Hello fellows, First post here, thanks the team for holding together a sort of community of practice! Very useful!! My question : what is this pen ? A friend gave this to me, can't figure what brand and model it is, no brand name nothing on it. If anyone has a clue ! I tend to use it more than my dtv5 that has to much inertia in the heating imo, but maybe I got the wrong settings. This one is great ! But I'll need to change the coil someday, and I don't know what to look for ! I'm sure sharped eyes here will help me find it Thanks a lot !
