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.

Rated 3.9 out of 5 by 51 reviewers.
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 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 Medium Duty MUST HAVE The Weller brand has always been the 'go to' brand for soldering equipment. This "medium duty" 40-watt tool is no exception. I have now used it to repair a computer board that needed hard part replacements and on a wood power Router that needed to have the power cord replaced. Neither of these repairs / replacements gave this new LED Weller a moment of problem. These is definitively a go to tool for light to medium duty repairs. August 5, 2016
Rated 3.0 out of 5.0 by Good enough This iron is compact, light and heats up quickly. No problem doing the job, The LED lights, while not extremely bright, do add a bit of helpful light where it's needed. Whether you end up liking an iron or not basically comes down to the ergonomics, and this one is a little odd. There's a rubbery grip over a widening area where your fingers are obviously supposed to rest. In front of this is the housing for the LEDs, which causes the grip to be a little further back than I'd like. To get better control of the tip I found my fingers wanted to creep forward and grip the LED housing, which isn't rubber coated, so I don't get any value out of the actual grip. Other users might not have this issue. It's basically a good and useful small iron and the lights are nice. There's a very minimal "stand" included, just a little piece of sheet metal that barely keeps the iron off the bench. I don't think this is adequate and is likely to cause trouble. Better to either include a real stand (obviously at a higher price) or make it clear that one needs to be purchased separately. August 7, 2016
Rated 5.0 out of 5.0 by 40W Weller Soldering Iron I'm not a pro but this soldering iron works great and does its job the way I need it to. I'm sure their are better soldering iron in that market but for the money I sent I'm very happy. August 2, 2016
Rated 5.0 out of 5.0 by Good utility, medium-duty tool This iron heated up quickly, was good in the hand, and came with easy-to-change tip shafts, with a good variety if profiles. Also came with a rest.. Worth the cost. July 26, 2016
Rated 5.0 out of 5.0 by love this tool this tool is perfect for my electronics installs, the multiple tips make it perfect for small jobs July 25, 2016
Rated 5.0 out of 5.0 by Great soldering iron This soldering iron does the job. Would buy again. July 12, 2016
