Absolutely. Some people have difficulty mastering the soldering process with larger gauge wires, especially when soldering 2 wires together.

Absolutely. Some people have difficulty mastering the soldering process with larger gauge wires, especially when soldering 2 wires together. The key is to understand the the soldering iron is used to heat up the surface to be soldered, not the solder itself. Yet, you can help create heat conduction using a small bit of solder on your tip applied to the wire surface. You can also apply solder to the components separately (like to the wire and the switch) and then put them together and use the iron to heat the solder together. Read Less

Answer: 
NO. For wire that large you'll need a soldering gun in the 100-140 watt power range, at LEAST!

Answer: 
No. With wire that thick, I would definitely go with a soldering iron that is more than 40W.it can be difficult to get the entire wire hot enough to solder if you're using a smaller iron, and that can lead to cold joints, the wire breaking at the joint etc.

Answer: 
This 40-watt iron is totally sufficient to solder 18-gauge wire. Even a 25-watt iron is enough. You don't need a 100-watt iron unless you are doing heavy duty projects like plumbing.

Answer: 
Mike, The 40 Watt iron should do the trick here. We recommend the lower watt irons, 15 and 25 watt, on delicate circuit boards and other electronics, and our 80 and 100 watt irons for heavy duty soldering. Your job falls right in the middle, so this 40 Watt iron will work nicely for you with enough power to get the job done.

Rated 3.9 out of 5 by 61 reviewers.
Rated 5.0 out of 5.0 by Great soldering kit! This is a really nice soldering kit that has all the bells and whistles that you could want. I'm really impressed with this set up and it works exceptionally well. Heats up quickly and is pretty precise! Comes with some solder, the soldering iron, stand and different heads. This is my first soldering iron but have worked with them before. Does a great job and I'm definitely a happy camper with the results. Highly recommend! September 11, 2016
Rated 5.0 out of 5.0 by 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. August 4, 2016
Rated 5.0 out of 5.0 by Ideal Weller Soldering Iron..... This Weller Soldering iron is ideal for creating stained glass lamp shades. Heats quickly. Melts solder evenly. I have been using the Weller Solder iron products for almost 50 years [ ! ]. Reliable. Long life. September 20, 2016
Rated 4.0 out of 5.0 by Iron it out I've been nursing an older model from the former electronics 'Shack' and goodness does this do so much better. Heats up fairly quickly and the LED lights are a great addition. Nice to have interchangeable tips too. One thing I wish they could have sorted out was the power cord, specifically the weight or pliability. The iron has a triangle shaped throat so it should sit nicely on the bench but the cord causes it to shift awkwardly even with the included "stand". Probably best to grab a different stand or a hands free option. Overall great upgrade for me. August 1, 2016
Rated 5.0 out of 5.0 by Works great This iron has been reliable and easy to use. I previously purchased cheap $4-5 soldering irons, but I had to constantly buy a new ones because their tips would corrode almost immediately and replacements are not available. The tip on this Weller is still in perfect condition after 3 projects. And this model comes with 3 different tip styles. The higher cost of this iron is actually a much better value over time. The LED lights at the tip, however, add only minimal light - not enough to light up your work area by itself. October 11, 2016
Rated 3.0 out of 5.0 by Best Unsupported Product Ever I bought this soldering iron from my local Home Depot about 6 months ago and since then I have been doing a fair share of soldering with it. The iron itself is pretty good, it does have a hard time holding temps which is minus 1 star. The 2nd star is lost because the soldering tip (as expected) run the course of it's life and needed to be replaced but the store does not carry them. September 30, 2016
Rated 1.0 out of 5.0 by Fair Is very cheap and i use 1 time and broken, is not a good product sorry September 13, 2016
Rated 3.0 out of 5.0 by Soldering iron stand The stand is to weak to hold in place should be thicker September 14, 2016
