OhNo! My soldering iron came yesterday and it works well and is fairly good, but after i tested if it could melt the solder ive got after i turned it off i expected a quick cooldown time but it took longer than i expected and i accidently melted some plastic on the side on the tip, fairly high up. I dont know what to do!? Also should i wipe before i stop using, some people say you should wipe and then melt some solder to flux it and stop for oxidising!?!
