The last can is not welded at the end, sometimes the canbody remains in the crown.

Corretive:

• Delay off time drives has to be increased (access over spanner symbol, key symbol, customer password, key symbol, time settings, drives off delay).
• Check the overlap in the end, maybe overlap is too small, and it looks like not welded.
• Also possible: time “jam in weld section” (longest canbody?) did stop the welder, error message should appear in the touch screen!
