Thermal Bonding the Liner (continued)
6. Slowly run the nozzle parallel to the upper edge, using the roller to evenly
thermal bond the liner pieces back together.
• The edge of the upper liner should show some signs of “bleed”.
• Discoloration and smoke is a sign that the bond is too hot, check
temperature, adjust speed of bonding and clean nozzle if necessary.
7. After bond has cooled (approx. 10 min) check the integrity of the weld using the
Seam Test Tool. If any gaps exist, re-bond where needed.
