Weller SP80NUS 80-Watts LED Soldering Iron

This is a fantastic iron FOR THE MONEY, a steal for under $20. Most soldering stations with replaceable tips have rather small tips, while they have precise temperature control and a fast heat-up time, they are too small for large connectors. See an image comparing it to a T12 iron tip. This iron fills that gap if you need to solder heat sinks, connectors, larger wires or copper plates. It heats up in about 2-3 minutes and remains hot (as you can solder with that) for over a minute after unplugging. I measured the power to be 74 Watts. There's no temperature control and the iron overheats for tin-based solders. The high temperature will also deteriorate the copper tip. If you want to use it for more than a couple of times, you will want to add some type of power controller, as dimmer, or simply a diode in series. I recently had a wall dimmer breaking (plastic in the switch cracked) and I repurposed the dimmer circuit for controlling the power to this iron. I put everything in a small plastic box, added a plug and this contraption works great. A diode in series with a switch to short-circuit the diode will work reasonably well too. The AC wire insulation is not silicone and will melt if touched by the iron. The good thing is that the wire is relatively thin, but it could have been more flexible. Overall it's a comfortable iron, the handle does not get hot, the LEDs are not that useful in a reasonably well illuminated are, but don't hurt. Great value!

85 Watts versus 65 really did the job in removing high power transistors known as MOSFETs from a failed circuit boards with lots of solder. 15 MOSFETS with 3 lead each, that's 45 leads for a project of this size. Sadly, my repair failed when it shorted and several transistors exploded. Partially mine and the manufactured board maker failure, fault. This soldering iron had no heat control. It was fixed with LED lights, which really did not help. The heat tip was flat and too big ,but I filed it down for the job. 85 Watts does the job. However, I strongly advise to use Flux when soldering electronics. Rosin core for that kind of gig. Cheers..Eugene

I've always gotten fine quality products from Weller, and this one was no different. It works just as you'd expect, great.

I purchased this solder iron for re soldering the ground connections on guitar tube amps. It takes a lot of heat to do that. This iron does a great job. The photos and description of this iron does seem to be confusing though. It doesn't say what type of tip comes with it, but shows two different tips (a pointed tip and a large chiseled tip). When I purchased it, it came with the large chiseled tip. That combined with the 900 degree heat works great for heating large surfaces. The chiseled tip would not work well for soldering small wires. You would be better off with the soldering station for that since the temperature is easier to control. But for heavy duty soldering and the low price, this is a good buy.

Against advise (too big) I got this for some pretty small solder points building a couple drones...glad I did. The added heat over a 40 watt lets you get in, apply solder, and get out. Even using the higher heat of silver-solder was no problem. Leads on BECs, plug connectors, ESC wires. The chisel tip is large and limits some work, you will still need a pointed 40 watt to work close to circuit components...but loving this 80 watter for 95% of the soldering I need to do. Bonus tip: Pair with the "Choice Rheostat Soldering Iron Temperature Controller" (I got mine here on Amazon from completeauctionservice). The 80 watt Iron heats quickly, and can get too hot for small projects and lead-tin solder. The Rheostat gives me a full range of control from hot but touchable, to full on 900 degree. They work great together.

I bought this soldering iron for a jewelry class I was taking. On the description it said some of it's uses was for jewelry making, and stained glass. My class involved making jewelry with a stained glass method. This iron was so terrible that it had to be tinned 5 times in 1 hour. It wouldn't hold the solder. It got way to hot! So hot that it kept turning the tip and base black. Some of the other students noticed that my iron was smoking while their Weller's (which was a different model) were not. The rest of the class was almost finished with their project while I had to end up borrowing the teacher's 100W Weller. I was MISERABLE and FRUSTRATED! The teacher told me to return the iron. She said she had never seen an iron that had to be tinned so much. This iron had a 2 prong plug...my teacher said the soldering irons with 3 prongs control the heat better. She wasn't familiar with this type of iron, being that it had a ceramic heating element. This hasn't turned me off from the Weller brand, but it has turned me against this model. 5 of the 6 people in this class had a 100W Weller which they had no problems with at all.

Tis was a great tool for the job. The handle was comfortable, the weight was as expected, not light but not overly cumbersome. The price was reasonable and the power rating was good. The heat is not adjustable on this unit. That would have been a bit better for my project. I made a small brass "stamp" that attached to the end so it could be used to mark items such as wood and leather.

First one went belly up after 2 uses, but they replaced it super quick -no hassle. Second one works really great (used a lot). No way to control the temperature on the unit itself, so you’ll need to plug it into a regulator of some sort. The heat will spike and ebb, but it’s easy to get used to the flow of how it heats. I haven’t had any issues. It gets hot enough the easily melt lead came if you’re not incredibly careful but works wonderfully for copper foil work. I’ll eventually upgrade but for a novice stained glass artist it does the job.

Está buena la construcción del cautin. No me sirvió porque calienta demasiado y quema la soldadura 60 estaño 40 plomo. :( probaré un cautin que regule temperatura.

Ça chauffe et Ça va bien pour souder plastique de Vtt , attention très chaud

This is a heavy duty version of the spg-80 I think as it takes the same tips. It seems to last longer and I dig the light. That is saying a lot as I am hard on these things! Gets good and hot….o do wish I could buy the replacement tips when ordering

Excelente producto calidad y precio

Il trouve rapidement sa chaleur, les faisceaux lumineux sont pratiques pour indiquer qu'il est branché et pour réaliser la tâche, il se tient bien (bien balancé), l'embout semble solide pour une bonne période, mais il chauffe trop pour réaliser du vitrail efficacement.
