• Open slide again, switch off the planer, remove it and put it into the heat protective box.

Remove the produced cuttings, thereby preventing contact with the worked surfaces.

• Close slide again.

• Check pipe mismatch and gap at the abutting pipe ends.

According to DVS 2207, the mismatch on the pipe outside should not exceed 0.1 x pipe wall

thickness, the admissible gap should not exceed 0.5 mm.

The mismatch compensation is effected through the stronger tightening or releasing of the

clamping nuts. In case mismatch compensation was effected, renewed planing has to be

carried out afterwards.

• Take the adjustment force for the pipe dimension to be welded from the table and add the

motivity.

• Open slide again somewhat.

• Take the heating-up time, the maximum change-over time, the cooling-down time and The

bead height for the pipe dimension to be welded from the table.

• Bring the heating element which has been cleaned and brought to its nominal temperature

between the pipes with the handle facing downwards (hang into guide bar).

• Close the slide smoothly with the determined adjustment force.

The force applied can be gathered from the force scale on the handwheel. When the

prescribed circulating bead height has been reached, reduce the force (heating up pressure =

approx. 10 % of the adjustment pressure).

• Now the heating up time starts. 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 slide, remove heating element as quickly as

possible, put it into the heat protective box and close the slide smoothly. The maximum time

limit for this purpose is predetermined by the value for the change-Over time taken from the

table.

• Press the stop-watch when the welding pressure has been built up.

If necessary, readjust the pressure during cooling down (the pressure for cooling down is the

same as the adjustment pressure).

• After expiration of the cooling-down period stop the pressure, remove the welded parts and

open the slide.
