Barry, thank you for taking the time to provide this advice.
Yes. I am very disciplined in cleaning the tip. I have a can of tin and use it on the tip.
What I did wrong based on the diagram was to touch the solder to the tip-side of the work rather than touch the other side. What I observed was the pad had not sufficiently heated and the solder did not flow from the tip to the pad.
When I reflow the solder I will experiment with 1) a narrow chisel tip which may provide a larger surface area to transfer more heat to the pad; and 2) increasing the nominal heat displayed on the soldering station from 750 to 850. The nominal heat on the display may not be accurate.
Thanks again for your advice. I hope to report back later in the week.
