Cheap soldering irons are pretty horrible to work with, compared with a good temperature controlled iron.

If you are seriously interested in electronics, save up and buy a GOOD soldering iron with temperature control, a reasonable power rating (say 50 or 60 watts) and interchangeable iron-coated bits. A price tag in the $50 to $100 range might seem expensive, but it will last you for 50 years, not one or two. The trouble with cheap low power irons is they overheat if they are left switched on and not used, but they don't have enough heat capacity to deal with the times when you need to solder something big, so you lose out both ways in terms of ease of use. And iron coated bits don't need endless cleaning, filing into shape, and tinning. Just dab the hot bit on a damp sponge, and the "steam clean" makes it like new again.
Every word of above is true.

for a one time repair on a $10 multimeter, , borrow a good iron or buy a cheapie.

If you get interested in electronics work, which is a LOT of fun,
you'll soon crave a really good iron.

So here's the update:
I went to an electronics store with my multimeter and spare fuses, the guy working there was kind enough to solder it for free so I bought some 555 IC and capacitors from him. The multimeter works like a charm! :D

But I'm considering getting a soldering iron myself, I was curious how much it would cost, so I went in a hobby store and they had soldering irons for about 5 euros. Might get one soon.

5 sounds a bit cheap. You need one with a stand and sponge pad. Not less than 40W power, I reckon. Look on eBay to get an idea of prices.

5 Euros is a "bargain basement" price, and probably quality as well.

This is what I would call a "good" soldering iron - similar to the one I've been using for the last 30 years. Even iron coated bits don't last for ever, but it took me about 20 years to wear out the first one. (The others in the original set that came with the iron are still OK.)

Antex is another "good" brand name.

i worked in an electronics factory where we used the Ungar or Weller handles that accept screw-in heating elements of various power ratings. I still use one at home.

The temperature controlled ones are much nicer to use.
Looks like one might do pretty well on Ebay... try searching on 'ungar soldering iron' , or whatever brand is common where you live..

You could put a lamp dimmer and receptacle in a double outlet box for a "poor man's adjustable " iron. But you'd have another ten dollars in the rig.
