I’ve wasted hours at RCC, not getting the soldering irons to work. I’ve burned myself, but could not successfully create good connections. 4 hours, 2 joints.
I was so frustrated. I was at the RCC from 4:30am to 8:30am. I decided to buy my own soldering iron from the Source. I did a bit of research and the variable soldering iron seemed good and was within my budget.
The best instructables for soldering suggested 60/40 solder and it really does work so much better. I can solder connections at an insanely fast speed now, so I do know how to solder properly. It was just the soldering irons at RCC.
