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

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.

Ordered a high wattage version of the same low priced soldering irons I have been using for years because I was soldiering to thick copper heatsinks and needed some serious heat to make a solder joint quickly enough to not melt the components. It does work. It does exactly what it is supposed to do, get hot, stay hot. I did take one star off because it is just so unwieldy. The tips are the size of the fat pencils they give you in kindergarten. After this I ordered a soldering station capable of supplying this kind of heat when I need it through a tip small enough I can put it where I want it. If you're going to buy this and then buy a smaller iron for smaller jobs you're already half way to the price of a good soldering station, save money and frustration over the long haul and invest in one.

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.

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.

Ok, this heavy duty solder iron is fairly big, the tip-rod is the diameter of your pinky. It heats up fairly fast or in about 3 minutes. That's good for this size tip. You need to clean the tip with wire brush now and then, heat oxidizes solder and turn dark. So brush it, clean with flux, brush again and tin a little. That'll last you a while again. I use is to weld 22 gauge sheet metal boxes. With sheet metal surface sanded and fluxed, it'll go through the tinning and soldering fast. You can do a 1 foot square box in about 1 minute with a clean tip. Good enough for car battery cables (4gauge), copper sheet soldering and 22 gauge or thinner steel sheet metal. The Tip-Rod support piece is of thick 16 gauge steel, very strong and good quality. The body is heat resistive plastic with the LEDs.

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

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.

La calidad de weller en cantines tipo lápiz son muy buenas 100% recomendables
