## Questions & Answers

**Q: Any updates or recent experience on the often mentioned quickly corroded tip?  It is still not durable?**
A: Mine corroded and faded away pretty quick. Got some replacemet tips and became religious about tinning the tip at the start of a session and end.  Be sure to unplug if your going to leave it for anytime at all.  These dont really have any kind of heat regulation that i can tell. they will dump all their power all the time. So when you leave your iron in the stand it will get into the 900 degree range pretty quick.  and that will eat your tip in no time.  If you plan on doing any long sessions id say get a cheap soldering station.  much easier to use and only a little more expensive if you pick up a hakko clone

**Q: is this the weller soldering iron that has a thread in tip?**
A: We check and there's NO thread in tip note 
Tech Support .

**Q: Is the tip already tinned?**
A: Yes. For a few minutes until it overheats and heavily oxidizes and becomes untinnable.

**Q: replaceable tip?**
A: Yes, the tips drop in, held in place with a screw.
