The test mode enables the optimal welding speed to be determined. To do this, select the “Test” tab in the upper area of the
screen. The test mode will guide you through the test step by step.

For the test, the
welding nozzle (12)
and
transport rollers (9)

Prepare a test strip of slightly more than 550 mm/21.7 inches and position the material be-
tween the clamps.
Enter the approximate welding speed in the left-hand window area. The welding process for
the test strip begins with +50% of this approximate welding speed and is linearly reduced to
-50%. Start the test weld using the foot pedal of the “Start Weld”
pedal unit (7)
.

Carefully tear the test strip starting from the beginning of the weld and measure the distance
from the start of the test strip to the point where there is a good weld seam. Enter this value in
millimeters or inches in the input window displayed.
Note:
If the strip was welded well right at the start of the seam, then carry out the test mode
again with a higher approximate speed. If the seam is insufficiently joined, perform the test
mode again with a lower approximate speed.

The optimal welding speed is calculated on the basis of the approximate welding speed and the
distance measured. Confirm with “OK” to adopt the value and switch to the Home view.
