## Questions & Answers

**Q: what temperature does the 40W get up to in degrees F?**
A: It also depends on the voltage of your home.  So if it varies between 115v to 125v then it will be less or more heat.

**Q: I'm new to soldering. I have practiced with the soldering included in the kit, but would like to try repairing sterling silver jewelry. My question: What type of sterling silver soldering should I consider buying?**
A: This is for electronics work only. DO NOT attempt to use this for soldering jewelry. A special torch is needed for that.

**Q: for electronic work builiding diy amplifier which 25 or 40watt version?**
A: 25W is the perfect size for a fixed wattage soldering iron when working on electronics. The solder will flow very well, and you reduce the change of overheating the components or the board significantly. With a 40W iron, it is extremely easy to damage both the board and the components. The only time that I would ever recommend a 40W iron, is if you are having trouble soldering large/heavy wiring.

P.S. NEVER solder any wires that connect directly to the power line. Solder can, and will explode in a flash, if there is a short.

**Q: Are any of the included tips ironclad?**
A: All 3 are iron clad copper.
