Where each value comes from

This source states these in separate places, so each value is shown with the passage it comes from.

ESAB-recommended SAW (submerged arc) filler

The source prints this value inside the passage below but does not name it there. The passage shows where it appears; what ties it to this record is the position on the page, not anything the passage says.
