5.4 Trimming<br />
The pipe sections for trimming must be clamped to basic unit (cf. 4.1.3 Set up). Mount trimmer<br />
and switch on. Ensure that the trimmer is sits firmly.<br />
Trimming<br />
---------------------<br />
Use trimmer<br />
Start operation<br />
with OK<br />
---------------------<br />
Pressing the OK button activates the trimming procedure, i.e. the trimmer starts and the basic<br />
unit closes with the programmed pressure. If the clamping pressure is insufficient, use the<br />
joystick in adjust: move joystick to the left and reduce the pressure, move to the right to<br />
increase the pressure.<br />
Press the OK button to end the trimming procedure: the clamping pressure drops to minimum,<br />
the basic unit opens and the trimmer switches off. If necessary remove trimmer and place in<br />
carrying case.<br />
If you must repeat the trimming procedure, this can be done immediately by sliding the joystick<br />
to run position (restart trimmer – run). The program returns to the trimming procedure.<br />
5.5 Measuring kinematical pressure<br />
Press the OK button to measure the kinematical pressure.<br />

restart trimmer – run<br />
In the course of the kinematical pressure test the basic unit closes and the pressure continually<br />
increased. If the basic unit operates with a constant speed (upper bar graph) the system<br />
calculates the kinematical pressure. Test progress is indicated by the lower bar graph. After the<br />
basic unit has closed completely, the system produces a pressure that is higher than the<br />
adjustment pressure to verify the proper positioning and clamping of the pipe sections.<br />
Sight check:<br />
After workpieces have been moved into welding position, check whether the joint surfaces are<br />
plane, parallel and in true axial alignment. Should the joint surfaces show any misalignment,<br />
repeat the trimming procedure. For best results the workpiece ends should not be mismatched<br />
by more than 10% of the wall thickness and the maximum gap between the joint surfaces no<br />
more than 0.5 mm. This recommendation does not release you from your obligation to observe<br />
national welding guidelines.<br />
If you must repeat the trimming procedure, this can be done immediately by sliding the joystick<br />
to run position (restart trimmer – run). The program returns to the trimming procedure.<br />
