 Press text field, the work pieces move together and the drag flow pressure is measured.
The measured drag pressure will automatically be added to the equalization, warm-up and cut-
ting pressure.
Stay a safe distance away from the machine. Do not stand or reach into the machine.
Keep other people away from the work area!
 Check, whether the pipes are resting firmly in the clamping elements, whether the welding
areas are plane, parallel and axially aligned.
Should the joint surfaces show any misalignment, repeat the trimming procedure. For best re-
sults the workpiece ends should not be mismatched by more than 10% of the wall thickness and
the maximum gap between the joint surfaces no more than:
Ø ≤ 355mm = 0,5mm, Ø 400...< 630mm = 1,0mm, Ø 630...< 800mm = 1,3mm.
This recommendation does not release you from your obligation to observe national welding
guidelines. Clear away any remaining shavings with a clean brush.
CAUTION! Do not touch the trimmed, ready to weld surfaces. Ensure that the surfaces
are free of any and all containments and foreign objects!
Welding process in premium mode:
Risk of injury! Keep a safe distance from the machine when mechanically closing
clamps and moving workpieces. Keep hands, limbs and objects such as clothing, tools
etc. away from running machine!
 Insert the heating element between the two work pieces in the basic machine, and make
sure that the heating plate supports are seated in the notches of the removal device.
 Close the machine. The equalization pressure is automatically set. Hold the pressure.
Now all welding parameters have been stored, and the log activated.

The form shows the temperature of the heating plate.
The display bar shows up in blue if the temperature is too low, and in
red when it is too high. When it is in the target range, it displays as
green.
