•
Check sheet displacement and crack at the ends of the nudging sheets. According to
DVS 2207 the displacement of the tolerated crack may not be larger than 0,5 mm.
- The displacement compensation is realized by opening the clamping nuts and displacing
of the sheets. Afterwards refasten the clamping nuts.
•
Take the adjusting force for the sheet dimensions to be welded out of the table.
•
Heating up time, max. change-over time, cooling-down time and height of bead for the
sheet dimensions to be welded have to be taken out of the table.
•
Drive the slide a little bit open.
•
Slew in the cleaned heating element when it has reached the desired temperature. If
necessary wait until the control lamp smoothly blinks.
•
Drive the slides with identified adjusting force and hitchless together. The reached force can
be seen on the force range (6) of the slide of the left side.
Having reached the mandatory surrounding bead height reduce the force
(heating up force = appr. 10 % of adjusting force).
•
Now the heating up time begins. Press the stopwatch and compare the actual time with the
desired time of the table.
•
Having finished the heating up time drive the slide a little bit open, slew out the heating
element as fast as possible and drive the slides hitchless together.
The maximum time for this process is given by the value for the change-over time indicated
in the table.
•
After the erection of the welding force press the stopwatch. During the cooling down adjust
the force if necessary once again (the cooling down force is the same as the adjusting
force).
•
After the cooling down time has elapsed remove the force.
•
Remove the clamping nuts and clamping beams and take out the welded piece.
•
Then drive the slides open.
