Thermaltronics TMT-TC-2 Tip Tinner (20g) in 0.8oz Container

Your soldering looks good. Get a little brass scrubber to clean your tip. If you wipe it off a few times and solder still doesn't want to stick to the tip, use tip tinner. It refurbishes the soldering iron's tip to hold solder again. It's cheap and magical. https://a.co/d/09R64iXq https://a.co/d/0dMvueD3
