawn-in between the planer discs!

Move the pipe ends towards one another with <valve lever> on: “forwards” and plane same with a
planing pressure between 1 and 15 bar above the movement pressure.
Planing must be carried out until a revolving cutting has been formed on both sides.

Open the slide again with <valve lever> on: “backwards”, switch off planer motor.

Unlock planer, remove it and put it into the protective box.

Remove the produced cuttings without contacting the worked surfaces.

Close the slide with <valve lever> on: “forwards”.

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 for pipes ≤ 355 mm and 1,0 mm for pipes with 400…< 630 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.

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 pressure limiter valve and check by actuating the valve lever.

Open slide again slightly with <valve lever> on: “backwards”.
