A long delay before cutting and releasing after strapping with the Extend EXS-206 can be caused by the following:

1. LS3 (limit switch) is inoperative or improperly adjusted.
2. Clearance between the welding clamp and end gripper is too great.
3. The cutting surface on the welding clamp is dull.

These issues affect the timing and operation of the sealing and cutting process.
