The weld seam is faulty or not properly sealed in one or more places.
The rubber on the counterpressure bar is not evenly installed.
Flatten the rubber.
The edge of the bag is dirty (inside and out).
For a perfect weld seam, the edge of the bag must be dry and grease-free in the area of the seam.
Fold the edges of the vacuum sealing bag outward for filling.
This will give you a clean weld seam.

Position the edge of the bag smoothly and without creases along the sealing bar.
The sealing bar has overheated.
