The second welding machine running on its first evening
The second welding machine runs on its first evening shift, with carts of parts waiting beside it. The camera shows no welding on the Sep 7 evening shift, so this is the first evening shift with welding.

The count of parts waiting at welding, before and after
The ERP counts the sets of parts waiting to be welded and how many days of work that adds up to. The queue held at about 9,000 until the second machine ran in the evening, then fell by about 3,000.
