## Questions & Answers

**Q: Are these made in the USA?**
A: Thank you for your question. Wirefy solder seal wire connectors were designed in New Jersey; and manufactured in a state-of-the-art production facility located in China.

**Q: Which heat gun or torche is best to use with these?**
A: Heat gun is better than torch. Personally I use a cheap 300 W heat pen. You want to heat it slowish, turning the part and moving, to give the solder time to melt without burning off the plastic. A lil heat gun worked great for me.

**Q: Can these be used on low voltage wiring; outdoor led lights for example?**
A: Yes, these Wirefy heat shrink solder & seal connectors can be used on low voltage wiring. These connectors are waterproof, and can be used in outdoor wiring projects.

### ⭐⭐⭐⭐⭐ Best way to join wires and waterproof
*by P***K on 11 August 2018*

Excellent way to join wires I used it to rejoin a wireing loom on a car very quick,neat and tidy and good connections every time no waste

### ⭐⭐⭐⭐⭐ Much easier than soldering.
*by A***N on 19 August 2018*

Works well. First time I tried it I didn't use enough heat, second time I used a more powerfull lighter and it was perfect.

### ⭐⭐⭐⭐ easier than soldering
*by A***R on 17 March 2019*

these obviously cant replace a soldering iron but for joining wires they are quick and easy, i did find that to get the solder to melt i had to use a lot of heat from the heat gun which at least on one occasion did melt the plastic slightly too much and possibly exposed some of the wire (was very small and couldn't tell if the plastic had been breached or not) but i used some normal heat shrink wraps over the top anyway. Overall i would recommend them
