Most of the youtube videos regarding wiping a joint use 60/40 tin/lead

60/40 tin/lead *is* eutectic, but that is not a typical plumbing solder,
which is closer to 60/40 lead/tin.

I always thought for wiping
you used a 70/30 lead/tin where you had a wide temperature range when
the solder is workable as it cools.

Yup, 60/40 lead/tin (or with small amount (=3%) f antinomy) will cross
the solidus line at about 183 deg C, and the liquidus at 234.
