I need to solder some 18 gauge wire together will this be sufficient enough to do that or should i step up to the 100.

Asked by: mike
Mike, I had great success with soldering three 16ga stranded wires in a single point. I found the solder flows evenly and the heat output is great.

The light is a nice touch to light up the specific work area around the tip. It has a good size grip. This is a great tool for electronic soldering work - appropriate heat for soldering and de-soldering components.

Hands down the best soldering iron I've owned, I'm 51 and that I've owned my fair share is an under statement, this isn't being used for professional purposes it's for personal use...but I used guns from Weller growing up, and have had cheap/inexpensive ones and this is very comfortable in the hand easy to use and you can get other tips for it for more uses is GREAT...Weller knows what a good product is and this is one of theirs, discover for yourself they have a whole line of soldering tools for you to choose one of your own...Enjoy

Rated 5 out of 5 by from Useful Soldering Kit General: Good quality and useful soldering iron. The LED lighting comes in very handy when working outside of a work bench. I’ve used it to solder wires on a boat where there is low light; which is when you can really appreciate having the LED lights on it. Material/Construction: Looks and feels like a good quality soldering iron. Functionality: Works as it is supposed to. Heats up fast. There is not temperature control, so you would have to be a little more careful when soldering. The smaller tips that come with the kit are useful when soldering smaller components on circuit boards. The iron is fairly light which is nice when working with it for an extended period of time.

Gets hot within a couple minutes and melts and spreads solder really well. The 3 tiny LED lights at the end of the handle are really handy to see what you're soldering better in dimly lit locations. The metal stand is kinda cheesy and no carrying case, but overall it gets the job done. Comes with multiple tips which is nice too. No regrets on my purchase!

The very nice soldering iron I use for my stained glass work died and I didn't want to hold my work while I had one shipped in from my glass supplier, so I picked this up. It worked, but not well for the work I needed. I will be replacing it with a more powerful iron meant to be used for stained glass and keeping this as an emergency backup.

Soldering tips are quite durable, and the LEDs are a nice feature when working with microelectronics. Temperature range is great for lead-free solder without worry of burning components.

Needed to solder XLR ends to microphone cable. Needed to wire brush the tip to keep it clean of course. It was 32 solder points in all. Knocked out the job very quickly.
