The Weller SP25NUK is a high performance, standard-duty consumer Soldering Iron with the latest LED technology. 3 LEDs deliver light to the application for superior accuracy. A triangular from housing captures the LED's. Once the tip is in position, the hand naturally gravitates to the triangular area to provide a more stable and effective way to control the tip position. The soldering iron delivers both comfort and flexibility. A round, soft-grip, non-slip handle design helps relax the hand during extended use. It easily provides a mechanism to roll and position the tip for application needs. To ensure long life, the soldering iron comes with a stainless steel heater, impact resistant housing and heat resistant LEDs. Ideal for printed circuit boards, radio controls and indoor lighting.

Lead free Rohs compliant solder has a higher melting temperature than good old 60/40 lead solder. As long as the tip temperature is maintained high enough for the joint being soldered the wattage is less important. At work for SMD reworking we use 15 watt irons, for some of the 8 layer pcb's with large areas of groundplane I use an 80 watt iron. All of our irons are user temperature controlled so when using lead solder for our aeronautical and military clients we run at about 330 deg C but for non lead solder about 390 deg C. Spare tip availability for Weller irons should be good unlike some other irons that are available, for cleaning the tip a pan scourer type should be used and not a damp sponge as this will reduce tip life .

40w version is £12.55.
25W is too low for anything. Waste of money. Get 40W
Definitely need 40w with all this lead free solder everyone uses these days

Surely the power rating has more to do with the size of the job you're trying to solder?

Certainly, for mains cable, and big terminals, 25w will struggle to knock the proverbial skin off a rice pudding but I can think of a lot of things (surface mounted devices for example) a 25w will not only melt the solder, it'll also lift the track right off the board, and even then, probably fry the component as well!

The only Weller component I have used which performed this task more efficiently was a "soldering gun" (I mean, of course, to ruin boards and components) - horses for courses, a precision microelectronics tool this isn't, industrial grade large-scale jointing this sin't either!)

Great answer, I only dabble in the stuff
Excuse my ignorance and thanks for such an interesting comment
25W is fine for most electronic work, I've been using an old 25W Antec for >40 years

Yes I've got one of the posh digital temperature stations, but much of the result is down to practice and the appropriate tip.
also, ditto what trannyboy said

So is this variable temperature?
lead free is terrible Solder... stick with old stuff.
As for 25w being to "small", I used a 15w iron for years for soldering components onto pcb.
I've had a chance today to check out the tip availability, plenty of places you can go with different prices for the same tips. The way they fit in the iron is by a screw thread that screws into the heating element, as long as they don't seize or become too loose they will be fine for most home jobs and that wood burning patterns craft ,pyrography I think it's called.

Nearly got this as I have a large soldering / hot air station that is a bit of a pig to use in cars. I spotted the Dremel Versatip set for £23.75 and took a punt on that homebase.co.uk/dre…599

It's not really a sensible choice to use leaded solder for DIY projects where extraction will be non existent.
