I bought this iron to solder 22 connections to a circuit board not much larger than a postage stamp. My eighty year old hands and eyes approached this task with a lot of trepidation, but the iron performed flawlessly. Just the right amount of heat to do the job. I would prefer a chisel tip to the round one but it did the job. It would not work well for larger work. For regular wiring get at least 40 watts or larger.
