Where'd you get the Hakko 936 ? Those have been discontinued for a while now (I have 2 of 'em)

Ya, 28AWG is small stuff. I think it's still within the ampacity limits for the current he's running, but might be worthwhile upsizing that several iterations to pad the safety factor. Thinner wire also presents more resistance & therefore voltage drop. This could be a factor depending on how many are hooked up in series with that tiny wire. Look up ampacity & you'll find plenty of charts. Here's one example:

According to the chart, max current for 28AWG in a chassis wiring application is 1.4 amps or 1400 milliamps. That stuff could be tricky to solder as well. A little too much heat & the insulation will shrink back a ways or even start cooking.
